When mapping sustain to Arturia Piano V2, my sustain pedal doesn’t work.
When I link it to other instruments, (swinging my midi connections over as a test in this in this test rackspace) it works.
I’ve tried deleting the Arturia Piano V2 plugin and re-adding it, different versions (VST3, VST, AU), physicallly restarting / reseating everything, and no luck.
Well, if you have defined both MIDI In blocks are OMNI then you need to have blocked all events except the sustain pedal from one of them and blocked the sustain pedal from the other one.
You should also insert a local MIDI Monitor plugin after those plugins to see exactly what is being sent to that piano when you press the sustain pedal
