I upgraded to 4.61 and installed the latest MIDI drivers from the MOTU site, and my MIDI function has gone away. I can't trigger hardware or software MIDI from my keyboard controller (Fatar Studio 900), although existing MIDI info in the sequencer will play back. I see the MTP/AV MIDI light turning on when I play the keyboard. I've jiggled the cables. Also, it screwed up my PCI-424 settings - I had to reset my inputs/outputs , my digital i/o were missing. I actually went back to DP 4.52 but that's not working either. I checked the audio/MIDI setup and set I did notice that the MTP/AV is "grayed out", but I have the latest drivers, so I don't get it. Any ideas?
