Tested out the CVC connected to Osmose using the Haken Editor and CVC based presets that Expressive E provides in the Utility category. Here's a presentation on the fundamentals of using the CVC both in stand-alone default mode (options selectable in the editor) and programmed through the EaganMatrix.
Note that the Evaton Technologies "uCVC" also works if you are primarily interested in monophonic CVC connection (you can chain two together for duophonic operation) but that is not covered here as most will want to maximize using all four CVC channels with Osmose.
Note I also testing downloading Pitch Table Editor (PTE) tunings to the Osmose and they seem to work ok (though the editor is still visually geared for Continuum). So you can explore micro tunings and customer scales including importing Scala files on your modular setup using this connection though I don't go into great detail as PTE is its own video.
