I made a quick and dirty demonstration video so people can see what
PInstrument looks like. Hope this is useful.

> Hi, list. Thought some of you might be interested in this.

> I've shared my code for my PInstrument, a set of modules for audio
> synthesis built in Pure Data designed to run on a small touch screen.
> Specifically, the interface is designed to work on a 320x240 2.8 inch TFT
> Capacitive Touchscreen but it will work on any larger screen. The
> PInstrument is also designed to run on a low-power CPU like those in a
> Raspberry Pi 3 or 4. It was also designed with a 4in/8out DC-coupled
> interface to be used with a Eurorack synthesizer. As of 2021, Expert
> Sleepers produces both the ES-8 and ES-9 that will solve these purposes.
> I use it as a rack-mounted touch-screen in conjunction with an ES-8 to add
> functionality to my Eurorack setup without needing a big laptop on the desk.
> In it you'll find a number of modules:
> Relabi Waves - a four channel chaotic oscillator
> Turing Machine
> Phase Sequence
> Wave Folder
> VCA Panner - panner and four channel mixer
> Quad Cosines
> Clocks - a four channel clock-divider and clock-synced wave generator
> Drums - a quick and dirty set of synth drum sounds
> Pitch Tracker - three channels of pitch tracking for V/O control
> You can certainly run this wherever and however you want. You might even
> find some of the modules and abstractions useful. Using Eurorack has
> fundamentally shifted some of my approaches to Pure Data coding and I
> wanted to see what I could accomplish here. You can run it with Eurorack
> with Expert Sleepers or just run it stand alone on your computer.
> I believe it's all vanilla Pd. So there shouldn't be any compatibility
> issues.
> Feel free to fork or get in touch if you want to contribute. This is an
> evolving project, but I think it's reached a level of maturity that others
> might benefit. If you want help setting it up to boot from startup on a
> Raspberry Pi, get in touch.
> Cheers!
