Megadrum Diy edrum module

I know this not related guitar but this is a great dsp diy project to build. Many guitarist also do drums, so it might interest them.
It was my first dsp project.

Here are the main features of the MegaDrum drum trigger

   * Atmega based. You can choose Atmega8 (obsolete), Atmega32, Atmega324P or even Atmega644. Several versions of firmware are provided for 12MHz, 16MHz or 20MHz versions of these chips.
   * No need for an expensive programmer. Programming is done via a simple cable.
   * MegaDrum firmware can be upgrade over Sysex so you won't need a programmer after an initial bootloader firmware has been programmed.
   * USB powered. No need for a separate power supply.
   * Different MIDI I/O options: standard MIDI or one of optional USB Boards: PIC18F2550 true USB MIDI, USB over FTDI232(obsolete), USB over AVR-CDC (obsolete,Atmega8 based)
   * Potentiometers free design. You don't need pots at all and this saves quite some money.
   * 9 levels input gain set individually for each channel.
   * Supports Dual Zone Piezo-Switch pads.
   * Supports 3 zone Roland style cymbals (e.g. CY-12/CY-15).
   * Sopports 3 zone Yamaha style cymbals (e.g. PCY150S).
   * SysEx support. MegaDrum can be controlled from a computer.
   * 4 Crosstalk suppression groups with individual crosstalk suppression levels in each group.
   * Can save 2 or 4 configs and 7 or 13 Drum Maps (depending on the MCU type).
   * Individual midi channel, dual/single pad, auto/manual sensitivity and curve settings for every channel.
   * Velocity curves for each individual channel can be compressed and shifted.
   * CC Choke support on every Dual Zone piezo/switch pad or 3 zone cymbals.
