i have found another error that is similar so i thought i should just re-visit this post rather than posting a new one. if i midi map a knob to the preset bank controls, the knob only works when you are in the effects preset tab. when i switch to Transitions, Text Overlay or Image Overlay, the knob that i set to the preset bank does not respond even though the preset bank controls are green and show the correct CC control # for all 4 preset tabs (the knob still changes the preset bank of the Effects tab though). Also, the Quartz Overlay tab is different. the other tabs seem to share the same preset bank control and all turn green when mapped to a knob. the qc tab is independent of the rest and i can map a diferent (or the same knob) and it works as expected.
