Vintage Synth Repair

Hi,
Looking at the supplemental material,
Does your Source have the updated rom and inputs?
Your arp an sequencer can run from a sync from
a drum machine. If the Source things there is 
a drum machine connected, it may be waiting for the clock
from it.
The din socket will say "SYNC IN" below it.
I would check the associated circuit with this.

Hope this helps.
