Yes! A thousand times yes! Being able to switch the midi out (user) channel from the synth itself would be perfect to audition midi-synced gear with a thru-box. Even though I run my other gear with their own sequencers, not all of them have a keyboard. It would make the M2S the perfect control center and master clock for a small-ish desktop synth setup. Hopefully Arturia will include this in the next firmware, since it feels very much like an oversight. A shift-combo with the 1-16 pads (like the KeyStep/BeatStep controllers) would be perfect!
