HI, there.
I have own one of your 32 Inputs Megadrum, Atmega644 based at 20MHz, you have build to me (Thanks by the way Dimitri).
My megadrum dates is from July 2010 i have loaded the last firmware megadrum_20120415.
But, now i just have realised that from 11 input to 17 My megadrum is not receiving hits or data. 1-10 inputs are working normally.
I wish you can help me. Maybe i am doing something wrong.
Thanks in adavance.
