peter Agreed. It should be available on a "per assignment" basis. In a similar fashion to the "Stop Button Mode" where the user can select between Pause/Rewind/Next, have a selection choice appear when a controller is assigned that allows selection between Momentary/Toggle
Why not reconfigure my controller? Because I would have to go through 5 years of songs on a song by song basis to change my controller settings in Gig Performer. I work as a music minister and program 6-7 songs per week, 52 weeks a year. So switching to momentary mode would require me to reprogram 1684 songs. This doesn't make sense to me when it's clearly possible as a software setting.
The controller not only toggles playback for me in GP, it automatically changes mic mutes, turns on reverb and changes other parameters for my guitar and virtual instruments, essentially toggling between a performance mode and a talking mode - which is why it made sense to configure my controller to toggle A/B with toggle mode.
