  1. Has anyone taken one apart yet? I wonder if that keybed has a separate circuit board from the rest of the unit. Would love to buy one and make it into a desktop synth.

  2. This to me is one of the best sounding synths of a lot of years, It has a serious sound palette. Looking forward to getting my hands on it.

  3. I’m mostly excited about the sequencing it can do.. Wondering Arturia will mesh that in with newer controllers like a Keystep Pro / Beatstep MK3. I really hope an update allows for layering 2 or more of the synth engines, then this thing would be a beast!
