EMS Polysynthi

[jupiter4]

Hi All,

Well it looks like I've got a new project!

I've just got hold of a Polysynthi serial no 27.

I have spoken to Graham Hinton who designed it and he has been very helpful. I
am also getting the diags from EMS (although they will not support it at all
and I don't blame them).

It has 3 CV ins at the back for pitch, filter, amplitude. filter and amplitude
are full range 0 to 10 Volts. But the pitch one only does about a semitone or
three either way. BECAUSE the mod buss goes to the 4046 master oscillator and
the keyboard drives the octave dividers directly, the variance to the VCO in
the 4046 is quite small which is why the mod amount to VCO is so poor.
I'll have a bit more info on it when I get the diags...

TTFN and merry soldering  christmas,

Dave...
