I have invested a lot in hardware lately and a Korg SQ64 sequencer for getting short ideas down, instead of bringing my MBP down to my studio and fire up Cubase every time.
This is a great setup, because after I flick the first on/off switch on my gear it takes about four seconds before I am ready to play and record.
Thus all my external gear is synced to the SQ64 tempo whenever I am DAWless.
But what I really would like to do is also sync Cubase to the SQ64 so if I launch Cubase to play a VST, the VST arp (or drum track for that matter) is synced to the SQ64’s tempo.
I searched the Cubase manual but as far as I can tell it mostly focuses on syncing external gear to Cubase.
Back in the day (1980’s, Atari?) when Cubase was a MIDI sequencer, it used to be possible to be clocked externally. Now, with audio, Cubase must always be the master MIDI clock.
