Hi Noel, thanks for the suggestion. Just tried testing with the Coyote WT, along with retesting the TTS-1 and the SFZ as well (just for testing this function - I understand SFZ is not multitimbral). I had the GS Wavetable chosen (your Step 2). Now the appearance of the GM2 popup - ie. normal behavior - is more frequent, but for all three synths, there was an occasional string of 3-4 non-appearances before the functionality "reset" itself to normal.

From my (hobby) programming experience, the behavior is reminiscent of failure to trap a timer on some internal process when it exceeds a preset limit. Sorta like a machine trying to cap a bottle when the bottle has been delayed reaching the capping point on the conveyor belt.

Whatever the cause, I'd guess this is not likely to get much attention, because many users nowadays don't seem focused on midi, much less higher banks. Sigh.

I'll notify support if it actually becomes bothersome.

Thx, -Ron

PS. More troubling is the apparent failure of the "thru channel always active" feature, as noted in another thread. Will get to your suggestion there in a day or so. Today is football and gift wrapping. smile BTW, happy holidays to all!
