Korg Volca FM and Tascam DP 006 Sync

I recently got a Tascam DP-006 digital four track recorder. This is my attempt to use it as a sync source for a Korg Volca FM. The same basic technique could be used with other hardware. This is my first attempt at a video tutorial; please forgive my cinematography and editing! Same technique should work with Tascam DP-004 and DP-008; the general idea applies to any multi-track recorder.
