SY77 Refurbishment

Yamaha SY77 is a 16 voice multitimbral music workstation first produced by Yamaha Corporation in 1989. The SY77 is a synthesizer whose architecture combines AFM (Advanced Frequency Modulation) synthesis, AWM2 (Advanced Wave Memory 2) for ROM-borne sample-based synthesis, and the combination of these two methods christened Realtime Convolution and Modulation Synthesis (RCM).

SY77 Refurbishment

Unread post by sonic2000gr »

I just finished with my SY77 refurbishment, and would like to share some useful info:

- In page 7 of the SY77 Service manual you can get (if you are patient) all the cabling destinations from one board to another. For anyone who is not patient enough, this is it:

Code: Select all

Board: PNAB (Voice buttons etc)

CN1 => PNC CN8
CN2 => PNC CN7
CN3 => JKAN CN3
CN4 => DM1 CN117

Board: PNC (Encoder, LCD buttons etc)

CN10 =>  DM1 CN112
CN5 =>  DM1 CN110
CN6 => DM1 CN108
CN9 => DM1 CN102

Board: LCD
