[sdiy] VSS 200

[Jerry Gray-Eskue]

Hi everyone,

I picked up a Yamaha VSS-200 at a flea market, it is an 1988 era sampler. 

It caught my eye because of the sampling and it has some voice controls that
looked interesting including ADSR envelope controls and some other stuff. I
have the owner's manual but could not turn up a service manual or schematic
for it. 

I was thinking about adding MIDI to it but without a schematic I am not sure
if I could do more than just play the keys, it looks like some of the signal
path might be analog, but I did not open the case up. It may be pure
digital. 

In any case I would like to find a copy of the schematic and then decide if
I want to get side tracked with yet another project...

Thanks,
Jerry
