With os 1.23 and the previous non-beta OB it was possible to have the A4 (MKI) show up as a midi device while in OB mode and with INPUT/OUTPUT TO/FROM in the midi port menu set to USB.
Seems this is no longer possible which is a real shame because I like to regularly exchange sysex to backup sounds I’ve created and make backups etc.
Now I have to shut down Live, turn off the A4, disable OB engine, turn A4 back on, enable midi mode, trans/rec sysex and repeat the steps in reverse order.
Also seems if I don’t do everything in this exact order shutting down the OB engine with the A4 still on makes my computer (mbp with high sierra 10.12.6) crash instantly.
Not sure if this is the right place to mention this but I’m also with those who earlier said they preferred the old OB lay-out. Big fan of the new graphics and menu’s but the previous layout was a bit more efficient.
