It’s still an option to sync Midi time code on a hardware recorder, or, go the whole hog, get a Zoom Livetrack, which are brilliant, and use CV and sequencers to record your synths.
Are you saying it is possible to somehow capture MIDI data for later editing with the Zoom? (I don't think so, but excuse my ignorance.). If so, I'm sold - I too love the Zoom otherwise!
