I understand that this is probably a pretty elementary question...

...But I recently purchased a 727 and was hoping to connect it (via
any means possible) with my 707 to run the two simultaneously and I
have absolutely no idea how to go about doing this as I understand
very little about MIDI, DIN Sync, etc.

If someone could merely point me in the right direction, it'd be more
than greatly appreciated.

Thanks.

Sincerely,
-Wes
