Arduino based multifonction Eurorack module

This is an Arduino based multifonction Eurorack module from Cavisynth.
It has 8 different functions, all are based on the square wave:

• Trigger (2 to 100ms by pulse) by push button
• Tap-tempo trigger (2 to 100ms by pulse)
• Modulator (voltage controled) - ( frequency is fixed between 0.5 Hz (2000 msec) and 15 Hz (65 ms))
• Square VCO (normal mode or gate releasable)
• Complexe square 1 (normal mode or gate releasable)
• Complexe square 2 (normal mode or gate releasable)
• Noise
• 440 Hz tuner

This versatile module Eurorack format is unique and different from its design and functionality.
The summer development philosophy from a single strain, the Arduino board (compatible) ProMini based ATmega328P microcontroller and draw the most obvious and useful features. The main constraint is best that one can not draw as digital or square wave signals. What makes that all the "outbound" functions are based on square wave.
What's great is that through Arduino you can reprogram yourself this module to your liking and add or modify existing functionality as the code is open-source. Simply program the Arduino and a FTDI interface.
What you have purchased (at a low cost, you will admit) is the hardware, the module mounting and development.
It is also the first official unit out of the labs Cavisynth. First of many hopefully!
