How to connect Midi Devices to cSound in QjackCtl


This method has been tested under Ubuntu 12.04

Tools:
snd-virmidi: part of the Linux kernel
QjackCtl
Csound


Exposing virtual midi ports: 

sudo modprobe snd-virmidi

create a series of raw midi virtual ports visible in QjackCtl>Connections>ALSA 
tab in the format "XX:Virtual Raw MIDI Y-Z" where X, Y and Z are numbers


cSound <CsOptions>

+-rtmidi=alsa -M hw:Y,Z

Y and Z are the numbers visible in the QjackCtl>Connections>ALSA tab for the 
choosen port (see snd-virmidi ports created above).


Connect in QjackCtl the hardware port to the virtual midi port assigned to the 
Csound program.


That's It.
