Lewis - Retrospective Notes from The Nashesizer meeting on 6th November 2017, 4pm Salford Eagle Labs

Present: Lewis, James, Mike + Craig - Gemma came along to the DM Lab North meet up later on.

Development Notes

Everyone is generally happy with ‘The Nashesizer Development’ document Lewis worked up for Gemma and Nicole Rochman at Sound and Music - including the proposed schedule, allocated days per team members and overall budget.

Introduction

We discussed the prototype developed through the Drake Music Lab North West Challenge - detailing what worked, what didn’t and what we’ve learned through the process - then outlining ideas for next stage development. Lewis later summarised key points for Gemma and got her feedback and input.  

Joystick

The principle of using the joystick as a key navigation mechanism within Ableton Live seems to work and make sense for Gemma. The prototype and its associated default Ableton Live file (including all the relevant MIDI mappings) enabled movement left and right between tracks and up and down between controls (volume, pan, aux sends 1-4 etc.) in Live’s ‘session’ view. The next iteration should also allow similar navigation between audio/MIDI clips within Live’s ‘session’ view and perhaps also by marker and track in Live’s ‘arrangement’ view.

Gemma likes the arcade joystick - even though and perhaps because it’s large and basic and so easy for her to use. However, this means that any 3D printed casing that accommodates the existing joystick will also be relatively bulky.

James did attempt to deconstruct and adjust the height of the shaft for the prototype - but despite being a relatively simple mechanism with four microswitches it’s actually well-designed for purpose and not straightforward to adapt.

Generally the thinking is that we should stick with this type of joystick - Gemma agrees she doesn’t have the fine motor control to make effective use of a progressive joystick or one with a higher number of (up to 8) positions.

It would be worth looking at slightly smaller alternatives - such as this Small Arcade Joystick via Proto-Pic or more ergonomic and compact designs such as this APEM 100113 2-axis, 4-position joystick via Farnell.

Lewis has since found single axis joysticks - such as this Penny & Giles JC100-002-5K via Farnell - which although quite expensive (£42.39) may well suit Gemma and be worth trying out.

Motorised Fader vs Rotary Encoder

Apart from the joystick, the prototype incorporated both a chunky (and particularly high resolution) 1024 pulse per rotation, quadrature rotary encoder and a 100mm motorised fader.

The key thinking here - in part based on Gemma’s feedback of her Akai Pro MPK mini mkII - was that a controller with multiple knobs and small buttons didn’t really suit her. What she needed was an alternative method to the track ball to navigate quickly to a given element within Live she wanted to tweak (via the joystick) and then a single fader and/or knob that worked well and was easy for her to control to adjust the value.

Lewis’s initial thinking was that the fader and encoder should be effectively interchangeable - having navigated to a specific control in a given track using the joystick, Gemma could then set a value with either the encoder or the fader module and the other module would update accordingly. In practice this didn’t work out - in part because the two modules were developed separately (the encoder by Lewis and the fader by Mike) but more significantly sequentially - one after the other. Accordingly the code developed for the early Teensy master and module slaves was a ‘rapid prototype’ and integration of the final set of inputs was somewhat bodged - they got caught in a feedback loop that was never really resolved.

The upshot is that we’ve now reconsidered this initial approach - while the next version will likely include multiple inputs, they won’t be interchangeable. Each input module will likely drive a specific and consistent control/element within a track/clip.

We’re also going to design the core code for both the master and slave devices to be far more robust and extensible. Mike’s suggested a ‘cooperative system’ approach in which each module within the overall design is part of a sequential state machine but with a secondary feedback system so that each is allocated the appropriate time it needs to complete its task.

These issues aside, Gemma also likes the fader far more than the encoder - which despite it’s high resolution, size and 3D printed custom knob she still found difficult to use. We thought that making a single large encoder with an ergonomic knob would overcome how fiddly Gemma finds arrays of small, close packed knobs on commercial controllers. But on reflection it seems to be more about Gemma’s restricted movements - she actually finds the wrist/whole hand twisting action required to turn a knob more difficult than say the combination of thumb/first finger movements required to control a track ball or the single finger/whole arm movement required to move a fader. We didn’t appreciate this initially and needed to build the prototype rotary encoder module to find this out.

This thinking will have an impact on our choice of future input modules. The Korg nanoPAD2 and microKEY Craig selected during the prototype phase, provide Gemma with a very suitable MIDI keyboard and XY-pad and buttons - so we don’t need to duplicate these. Motorised faders do seem to be a good choice - albeit that we need to control when they update so that they’re not in constant motion as Gemma moves between tracks (a simple timeout between a track change should sort this).

Lewis suggested we should buy and hack a used Behringer BCF2000 MIDI controller which has 8 motorised faders (~£120 second hand via eBay). From a Google image search it looks as though the faders and adjacent right hand side button bank are on a separate PCB to the top set of encoder knobs and buttons which also makes the possibility of adapting and rehousing these faders more likely. Even if we end up desoldering the motorised faders from the PCB it’s potentially a cost effective alternative to buying new components.

Isotonik Studios have a series of M4L control surface scripts and automapping utilities which integrates the BCF2000 into Ableton Live and are worth investigating further.

We’re also planning to test an alternative rotary encoder set up where the encoder is turned through 90 degrees - essentially providing a rotating disk or one-axis track ‘wheel’ which should suit Gemma better. These can be standard 24 pulse per rotation quadrature rotary encoders - far cheaper and more compact than the encoder from the prototype. We’re also going to try mounting the encoder on a bearing so that the angle of the wheel can be adjusted to best suit Gemma’s hand position and thumb and finger movements. Choosing rotary encoders with an inbuilt ‘click’ should also make using them more ergonomic and haptic.

Other input modules

Additionally we’re thinking about testing and integrating a distance/capacitive sensor for gestural control and an Adafruit 3.5" TFT 320x480 + Touchscreen to provide not only a larger on device display than the prototype (a late addition to the initial design this actually worked very well) but with the potential for an additional yet simple touchscreen interface.

We also discussed integrating a basic set of transport buttons into the controller - play, stop/pause and record - so that Gemma can control Live’s playback and record functions from the device itself.

A modular system

An initial conception for The Nashesizer was that it be modular - a ‘base’ board with a set of independent modules that could be rearranged and reconfigured for different uses. While the prototype did realise this approach to some extent - the Teensy 3.6 in the base board acts as the I2C master with an Arduino Nano inside each module as I2C slave - the engineering required to fabricate a robust but flexible connection system between base board and modules was just too demanding. We’ve since decided that ‘modular’ in this context means configurable during fabrication - the layout of the various input modules integrated into The Nashesizer can be customised for Gemma’s preference while it’s being built - but once fabricated modules will be essentially fixed and can’t be reconfigured.

One issue with the prototype was power requirement. The relatively large current demand of the motorised fader (~0.6A) meant that the OLED display frequently didn’t work when it was plugged directly into a laptop USB port (which conventionally only provides 500mA). The solution was to use a powered USB hub with a 1A port - fine for a permanent home set up but not ideal in a live setting requiring more kit, cables and power sockets. Mike has since suggested we integrate a 12V PSU into the next version and step-down convertor(s) to adjust the voltage to the required values for all of the various modules and components.

The prototype is currently connected to the computer via the Teensy’s micro-USB socket. This is fiddly to plug in and not robust - the socket has developed an intermittent fault due to the strains of continual plugging and unplugging. So we’re going to integrate a far more robust USB A type socket into the device and then connect this internally to the Teensy’s micro-USB socket.

Gemma and Ableton Live

Gemma currently uses and is familiar with PreSonus’s Studio One. However, she’s agreed that The Nashesizer should be aimed at Ableton Live which she also owns a copy of and is keen to get more familiar with. So a key aspect of the project is for her to shift to working in Live and to develop her understanding and abilities in using it. Craig will support Gemma through a series of ongoing one-to-one sessions to get to grips not only with it’s functionality but also it’s creative potential.

Next Steps

Lewis to upload these notes to the project Tumblog and invite feedback from the team. Then to arrange one-to-one meetings with team members to discuss and plan next steps.

Please add comments and additional things we discussed if I’ve omitted anything or gotten the wrong end of the stick.
