Yamaha SK20

    Hi, this is my first post to this group....I posted this to
alt.music.synth, but this group seems a little more active so I thought I'd
try here too....

    I just bought a yamaha SK20, and I must say I love this thing! I am
curious if anyone has a service manual or schematic for this thing (nothing
is wrong with mine...yet..) and/or if they know a way to detune the saw
'string' section relative to the polysynth section? The polysynth detune
knob seems to affect both, and since they sound pretty sync'd to each other
I'm pretty much betting that I can't, but it would sound so much nicer if I
could!

    Thanks!
