It’s not the sound I want to mute, it’s the internal MIDI for the chord. I already have the sound set to off. But I have my VSTi (Lounge Lizard) that the output from scaler is playing.
I found info in this post which I thought might be the answer, but it messes with the MIDI coming into Scaler from Reaper.
