Identifying FM chip used in a Yamaha keyboard (DSR-2000)

Postby lukeoftheaura » Mon Mar 27, 2017 11:07 am

Hi,
I have a Yamaha DSR-2000 synthesiser/keyboard, and I'd like to identify what FM synth chip it uses, preferably without disassembly. I know it's 4 operator and seems to have more than 10 voices, but nothing else beyond that. Any ideas?

This page is a comprehensive list of Yamaha chips and what products use them.

My guess is this one:

YM2414(B)
(XB768001)
OPZ
"OPZ Operator" Excellent Sega Megadrive-ish tone generator. Requires external DAC - YM3012. Electone HS-8 has five of these inside (besides GEW1). DSR-1000, DSR-2000, DX-11, EW-20, HS-5, HS-8, PSR-80, PSR-90, PSR-6300, TQ-5, TX81Z, YSS-100, YSS-200
I listened to Hatfield and the North at Rainbow. They were very wonderful and they made my heart a prisoner.
