I've just updated TenCrazy.com MFX CC Map to v1.3.
Now you can also manipulate Channel Pressure/Mono-Aftertouch messages. Handy!
To people without MFX-capable hosts: sorry! Hopefully your host can do this natively (I hear there's nothing Macs can't do anyway ). We'll also try to find a non-MFX solution for you in the future.
