Stepper

This is a 16-step sequencer and synth that I built with the Beaglebone Black and Bela board. It runs a Pure Data patch that reads 16 digital inputs for the sequencer steps and 8 analog inputs that control the synth parameters:

  1. tempo
  2. volume
  3. frequency of oscillator 1
  4. multiplier of osc 1 which controls frequency of oscillator 2
  5. attack
  6. decay
  7. polynomial waveshaper  for oscillator 1
  8. polynomial waveshaper  for oscillator 2 .
