[Om-synth] midi control of effects

[Jake Michaelson]

Hi all,

First-time poster here.  I'm new to modular synths and MIDI in  
general, but am pretty literate in the world of Linux, etc.  I just  
bought a MIDI foot controller for my wife, hoping she could use it in  
her live acts (she sings/plays guitar) to control a live looping  
setup and also some guitar/vocal effects.  I already got the looping  
taken care of with SooperLooper and the MIDI programming/learning  
couldn't have been easier.  I've had a more difficult time finding a  
good setup for controlling effects.  I need a JACK-compatible system  
that can host LADSPA plugins as well as be controlled via MIDI.  Now  
my ideas of MIDI control are much more simplistic than most  
peoples'.  All the control I really need is to toggle between pass- 
through and effect-on.  I don't need any control over parameters -  
these will be pre-set.

I like om so far, but am unable to figure out how to accomplish this  
simple effect on / effect off control via MIDI within OM. I can get  
the PCM ins and outs connected with a LADSPA plug-in in between, but  
I don't know how to incorporate MIDI switching/routing to turn the  
patch on and off.

Can anyone give me some guidance on how to do this?

By the way, it seems that om can only read CC messages, it can't  
distinguish my PC messages (most of my pedals are PC rather than  
CC).  Is there any way to enable it to read ALL MIDI signals (PC, CC,  
notes, etc.), rather than just CCs?  This would help me get more use  
out of my pre-set pedals.

FYI I'm running om 0.2.0 under Ubuntu Dapper.

Thanks in advance!
