Hi @Neiljohnson. Welcome to the Scaler Forum. I actually haven’t tested Scaler’s Multi-Voice Output with Pro Tools. It works natively with most DAWs, the main exception being Ableton Live.
What trouble are you having with Pro Tools? Is it related to use with mono-timbral plug-ins, or multi-timbral plug-ins? Or both?
If Multi-Voice Output simply isn’t working with Pro Tools this is something we’ll need to mention in our reference document (which I assume you’ve seen: Scaler 2.7 Multi Out, how to guide and information for various DAWs), but it would be worth seeing if anybody else here on the forum has had any success with Pro Tools and MVO.
