The EMS Synthi AKS is a portable analog synthesizer made in the early 1970s by Electronic Music Studios (UK). It's famous for its matrix patchboard instead of patch cables, allowing users to connect oscillators, filters, envelopes, and other modules in a unique, compact format. It has a distinctively experimental, unpredictable sound, ideal for sound design, ambient textures, and electronic effects.

Usage:

Commonly used for spacey effects, glitches, drones, and modular-style sound exploration.

Known for creating robotic, alien, and cinematic textures.

Notable artists, songs, and albums:

Pink Floyd – “On the Run” from The Dark Side of the Moon (1973): the Synthi AKS was used to build the entire sequenced synth line.

Brian Eno – featured throughout Another Green World (1975) and Ambient 1: Music for Airports (1978): used for ambient textures and sonic experimentation.

Jean-Michel Jarre – used in Oxygène (1976) and Équinoxe (1978): for spacey effects and sweeping synth patterns.

Aphex Twin – rumored use on Selected Ambient Works Volume II (1994): for eerie, modulated soundscapes (though not officially confirmed).

Daft Punk – used during the production of Random Access Memories (2013): particularly for layering effects and unusual timbres on tracks like Touch.

The Synthi AKS is a cult classic—unpredictable but powerful for those who embrace its quirks.

Pictured is my current modular rig* (1,2,3). In addition to these cases I currently also use a Make Noise Strega and 0-Ctrl, Moog DFAM and Spectravox, and Pittsburgh Modular Voltage Lab 2. All recordings played live, processed through Elektron Analog Heat mk1, and recorded via Zoom H4n.

Each system is housed in an Intellijel performance case. Each is intended to fill a specific purpose, and to be playable as its own instrument - though of course they're more powerful than the sum of their parts when put together.

The first is a "modular drum machine" with many voices and complex, focused sequencing. There's a couple of fun routing options and effects, but it's intended to be like a groovebox.

The second is, for lack of a better word, a texture processor. Feedback, sample mangling, and smooth tactile control are the name of the game here.

The third started off as a more classic synth, and can still fill that role with several oscillators, a filter, and a delay. But the open ended nature of so many of the modules allows for much feedback patching of CV and audio for various glitchy ends.

*The bottom row of each case is for planning purposes of changes to make, and not reflective of a secret third 3U row in the performance cases.

[taperwolf]

Oh, I just had a "right, it's all voltages" Eurorack moment — I should totally figure out the pot levels required for the CV channels in my sequencer to trigger the inputs on my "Toy Drum" module. By considering the gate out pulses as eighth notes, and running the two CV channels in parallel, I can actually coerce it into controlling a whole kick/snare/hats drum pattern.

I could then either take that same eighths pulse and clock divide it for a melody off the S&H, or work backwards and be clocking the sequencer from the BeatStep, which is sequencing the melody line.

(Obviously I still need to get a proper Turing Machine and more other general sequencing capabilities, but the prospect of a whole drum sequencer off the two-channel analog sequencer was exciting for a moment.)

DOVAL Unveils “Mixed & Covered 2”

Featuring synth-wave renditions of 10 timeless tracks

Musician Adrian Doval, known as DOVAL, returns with his second album of synth-driven reinterpretations. Mixed & Covered 2 takes ten well-known songs and gives them an electro-pop makeover. With a total running time just under forty minutes, the album strikes a balance between concise radio-ready cuts and an immersive listening experience with a retro flair.

The track list reads like a highlights reel of pop and rock history. DOVAL tackles Martin Solveig’s “Hello,” Maroon 5’s “Memories,” Justin Bieber’s “Love Yourself,” Neil Diamond’s “Sweet Caroline,” and One OK Rock’s “Wherever You Are,” among others. Each cover stays true to the core melody of the original while adding layers of warm synth ambients, crisp percussion, and analog-style leads. The album’s synth textures range from bright, bell-like leads to deep, rounded bass tones. Layers of softly modulated pads create an undulating backdrop, while precise arpeggiated sequences punctuate the rhythm. Subtle analog warmth and restrained reverb give the mix cohesion, and occasional tape-style artifacts add a slight vintage grain without overpowering the clarity of each element.

The album flows smoothly from start to finish. At ten tracks, it remains focused, and the total length under forty minutes helps maintain momentum. Tackling such iconic melodies is no small feat, yet DOVAL transforms each song into an electro-pop statement. He infuses his own style, warm synth textures and crisp percussion, while honoring the emotional core that made the originals resonate. The result feels both familiar and uniquely DOVAL’s vision, genuine and heartfelt.

With Mixed & Covered 2, DOVAL cements his place in the electro-pop scene. The album’s immersive sound design and throwback synth tones offer a beautifully nostalgic take on beloved hits, so dive in!

2nd synth composition/"tutorial"

For this project, I used two things, the Moog Subharmonicon, and pent up stress. Though both are equally important to this project, I can't and morally will not allow myself to give you a tutorial on stress, and so that leaves me with discussion of the Subharmonicon, or as I will call it, the S-H. The S-H is a funky little synth that prides itself upon being built around subharmonics and polyrhythm. Two concepts that, seemingly unrelated, are kind of the same thing at different speeds at different levels. When a polyrhythm is played fast enough, it registers as a pitch, and different divisions of polyrhythm correspond to different pitch, so the synth does both. What this effectively does is allow the user to change one of the four rhythm dials to divide differently, changing the rhythm to fit their needs. Unconditional, but in practice quite fun to mess with. Additionally, the synth allows the user to put together chords by dividing two sub oscillators from a main oscillator, of which there are two groupings, leading to at maximum, six oscillators. Though the main pitch and intonation can be chosen for the main oscillators, the four sub oscillators merely divide from the main oscillator, mimicking the polyrhythm feature in the sequencer. You see, it all lines up. Additionally, there are some basic functions for a filter, an attack/decay, resonance, cutoff, volume, as well as a patch bay to allow the user to modulate these systems, either in a larger synth setup or on its own. It's a niche synth, but its strengths really do shine in unconventional ways, and I find myself coming back to it more often than my others analog synths. The piece itself takes some advantage of this, staggering the "horns," and dividing their pitches irregularly. It sounds like an impending, slow, booming call of some malevolent entity beyond understanding, which is partially informed by my anxieties. Get therapy, kids, don't be like me. If you ARE like me, find outlets, music is great.

Lab 9: Servo Motor Shimmy

In the servo motor lab, the goal was to program a standard servo motor using an Arduino to perform a choreographed “dance.” I connected a 5V hobby servo to an Arduino Uno and wrote a sequence of movements that gave the motor a rhythmic, shimmying effect. It slightly reminded me of the beginning part of “Shimmy Shimmy Ya” by Ol’ Dirty Bastard—each little jolt of the servo felt like it was hitting the beat, bouncing left and right in this mechanical groove.

To start, I connected the servo motor to the Arduino using a simple wiring setup. The power and ground pins of the servo were connected to 5V and GND on the Arduino, and the signal wire was connected to analog pin A0. I also had a second set of power and ground lines running directly to the servo. After installing the Servo library in the Arduino IDE, I was ready to get the motor moving.

Here’s the code I used to make it “dance”:

#include <Servo.h> // include servo library

Servo servo; // create servo object

void setup() {

servo.attach(A0); // attaches the servo on pin A0 to the servo object

}

void loop() {

servo.write(2000);

delay(100);

servo.write(170);

delay(50);

servo.write(40);

delay(100);

servo.write(0);

delay(0);

servo.write(1000);

delay(150);

servo.write(1250);

}

This loop sends the servo to a series of angles with short delays between them, which creates a stuttering, shimmy-like motion. The timing was key—I had to play around with the delays and angle values until I got a rhythm that felt intentional and dance-like. The result was a fun, jittery little movement that definitely hit three or more distinct positions. I didn’t use a potentiometer or anything fancy—just clean wiring and code.

One of the biggest things I learned was how servo motors actually operate. I went into this thinking the motor might spin like a wheel continuously, but I was surprised to find out it moves to set positions and holds there. That made it more like choreography than just rotation. I also learned about how PWM (pulse width modulation) is used to control the servo’s position and how timing impacts its movement flow.

I didn’t run into any major technical issues during this lab. The most challenging part was just having patience as I adjusted the angles and timing until the dance looked right. It was also fun to see how changing just one delay or angle could completely alter the rhythm of the movement.

In the end, this lab made me see servos not just as mechanical parts, but as expressive components. It was simple but cool to program a little “performance,” and it helped me understand the basics of motion control in physical computing. The shimmy dance might not win any awards, but it definitely had style.

Thyroid "hot spots" incidentally detected by whole body Fluorodeoxyglucose-Positron Emission Tormography (FDG-PET) scan Fluorodeoxyglucose (FDG) whole body positron emission tormography (PET) scan is being used more often in the diagnostic follow-up or work-up of patients. In such conditions, positive PET scans with unanticipated hot spots within the thyroid region could be given the definition of thyroid FDG-PET incidentaloma, a name analogous to unexpected sonographic thyroid modules. A description of eight consecutive patients referred to the endoctrine department due to thyroid "hot spots" is given, incidentally detected by whole body FDG-PET scan. By applying ultrasound, histology reports, and fine needle aspiratory cytology (FNAC) in an experiment, an identification of pathology underlying thyroid FDG-PET incidentaloma will be attempted. FNAC showed a hint for surgery in all patients. Surgery has been carried out in 7 patients. There was a correct identification of malignancy in five patients; two having medullary thyroid carcinomas, one with lymph node invasion, and three having papillary thyroid carcinomas with attack through the thyroid capsule in two of the PTC cases. In two patients having a positive FDG-PET scan, FNAC showed indication of follicular neoplasms, and final reports of histology indicated follicular adenoma. In the last patient, FNAC disclosed a follicular lesion, but no surgery has been carried out so far. Summarily, a small series of successive thyroid FDG-PET incidentaloma cases is obtainable and suggests a high rate of clinically relevant malignancies (Wang, et al., 2000). Introduction The discovery of thyroid incidentalomas takes place through various ways. Normally, they are detected in the process of an imaging study, such as ultrasound (U.S.) or computerized tormography (CT) for suspected non-thyroid diseases. U.S. studies account for prevalence of a nodule ranging from 19 to 46% in the general population. The risk of carcinoma in insubstantial thyroid nodules range from 1.5 to 10% (Burguera & Hossein, 2000). Fluorodeoxyglucose (FDG) positron emission tormography (PET) is different from conventional imaging methods, such as CT and U.S., that depend on alterations of the morphology for tumor detection. It is actually a functional imaging method that depends on in vivo visualization of lesional glucose metabolism. Malignat and inflammatory lesions indicate elevated rates of glycolysis and glucose uptake (Fischman, 1993). In thyroidology, the clinical value of FDG-PET is set up in the follow-up, and localization of reappearances in a subgroup of thyroid cancers, that is, papillary and follicular thyroid cancer reappearances with increased thyroglobulin levels and negative radioiodine scan of the whole body (Wang et al., 2000), and metastatic medullary thyroid cancer. On the other hand, there is no reputable function of FDG-PET in the diagnosis of exceedingly prevalent cold thyroid nodules. To distinguish recurrent benign from uncommon malignant lesions, the preferred approach now is fine needle aspiration cytology (FNAC). FDG-PET is progressively used in the diagnostic work-up and in the follow-up of patients in departments of medicine and oncology. In the process of a whole body FDG-PET for a non-thyroid malignancy or a para-neoplastic event, a scan with an unpredicted hot spot inside the thyroid area is seldom found. I would like to describe this phenomenon as a thyroid FDG-PET incidentaloma. This communication depicts the first sequence of eight successive thyroid FDG-PET incidentaloma cases. Subjects and Methods Subject A A 51-yaer-old male was referred to a gastro-enterologist due to an elevated carcinoembryonic antigen (CEA) value of 12.4µg/liter, the normal value should be less than 3µg/liter. The results for Clinical examination, CT scan of the abdomen, gastroscopy, and ileocoloscopy showed negative. A FDG-PET scan exposed a hot spot at the right side in the thyroid area. A consequent calcitonin value was eminent at 158ng/liter while the normal value should be less than10ng/liter. Thyroid U.S. indicated a hypoechoic nodule in the right lobe. FNAC guided by Ultrasound suggested a medullary thyroid carcinoma (MTC). An assessment to rule out pheochromocytoma (urinary catecholamine excretion and adrenal U.S.) resulted negative. Overall thyroidectomy and bilateral careful lymph node dissectionexposed a gray 1-cm diameter lesion in the right upper pole. This tumor comprised of sheets of large polygonal cells having eosinophilic cytoplasm divided by fibrous stroma. Positive immune-staining for CEA and calcitonin proved the diagnosis of MTC, lymph nodes did not have metastasis. At post-surgery assessment which was done 3 months later, serum CEA and calcitonin were normal. Subject B A 71-yr-old female got back to her gastro-enterologist for postsurgical assessment 3 months after a supposed curative resection of a pT2N0M0 colonic carcinoma. The hemoglobin value had normalized. The CEA value, however, continued raised at 56.8 µg/liter in comparison to the preoperative value of 42.7µg/liter. A CT scan carried out on the abdomen discovered neither local reappearance nor liver metastasis. A FDG-PET scan indicated a cervical hot spot related to the right lower thyroid lobe. A high calcitonin 853ng/liter compared to the normal which is less than 10ng/liter, the U.S. image of a hypoechoic nodule (20 mm) in the right thyroid lobe and the outcome of FNAC (immunocytochemistry for CEA and calcitonin was positive) held up the suspicion of MTC. A preoperative assessment for pheochromocytoma was negative: adrenals were usual on the earlier performed CT scan, and the secretion of urinary catecholamines was usual An entire thyroidectomy and bilateral careful lymph node dissection exposed a gray tumor having a diameter of 22mm in the right lobe. It comprised of large polygonal cells divided by fibrovascular septa. Congo Red stain indicated amyloid deposits in these septa. Tumor cells marked positive for chromogranin and calcitonin verifying the diagnosis of MTC. A single ne lymph node in the region of the right periodic nerve had an MTC metastasis. Further radiotherapy (50 Gy) of the neck was consequently carried out. Afterward, CEA had gone back to normal (1µg/liter) and calcitonin stayed a little high at13ng/liter. Subject C A 53-yr-old female was brought before the rheumatology department for examination of anemia. A mixed connective tissue disease was earlier alleged A normochromic anemia having a hemoglobin value of 80 g/liter could not be explained. Bone marrow aspiration and biopsy indicated weak erythropoiesis and a preponderance of myeloid precursors. These non-pathognomonic modifications suggested the possibility of a thymoma or a paraneoplastic occurence. A CT scan of the thorax exhibited a clearly demarcated mass in the left anterior mediastinum relating to a thymoma or lymph nodes. An FDG-PET scan indicated two hot spots, one relating to the left anterior mediastinal mass and a second one relating to the right thyroid lobe. Thyroid U.S. indicated an uneven hypoechoic nodule in the right thyroid lobe and FNAC of this nodule pointed to a papillary thyroid carcinoma. A joint surgical process for resection of the thoracic and cervical tumors was carried out. After sternotomy, a large mass, having a diameter of a 35 mm was discovered at the back of the left clavicle and first rib, attacking the pleura and the left lung. A total thyroidectomy and cervical lymph node dissection followed the resection of this mass. The mediastinal mass comprised of a large lymph node having an undifferentiated tumor with numerous psammoma bodies on one side and on the other side foci of squamous differentiation. The diagnosis of a thyroid papillary carcinoma with attack of the thyroid capsule and a cervical lymph node was established; the mediastinal tumor persisted as a diagnostic difficulty, a dedifferentiated metastasis of the thyroid carcinoma was in all likelihood. For that reason, post- therapeutic scans indicated uptake in the thyroid bed and in the left mediastinum. At the final CT scan of the chest, progression of tumor in the mediastinum was present. THE TABLE&*()*))*)* Subject D A 52-yr-old women put before the hematology department for a follow-up visit. Morbus Hodgkin had been diagnosed for nodular sclerosing type, stage II B. with iliacal and inguinal lymph nodes. After six rounds of chemotherapy, which included Adriamycin, Bleomycin, Velbe, and Dacarbazin scheme, she stayed put in absolute reduction. Nevertheless 11 months following the preliminary diagnosis she complained of joint pain, particularly at the left hip and a FDG-PET scan with particular concentration to this area was ordered. It was negative with the exception of diffuse thyroidal uptake. Thyroiditis or attack by the lymphoma was suggested as the likely causes of the thyroidal uptake. On clinical inspection bilateral thyroid nodularity was detected and established by U.S.. FNAC of the right and left nodules indicated very cellular aspirates containing cell groups and handful follicles. A small number of mitoses were observed. A few atypical cells had an uneven lengthened nucleus, colloid was not present A small number of small and larger lymphoid cells were observed. The cytological diagnosis was follicular neoplasia and a complete thyroidectomy was carried out to rule out follicular carcinoma. The histologic diagnosis was follicular adenoma with Hashimoto thyroiditis. Subject E A 57-yr-old woman presented at the rheumatology department due to anemia, joint pains, and myalgia. She had refused invasive processes, and steroids had been prescribed for a resumed polymyalgia rheumatica, but upon narrowing the steroids the clinical picture depreciated with a toxic anemia (hemoglobin value of 70 g/liter) and loss of weight. Bone marrow target and biopsy were unconvincing. An FDG-PET scan was ordered to discover the primary location of inflammation or to spot a vague primary tumor. The FDG-PET scan indicated improved bone marrow uptake and a left cervical hot spot. FNAC of an hypoechoic nodule in the left thyroid lobe pointed to papillary carcinoma. Total thyroidectomy was carried out. The diagnosis of a PTC was ascertained. Even though small, measuring 13 mm in diameter, there was attack via the thyroid capsule in the strap muscles. Anemia endured, and a second bone marrow target and biopsy suggested the second difficulty: numerous myeloma. Subject F A 63-yr-old women presented to the oncology department complaining of low back pain in December 1999. Her past medical history comprised of a right mastectomy in 1988 and left breast carcinoma removal and adjunctive irradiation in 1996. Spinal MRI images pointed to metastatic lesions to the sacrum and the eighth dorsal vertebra. In the lack of proof of other metastatic lesions, an FDG-PET scan was carried out to ascertain the findings of MRI. It indicated a sacral lesion and an unpredicted right anterior cervical lesion. The patient was referred for FNACof an hypoechoic nodule in the right thyroid lobe having some microcalcifications. FNAC was poorly cellular and indicated sheets of distended follicular cells with large eccentric nuclei. Intranuclear pseudoinclusions were observed in some of the cells. A small amount of colloid was present. Cell margins were emphasized. The diagnosis of papillary carcinoma was put forward. Total thyroidectomy was carried out and final histology has been debated. Atypia, intranuclear pseudoinclusions, and nuclear grooves were there in some cells but were less prominent in comparison to the nuclear atypia in the cytology sample. Negative immunohistochemistry for thyroid peroxidase and positive immunostaining for HBME1 confirmed further the final diagnosis of a PTC. Subject G A56-yr-old man was referred to the pneumology department due to small peripheral lung nodules on chest x-ray noticed in the course of preoperative screenings for a hernia. A FDG-PET scan was ordered to find an unknown primary tumor or other metastatic lesions. A hot spot in the right lung top or anterior mediastinum was spotted. A thoracoscopic lung biopsy of the peripheral nodules was carried out and indicated varied dust fibrosis. The interest was then drawn to the thyroid lesion and the patient was referred for FNAC of an unpalpable retroclavicular nodule in the inferior right thyroid lobe. Cytology disclosed sheets and groups of Hurthle cells with a large quantity of cytoplasm, distended nuclei, and anisokaryosis. Colloid was profusely available. The diagnosis of follicular neoplasm, most likely Hurthle cell adenoma, was made. During this Hurthle cell tumor, surgery was considered and ascertained the diagnosis of a Hurthle cell adenoma. Subject H An 80-yr-old man was referred for examination of a large necrotic, pointing to a liver metastasis. Ten years before, in 1991 a left upper lung lobectomy was carried out for a squamous cell carcinoma. A FDG-PET scan indicated a hot spot in the liver and a second one in the right anterior cervical region. FNAC of a hypoechoic nodule in the right thyroid lobe was carried out: cell groups and some rosettes were there. The nuclei of the follicular cells were a little blown up A small quantity of colloid was available, and multinucleated giant cells and calcifications. It was categorized as a follicular neoplasm, most likely follicular adenoma. A liver biopsy indicated a large cell undifferentiated carcinoma. Immunostaining was positive for keratine and negative for thyroglobulin. The histology specimen of the lung carcinoma resected in 1991 was reworked and diagnosed as a well differentiated squamous cell carcinoma. The liver mass was thought of as a likely metastasis of the lung tumor. The thyroid lesion is left without treatment. FDG-PET method The PET imaging was carried out with a CTI-Siemens HR+ scanner (Knoxville, TN) having an axial field of view of 15 cm, and a spatial resolution of 6 mm. All patients fasted during 6 hours prior to the tracer administration. Sixty minutes after the iv injection of 6.5 megabecquerels/kg 18F-FDG with a possiblea maximum of 555 megabecquerels, a whole-body emission scan was carried out. The raw imaging data were recreated in a 128x128 matrix using an in-house iterative recreation algorithm without reduction correction. Discussion Eight successive cases of thyroid FDG-PET incidentaloma have been described. Ultrasound examination and FNAC were acquired in all, at this phase surgery and histology has been carried out in seven of them. The study suggests a high malignancy rate in thyroid PET-incidentaloma. Malignancy was accurately identified in five of seven patients in whom histology is achieved: two cases of MTC (subject A and B) and three cases of PTC (patient C, E, and F) caused focally amplified FDG-uptake in the thyroid area. In patient D, a lymphoma patient, the positive PET scan having bilateral and diffuse FDG uptake and bilateral suspicious FNAC were, nonetheless, because of thyroiditis additional to follicular adenoma. Diffuse thyroidal FDG uptake has in fact been explained in a cancer screening study in Japan in 0.4% of male and 8.9% of female subjects. In the 36 subjects having dispersed thyroidal FDG uptake in that study, it was credited to chronic thyroiditis. In fact, it was established by pathology in 2 subjects; in the rest, clinical follow-up indicated steady size of thyroid and in the majority antithyroid antibodies were positive (Yasuda et al., 1998). Severe thyroiditis is likely the most recurrent benign cause of diffuse thyroidal FDG-uptake, even though it can also be seen in Graves' disease. Independent adenoma can lead to focal uptake in circumscript hypermetabolic areas. In addition to a high malignancy rate, the current study also points to a high rate of clinically important malignancies; in other words, malignancies with an anticipated clinically relevant malignant biological behavior in the life span of the patient. Of the MTC cases, there was lymph node attack in one (subject B) of two. Of the three PTC cases there was attack of the thyroid capsule in two of them. Furthermore mediastinal lymph node attack having undifferentiated tumor, most likely dedifferentiated thyroid carcinoma was there in case C, and there was attack of the strap muscles in subject E. The high rate of thyroid malignancy and the high rate of clinically significant malignancies in thyroid PET-incidentaloma can be explained in two ways. The most palpable elucidation is the FDG-PET principle in itself. FDG-PET rather picks up malignant lesions due to the increased rates of glycolysis and glucose uptake. One of the glucose transport proteins, GLUT 1 has been found to be exhibited at high levels in a selection of cancers. By immunostaining, GLUT 1 expression was often visible in differentiated and anaplastic thyroid carcinoma, save for benign nodules or normal thyroid (Haber et al., 1997). Conclusion A conclusion has been reached by a number of authors that high FDG uptake in a thyroid tumor pointed to malignancy albeit low levels could not totally rule out malignancy (Sasaki et al., 1997). Next at this stage, histology is not taken in one patient with a follicular lesion. In wrapping up, but U.S. thyroid incidentaloma more often than not represent benign or occult malignant lesions, thyroid PET incidentaloma spot mostly malignancies having a predictable clinical significance rather than occult carcinoma. Potential FDG-PET studies considering quantitative or semiquantitative uptake parameters are essential to assess the factual occurrence and clinical significance of malignancies in this new category of thyroid incidentaloma.

How Retrieval Practice Strengthens Memory and Enhances Learning

Memory is not just about storing information—it’s about retrieving it when needed. Imagine studying for an exam and rereading notes multiple times, only to forget most of the material soon after. This happens because passive reading does not actively engage the brain in retrieving information. Instead, retrieval practice—a method where learners recall information from memory—has been proven to significantly enhance retention and long-term learning.

Retrieval practice and repetition go hand in hand, but retrieval practice has an even more profound impact on memory. When a learner is asked to recall information—whether through a quiz, a short simulation, or a gamified exercise—it strengthens the neural pathways associated with that knowledge, making future recall easier and more efficient.

In this article, we’ll explore how retrieval practice works, why it’s so effective, and how it can be incorporated into microlearning to create a truly powerful learning experience.

The Science Behind Retrieval Practice

When we learn something new, our brains create neural connections that store the information. However, if the knowledge is not revisited or reinforced, these connections weaken over time. This is known as memory decay, a concept famously described by Hermann Ebbinghaus in his "forgetting curve" theory.

Retrieval practice counteracts memory decay by forcing the brain to work to recall stored information. This process strengthens the "memory trace"—a pathway in the brain that connects to the learned material. The more often a memory trace is activated, the stronger and more easily accessible it becomes.

A great analogy is learning a poem. If you simply read a poem multiple times, you may recognize it when you see it again, but you won’t necessarily remember it word-for-word. However, if you try to recite it from memory, your brain works harder, reinforcing the connections to that information. Each attempt at recitation strengthens those pathways, making it easier to recall the poem later.

Why Testing is More Effective Than Re-Studying

Many traditional learning methods focus on repeated exposure to information—rereading textbooks, watching instructional videos, or reviewing notes. While repetition plays a role in retention, research shows that testing is significantly more effective in helping learners remember information.

This is because retrieval practice is an active learning strategy, whereas re-reading is passive. When a learner is tested on information—whether through a simple recall exercise, a quiz, or an interactive scenario—it forces their brain to retrieve the memory, strengthening it in the process.

Studies have consistently shown that:

Learners who take quizzes perform better on long-term retention tests compared to those who only review material.

Retrieval practice reduces the effects of the forgetting curve, ensuring information stays in memory for a longer period.

Even low-stakes or no-stakes quizzes—where performance is not graded—can dramatically enhance learning outcomes.

How Retrieval Practice is Used in Microlearning

Microlearning, which delivers short and focused lessons, is an ideal format for incorporating retrieval practice. The bite-sized nature of microlearning allows for frequent knowledge checks, which can take various forms:

1. Quizzes and Assessments

Simple quizzes at the end of a microlearning module encourage learners to recall key information rather than passively absorb it. Instead of just presenting the answers, questions should prompt learners to retrieve what they have learned.

For example:

Instead of stating "The capital of France is Paris," ask "What is the capital of France?"

Instead of listing the steps of a process, present a scenario where the learner must determine the correct sequence.

2. Gamification Exercises

Gamification—such as leaderboards, rewards, and challenges—can make retrieval practice more engaging. Interactive learning games that require learners to recall facts, solve puzzles, or answer rapid-fire questions tap into their competitive instincts while reinforcing memory.

For instance, a sales training module could use a gamified simulation where learners must recall key product features to "sell" a virtual product to a simulated customer. This type of recall-based exercise strengthens retention while keeping learners engaged.

3. Short Simulations

Scenario-based simulations force learners to apply their knowledge in a practical setting. These exercises can range from customer service role-plays to cybersecurity threat-response drills. By simulating real-world situations, learners must actively retrieve information rather than passively consume it.

4. Pre-Tests and Self-Reflection

A powerful way to implement retrieval practice is to use pre-tests—asking learners to recall prior knowledge before presenting new content. This primes their brains for learning and helps them recognize gaps in their understanding.

Additionally, encouraging learners to summarize a lesson in their own words instead of providing them with pre-written summaries enhances recall. Writing or explaining a concept in one’s own words is a form of active retrieval that strengthens memory retention.

5. No-Stakes Testing

One of the best ways to integrate retrieval practice into microlearning is through no-stakes or low-stakes assessments. These are quizzes or exercises where learners are not graded, but instead receive instant feedback. This reduces test anxiety while still reinforcing learning.

No-stakes testing allows learners to focus on improvement rather than worrying about scores. The key is repetition—bringing back previously learned content at spaced intervals to ensure it is not forgotten.

Combining Retrieval Practice with Spaced Repetition

While retrieval practice is highly effective on its own, combining it with spaced repetition enhances its impact even further. Spaced repetition involves revisiting learning material at increasing intervals, ensuring that knowledge is reinforced over time.

An effective retrieval-based spaced learning plan might look like this:

Day 1: Introduce a new microlearning module.

Day 3: Give a short quiz prompting learners to recall key concepts.

Day 7: Provide a brief scenario-based exercise requiring recall and application.

Day 14: Present another quiz or gamified challenge on the topic.

Day 30: Conduct a final knowledge check to ensure retention.

This structured reinforcement helps learners retain knowledge far better than a single learning session followed by no follow-up.

Real-World Benefits of Retrieval Practice

Organizations that integrate retrieval practice into their training programs see significant improvements in:

Knowledge Retention – Employees remember key concepts longer and require fewer refresher sessions.

Workplace Performance – Employees can recall and apply information more accurately in real-world situations.

Training ROI – Reduced retraining costs and improved learner efficiency lead to higher returns on training investments.

Learner Engagement – Testing, gamification, and interactive exercises make learning more engaging and effective.

For example, a healthcare company struggling with compliance training adopted a microlearning-based retrieval practice approach. Instead of long training sessions, they implemented frequent short quizzes and scenario-based exercises. Within six months, knowledge retention among employees improved by 60%, and compliance errors decreased significantly.

Conclusion

Retrieval practice is one of the most powerful tools in learning science. By requiring learners to actively recall information rather than passively reviewing it, memory retention is strengthened, and long-term learning is achieved.

When combined with microlearning and spaced repetition, retrieval practice ensures that training programs are not just informative but effective. Businesses that embrace this approach can expect a workforce that retains critical knowledge, applies it confidently, and performs at a higher level.

The next time you design a training program, ask yourself: Are your learners passively reviewing information, or are they being challenged to recall and apply it? The difference could determine whether learning sticks—or fades away.

It looks like those light-up patch cables you're using are the MyVolts Halos(?)

If thats the case, how have they been treating you? And does the visual feedback add anything to your workflow?

Well spotted! I actually have a lot of thoughts on them, so below the break:

The cables themselves feel very nice and sturdy. They have a nice ridgitidy to them, and I haven't yet had any fail in the two years or so that I've been using them.

The visual feedback is handy in some cases. I mute and unmute signals a lot as a performance technique, so it helps me keep track of which are enabled without having to look at the source and figure out which channel it is on the fly. This is especially relevant after a tidbit audio mute toggle (which I use in patches all the time and highly recommend) where I don't have any other indication of whether the switch is engaged or not.

Before I had an oscilloscope, they helped me learn more about how Cold Mac worked as well - if you have any complex modulator without its own LEDs, it can make them a whole lot easier to understand.

Now, for the bad:

While the LEDs do only use a little voltage, it can have noticeable effects. I wouldn't use them for a pitch sequence with a range over 2-3 volts, or I find the higher notes fall a little flat. Even for triggers, I've experienced issues with more sensitive modules like IDUM or Bard Quartet not accepting them. I also find that if I attenuate a signal pre-Halo, the signal will often not usefully light the LED, kind of defeating the purpose.

They also cause problems with some analog modules. Off the top of my head, my Maths functions often get stuck high if km using a Halo on the output.

TLDR, I think they're a useful tool to have in your arsenal, but I wouldn't want them to be my only cables. (and honestly, if your buying more expensive cables with extra features, I'd first opt for TipTop Stackcables.)
