this is a real shame about QY70/100: there's no midi channel on/off parameter. you have to enter a sysex message - thankfully pre-listed - in the Song mode, and 'run' the song to activate the message - and then you can go into Pattern mode and have your chosen midichannel outs turned off. ihaven't done this for a long time, and it's one of the reasons i'm more likely to use the RM1x these days (but still have a QY100).
i don't think there's any other way to do it? love to know if there is.
and... i was thinking it could be cool to do a Ctrlr panel for this and various other QY70/100 stuff ...
