The Cheapest Drum Module

This is probably the cheapest drum module available. It’s based on an ATtiny85 chip, the code was written by Jan Ostman and it’s open source. All you have to do is build it! Code: Build: pin 2 is the trigger input , pin 3 is a CV input (0-5V) for sample pitch control and pin 7 is a CV input (again 0-5V) for choosing the current sample. Pins 1 and 5 are not connected, pin 6 is the output, pin 8 is VCC (5V) and pin 4 is ground.
