Vintage Synth Repair

woohoo! just scored an mg-1 at a yard sale. after a heart attack and 
some rust removal, it and i appear to be working fine. i read in a 
user review(at synthmuseum, i think) that an external souce could be 
sent through the filter(like the korg x911, i assumed), but i have not 
found this to be so. is it so? the rca inputs, i realize, just go 
straight to the outputs. also checked out the synhouse midijack for a 
midifying solution. is this the cheapest way to go for basic midi 
control? i have a tb303 and a drumulator modified for roland sync 
compatability, but i don't think they will work with the mg-1. would 
someone explain the cv and trigger inputs and what type of units 
should work with them. better yet, does anyone have a user and/or 
service manual to share?

many thanks,

shayne

apologies if i sound impatient, but i'm just excited to get this thing under some kind of remote control. there must be someone here in possession of mg-1 esoterica. i'm going to try this:
tb303 audio out > korg x911 audio in > x911 cv out > mg-1 cv in.
