Its a Synth made during KYTA 2017 at Kalga as part of Residency for a new notional experimental quadraphonic audio environment in the Himalayas.

The facility will be open to experimental sound artists from the summer of 2018 as a making, listening and hacking space. Check the making and the story behind this on youtube

Modified slightly the code by Tim Barrass using Mozzi library

This built demonstrates analog inputs from 16 channel multiplexer «CD74HC4067» and control oscillators, phase modulation and smoothing a control signal at audio rate. Also demonstrates AutoMap, which maps unpredictable inputs to a set range.

Mozzi CD74HC4067

This Panel of Knobs enables oscillators and the control modulation.

Cosine wave table is used and the freq range is 8hz to 8184hz While the control-modulation is 0 - 127

Use this Code in Various permutation changing the analog input for oscillators and control modulators. 3 Nano + Mux, 3 Leonardo + 2 Mux and One Uno along is being used in the Panel.

Only One Leonardo is sufficient for the design with Mux used as input for mux and get all the potentiometers into one Leonardo. Doing that was making the control oscillations clicky and buggy as ATmega32u4 is not able to process 50+ simultaneous oscillators.

Panel.dxf can be used to replicate the design using Laser or CNC.
