I'm using the demo SEM V, and I've tried the Modulation Matrix: Source: Mod Wheel for Destination: Vibrato (LFO 1), but the Mod Wheel/Joy stick for modulation, or pitch bend never seems to work. Any solution to this, or anyone having the same problem with an external MIDI (mine is a Korg DS-8) keyboard? iMac OSX 10.6.8 with Cubase LE4.
