Question  Does the looping of Flashback X4  sync with midi I'd like to sync it to a drum machine loop. Is that possible Answer Unfortunately not. Flashback X4 looper cannot be synced to MIDI. It only responds to the start/stop/overdub switches.  Two features are available via MIDI:
  • Preset recall in Delay Mode 
  • Tempo Sync for the Delay time only. if a MIDI clock is sent to the input.
