Had a think on this today and remembered that the GCP only allows a single CC command per switch, so you will need to dedicate 1 switch to bypass the TimeFactor if it is on a separate MIDI channel….. Otherwise it will get complicated to program.
Is the TimeFactor on a unique midi channel?
If / once it is the program one of the IA's switches to send the CC number you set on the TimeFactor for Bypass on the unique Chanel that the TimeFactor is on… As long as the TimeFactor is listening on that Channels and nothing else is ie other things are not set to omni… All channels. You should be good to go
