  Hi,
 I am thinking about adding midi or/and osc support to Jackbeat
 (
http://xung.org/jackbeat). My idea is to use a hardware midi controller such as
 the evolution uc33 to control pitch, volume and muting on every tracks. This
 would help using Jackbeat for live performances.
 I have never coded with midi, neither with osc. What's the fastest and smartest
 way to achieve this idea ?

The best ALSA MIDI reference I found was 
http://www.suse.de/~mana/seqdemo.c
It's an example client that illustrates how to receive MIDI messages.
It should be pretty clear how to add MIDI control after you look at
that code.
