Controls and Audio

• Main knob -- controls wavetable position

• X knob -- controls amount of triangle wave LFO to add to wavetable position

• Y knob -- controls frequency of wavemod LFO

• Z switch down -- selects next wavetable

• Z switch up -- toggles quantized notes or not on CV 1 Input

• CV 1 In -- pitch (0-5V) should kinda track 1V/oct, with nothing plugged in note = 36 MIDI

• CV 2 In -- adds to main knob to control wavetable position

• CV 1 Out -- reflects current wavetable position

• CV 2 Out -- reflects wavemod LFO

• Pulse 1 & 2 Out -- PWM audio out

Pre-built UF2

• See build directory for a UF2 to copy to RPI-RP2 and you're off!
• Also availble at https://github.com/todbot/Hello_Computer/releases/

The prebuilt UF2 contains the following wavetables:

• PLAITS02.WAV -- Wavetable from Mutable Instruments Plaits
• PLAITS01.WAV -- Wavetable from Mutable Instruments Plaits
• BRAIDS01.WAV -- Wavetable from Mutable Instruments Braids
• BRAIDS02.WAV -- Wavetable from Mutable Instruments Braids
• BRAIDS03.WAV -- Wavetable from Mutable Instruments Braids
• MICROW02.WAV -- "A curated set of wavetables from the Waldorf Microwave 2"

Setup if not using the pre-built UF2 file

1. Install MTM CircuitPython UF2 from https://github.com/todbot/circuitpython/releases

2. Copy the mtm_computer.py file to the CIRCUITPY drive.

3. Copy the code.py and wav directory to CIRCUITPY drive.

4. Install the extra CircuitPython libraries with circup install -r requirements.txt

5. Can use any other WAV wavetables from waveeditonline.com including other Plaits, Braids, and PPG wavetables, just drop them in wav. The order they come up in the oscillator is based on their names.
