Hi!

I've become so frustrated by this. I'm trying to control a virtual instrument with my Yamaha DGX-640 portable grand keyboard via USB connection. Pro tools lists it under Midi Devices (and in the Audio Midi setup on my Mac) but when I try to use it, no signal goes through. I have Midi-Thru turned on, and I got some release clicks a while yesterday, but now those clicks are gone and there is nothing coming through at all.

Please help!
