[AVR] USB MIDI Drum Trigger based on AVR and V-USB

[wzab]

Hi,

I have just finished and successfully debugged a cheap and simple
USB MIDI Drum Trigger, which I've built for my sons:
http://www.ise.pw.edu.pl/~wzab/MIDI/perkusja/index.html

To keep costs as low as possible, the design is based on the ATmega88
with firmware based on V-USB-MIDI ( http://cryptomys.de/horo/V-USB-MIDI/index.html )
The PCB design is also as simple as possible - single-sided, wide tracks,
DIP and through hole components, well suited for thermotransfer technology.
Complete KiCad ( http://kicad.sf.net ) project is available.

The trigger implements a USB MIDI class device, so it should work with
different applications and different operating systems.
My children use it with hydrogen (http://www.hydrogen-music.org/ )
and lmms ( http://lmms.sf.net )

I hope that my design may be useful for someone. Everything is open source
or public domain.
