The miniATMEGATRON is a sweet little digital synth by soulsby. A simple Arduino Uno is the core and with the shield, sold by soulsby, you can create a lot of cool sounds. A lot of parameters can be controlled by the potentiometers, buttons and some MIDI commands. The selection of waveform, filter etc. can be done by the four buttons (function +/-, value +/-) and the two RGB leds (D1 & D2). This is nice, if you’re just jamming.

For a better MIDI control, I added some more MIDI functions to the miniATMEGATRON libraries (edited: MinEngine.h & MinEngine.ccp) and created a Max4LIVE device.

overview (org. library midi commands):

  • PITCH ENV = CC# 94
  • PITCH LFO = CC# 1
  • LFO RATE = CC# 79
  • FILTER CUTOFF = CC# 74
  • FILTER ENV = CC# 16
  • FILTER LFO = CC# 93
  • FILTER Q = CC# 71
  • AMP LFO = CC# 92
  • PWM = CC# 91
  • DISTORTION = CC# 17
  • FLANGE = CC# 95

 

new midi commands:

  • LFO SHAPE = CC# 80
  • FILTER TYPE = CC# 73
  • AMP ENV = CC# 3
  • F/P ENV = CC#4
  • WAVECRUSHER/PORTAMENTO = CC# 5
  • VOLUME = CC# 120

 

To enable the new midi functions, follow the original steps by soulsby but use the modded library instead of the original libraries: soulsby instruction.
