[sdiy] X-mas gift...

[Rönnberg Niklas]

Hi!

I got an Yamaha PS-3 this christmas, and I like it. Yes, it's very simple,
but there's something about the sound that I like. Anyway, since it's so
simple I wonder if someone has a schematic, so I can mod it.

As I understand there are about four different squarewaves, with different
pulse widht in the synth, and four analogue filters. Maybe I could insert
some switches and some mixers to make my own sounds... Anyway a schematic
would be very useful.

Best regards, and happy new year!
