I was in need of a good audio processor, something like jack-rack. The problem with jack-rack was that I could not change a control in the logarithmic way with my external midi device. At last, now it's possible with the 'om' synthesizer. Now I can use Linux as a DJ effects processor!
Great!
It looks like om-synth listens only to midi channel 1. It would be cool if one could change it to another midi channel.
