Kickin' It: Crafting the Perfect Bass and Kick Groove!

Welcome to the world of groove! If you’ve ever tapped your foot to a beat, you’ve experienced the magic of a killer bass and kick combo. In music production, especially in genres like hip-hop, EDM, and funk, getting the bass and kick drum to gel is akin to pairing fine wine with cheese—one enhances the other. So, roll up your sleeves and prepare to dive into the rhythmic abyss as we explore how…

Binary Rounding

A small programming exercise:

Given a natural number n and a positive number of bits b, return the number m ∈ ℕ such that all of the following conditions hold:

m sets at most b significant bits.

|n - m| equals the smallest value of |n - k| ∀ k ∈ ℕ.

Additional information:

If a number can round to more than one value, return either value.

You may use bitwise manipulations.

Example 1

Input: n = 4, b = 1 Output: 4 (= 0b10)

Example 2

Input: n = 15, b = 2 Output: 16 (= 0b10000)

Example 3

Input: n = 21, b = 2 Output: 24 (= 0b11000)

Example 4

Input: n = 12, b = 1 Output: 8 (= 0b1000) or 16 (= 0b10000)

Sample solution below the cut:

Sample solution (JavaScript)

const solution = (n, b) => { const numBits = n.toString(2).length; const numInsignificantBits = numBits - b; const increment = 1 << numInsignificantBits; const mask = -1 << numInsignificantBits; const roundedDown = n & mask; const roundedUp = roundedDown + increment; if (n - roundedDown < roundedUp - n) { return roundedDown; } return roundedUp; };

Since, fundamentally, all physical things are quantized, they are all countable. We can dismiss the less vs fewer confusion by almost always using less.

i suppose a good love story will basically be relatable to all configurations of love between people. friendly romantic gay straight mono poly etc. but perhaps the greater love story will display relationships so idiosyncratic it could only be relatable to like three sickos (and they will be sickos) max

So I've decided to try something using my LittleBits Arduino bit and my LittleBits Adapter Eurorack module: the Dumbest Possible Quantizer.

(To overexplain, a quantizer takes a continuously varying voltage as an input and outputs a voltage that follows it, but in defined steps. The usual use case in Eurorack is mapping a control voltage onto the levels needed to produce, in the volt per octave tuning, a musical scale; you run random voltage levels through and get more musical results.)

Quantizer modules typically support different scales, modes, and keys, and sometimes even temperaments, but for the Dumbest Possible Quantizer, I'm limiting things to the bare 12-tone chromatic scale. And as suits the title, I'm doing this in the simplest possible way: I'm taking the 10-bit ADC value of the input — a number between 0 and 1023, covering from 0 to 5 volts — and mapping that onto the 60 midi notes that cover those five octaves. I'm then immediately turning around and mapping those 60 notes onto the 8-bit (0-255) value that the PWM "analog" output can take. This is nobody's idea of the proper way to do this, but since I actually had decent success using the second half as a USB MIDI to CV converter on this board already, it has a reasonable chance of approaching the desired functionality.

Long term, of course, I intend to build or otherwise acquire a quantizer module with real functionality, probably using a proper DAC; I'm following the in-development Teensy 4.1-based Ornament and Crime upgrade with great interest. But I really want to see how much I can do with very low effort!

Turning Digital into Warmth: Analog Vibes for Techno Wizards!

In a world dominated by ones and zeros, where digital precision reigns supreme, a new wave of techno wizards is boldly declaring that warmth is not just a feature of cozy blankets and good coffee—it’s a vital ingredient for music. Imagine a universe where the cold, sterile sounds of digital tools are replaced by the rich, organic textures of analog gear. As artists increasingly pursue that…

ALBERICH // RADIO OP [QUANTIZED ANGEL, 2019]

[wayti-blog]

"In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing Kelvin waves in superfluid helium-4.

First described by Lord Kelvin in 1880, Kelvin waves are helical (spiral-shaped) waves that travel along the vortex lines, playing a vital role in how energy dissipates in quantum systems. However, they are difficult to study experimentally.

Creating a controlled setting to observe them has been the biggest challenge that the researchers overcame. Phys.org spoke to the first author of the study, Associate Prof. Yosuke Minowa from Kyoto University.

The discovery came about through serendipity. "We applied an electric field to a nanoparticle decorating a quantized vortex, hoping to translate the entire structure. Instead, we observed a clear wavy motion of the vortex core, namely Kelvin wave excitation. This unexpected result prompted us to shift our focus toward studying the excitation of Kelvin waves in-depth," said Prof. Minowa."

Thinking about my analog bitcrush and sample & hold concept and I was wondering how I should order the functionality. I'm very much married to the name "Squish" and the answer just became obvious: Simple QUant Into S&H

Lucent Historia. Yes, a certain Rhythm isn’t here. That is bc drawing ‘em will require a lot more brainpower.

As for the second Lament Rain drawing and Astral Quantization… It is something I’ve been thinking about for while, which is that I’m not actually that happy about the character style of the current. So I might go full MLP EG and keep the colorful skin and make it clear to separate the skin & hair.

Anyways…

I’ve only mentioned it, but to elaborate when it comes to where Severed Eden/Lucent Historia lives…

You see, while Lasting Eden lives in the Arcane Towers, Severed Eden lives somewhere else.

Arghena, not rlly wanting to be in the same position as Tempestissimo (to not be under the watchful eye of Final Verdict), she decided that herself and her team should be somewhere right under their noises. Aka underground/underneath Fragrant Sanctuary. 

Originally called the Underworld, it is now known as the Parallel Palace; a quite literal mirrored/upside down version of the Anamnesis Palace. Mostly based on Ego Eimi’s part of the pack preview.

However, I would like to note that it was originally *just* the palace. No other buildings or structures. Cuz honestly, Severed Eden didn’t need much beyond that, as just having a place to stay/doing their own thing while being able to pop into FS at any time to do Guest Receptions was just fine.

Then a mysterious force (cough Lucent Historia) caused the area to expand, with lands thought to be unfamiliar…

With the Player hopping onto FS for the update, they find themself getting knocked out. Getting woken up by Abstruse Dilemma, the two take a look at where they exactly are, seeing Parallel Palace for the first time.

They were greeted by Primeval Texture, who assumedly thought that the Player knew of the place (they did not, PT is slightly out the loop on what is being kept secret), when the three were interrupted by a Rhythm- one only familiar to the Player- Swan Song.

Prompted by her, the Player and Abstruse Dilemma explore the Parallel Palace, as well as the recently created lands. Then shit hits the fan with the “true” Boss Song but that’s a story for later.
