Sorry for dumb question. How I can filter a control change messages entering a soft synth track?. Prophet 12 has an annoying feature that sends the midi cc7 when the volume  potentiometer is used. It can't be turned off without turning off all cc parameter sends.  


Thanks!. 

For playback try the MIDI Event Filter MFX or Edit > Select > By Filter
If filtering needs to happen while recording and turning off Controller data in SONAR Preferences is not an option; the data will need to be filtered before hitting SONAR with something like MIDI-OX.

There's also a CAL program called "Thin Controller Data.cal".    Post here again if you need some modifications to how it works. 

Thanks, I got it working now. I'm just jamming with newly purchased Omnisphere 2 and Prophet 12, so simple track midi fx was enough. I'm definately testing the other suggestions too. 
 
I haven't used Sonar that much, so everything is quite new to me. I'm more of a tracker guy (Renoise), but now i've finally decided to learn how to use Sonar proficiently.
