Scaler 2 is in the MIDI channel’s effect chain, as it should be, Ableton says it is sending MIDI to Scaler 2, but Scaler 2 is not detecting it. No sound, the keys in the app are not highlighting either. Scaler 1 works fine.
this has been reported by a few people, is seems to go away after a reboot. If it doesn’t solve the issue, try reinstalling the latest version then reboot after install.
Let me know if that helps,
I’ve already tried both of these
