This might be more of an Ableton question. I have a Rev2 and an OB-6 hooked up to Ableton in the following config
Scarlett 6i6 MIDI out > Rev2
Rev2 MIDI out + audio > Scarlett 6i6
PC USB > OB-6
OB-6 audio > Scarlett 6i6
Rev2 and OB-6 are on different MIDI channels.
With this config I'm able to use the Rev2 as a MIDI controller for the OB-6 via Ableton, but the problem lies with when I start to turn knobs on the Rev2. Scrolling presets on the Rev2 also causes the preset to change on the OB-6, same with changing the master volume. Is there a way to set it up so that ONLY MIDI note info is sent to the OB-6?
EDIT: I figured it out - just had to disable MIDI prog send and MIDI parameter send from the Globals menu on the rev2. Thanks anyway!
