I've never actually used M-Tron Pro (I'm not a great one for softsynths), but reading the documentation on GForce's site, it does support aftertouch to modulate the filter and lots of Continuous controller messages to do other stuff. It woulf be trivial for GForce to add support for polyphonic aftertouch, so that anything you can do to the sound globally via aftertouch or cc's, you could do to varying individual amounts on individual keys with poly aftertouch. Sounds like they're missing a trick there. David
