I switched my DAW to ableton the other day and am having some strange issues when connecting my Voyager up. If I run a midi clip that feeds into the Voyager, it runs fine until I click anywhere on the screen and then suddenly the notes playing drop an octave. This happens no matter what I do. Obviously Ableton is sending a midi message to the voyager, but I don’t know why. I have disabled the Midi input on the track too…
Is it doing this in any project you open in Live, or just the project you’re working on?
I’ve had similar issues emerge mysteriously in the middle of a project, I wound up cutting-&-pasting the midi info into new clips in a new project. This seemed to work for me. Hope it helps. Good luck.
