According to the manual CC1 is assigned to emulate exp 1. Mod wheels send CC1. So not a bug unless it's responding to messages from the wrong channel.
Which reminds me that I think there's a bug in the HX ONE. It seems to actually respond to CC1 from any channel despite the channel setting. So if I have it hooked up via MIDI and I move the mod wheel on my keyboard, I get an ultra rapid fire bypass. Haven't tested more, because it's the only device that will respond to the wrong CC1.
Yeah. I figured that out. Seems weird to me, but I changed the MIDI channel on the Stadium, and all is good there. But I can't figure out how to change the listening channel on the GM-800 or change the CC the modulation wheel is sending, so it's changing the volume and other settings on the GM-800 that I don't want.
I guess I never used the modulation wheel on my previous keyboard.
