When it comes to bindings. If the obvious fails I take a stab in every direction on the off chance that I’ll get lucky.
GVST’s little loop plugin is successfully remoted via note on bindings.
Now I want to use a MIDI controller which has transport controls where, surprise, surprise, record button goes red, play button goes green.
It’s a typical toggle switch affair, CCX 127 for on, CCX 0 for off.
I would’ve thought a ‘regular’ non expression binding would do it, but I can’t find a combination that does this, seemingly simple thing. I’ve issued the controller through every available connotation; switch, button, no edge etc etc.
The best I can do is a press to start, (LED ON) and then off (no impact on plugin) and then another press (LED ON) to stop.
So, it wants nothing but 127 to start and stop.
This particular hardware controller doesn’t allow toggle mode to issue anything other than 127 and 0 on each press.
Without using a filter to convert the incoming midi data, is there a binding methodology which could directly achieve this embarrassingly simple task?
Dare I put up the Bat Signal in the direction of @dave_dore ?
Hi Adrian,
Yes, a sticky wicket for sure but there is a way. It uses 2 bindings with the second binding set to a 100 mS delay. The idea is to fool the GVST looper transport into believing it is being triggered by a manual button press followed by a second manual button hence the 100 mS delay. More detail
first binding . Note the Looper VST is set to recieve MIDI triggers from a CC. The default was CC 80 so I stuck with it. The source uses a toggle switch and converts it to a variable controller. The mapping values for on and off are both set to 127.
The second binding is very similar to the first but the on and off values are both set to zero. Also a 100 mS delay is applied to the binding.
It works here using a control bar toggle switch I configured to CC 1 but I’m not sure how it will work with your controller surface. You may need to tweak it.

Dave, thanks for the creative thinking, as ever. To avoid multiple bindings I think I’ll sacrifice the toggle mode for momentary and keep the GUI open.
