Hi there -- I'm testing the demo of the Prophet-5 V, and I can't get MPE to respond.
I'm using Ableton Live 11 with an MPE controller (qunexus).
Other soft-synths are responding to MPE y-axis (cc 74) just fine in this setup, e.g. Ableton's 'wavetable' instrument, as well as Roli Equator.
When I configure MPE on the Prophet-V demo settings to connect "MPE Slide 1" (cc 74) to filter cutoff, nothing happens when I do the slide.
Is it possible that MPE is simply disabled in the demo mode?
