Thank you , Promidi. I checked and re-checked your list:
In preferences - MIDI - Devices your MIDI port that the Motif XF is connected to is present and enabled. I have the MIDI driver set correctly. It's all been working perfectly other than the MIDI signal being received. In preferences - MIDI - Playback and Recording - tried both MME and UWP (I find MME to be most reliable) The YSFW driver is what I use (the MME is greyed out). Set your MIDI track's input to the MIDI port that the Motif XF is connected to. I checked track-by-track to make sure. All MIDI channels set to 1, (Motif XF, MIDI track input. MIDI Track, VSTi synth - or at least to Omni ) Because of recording to/from the 16-track sequencer I have to assign each track to its own channel which all works perfectly, until this glitch occurred.
Local Echo on Check. All volumes up Check No Controller events turning down volumes in MIDI track Check.
I just don't understand why the computer plays and receives 16 tracks simultaneously, but the keys aren't received any time (except in all the other apps).
These all are excellent ideas. The condition didn't improve. It's something else, yet. Hmmm. Thank you so very much for putting the time in to help me out! And, thanks for the MIDI Monitor tip. To my amazement, I had the box checked already, but nothing in the system tray I'll check that out, too. I appreciate it all!
