Well, I got it all fixed up pretty much.  Still a few flaky
connections it appears.  THe organ didn't work til I tapped on it
tonight :).  But it's almost perfect.

These are a rare machine. Maybe 500 built?  I see there were a couple
serial series U1 and U2 and I've seen only up to 200 something in one
and mine is 166 in the other.  Anyway these sound GREAT! There is a
mixer for the 4 sections and bender for monosynth only and mod for all
other sections' vibrato.  (with speed knob right there by the wheel) I
don't know what the 'touch dynamics' knob does.  There is no velocity
on this thing.  Two busses on the keyboard but one is for monosynth
and one for the others.  Not for calculating velocity.  ANd no AT
strip sensor or anything so..I dunno yet on that. Schematic anyone? 
Also it has a breath input (tubing goes directly in) which can be
switched to give volume control for either poly or mono synth section.

Anyway, the review of sounds/features per section:

1) Performer sounding strings pretty much save the cool eq of the
performer of course.  But at least the same kind of quality for the
tones it does have and a decent eq sweep and 8' 16' 'stops'.

2) 4 great preset organ tones plus percussion stops with master volume
and decay knobs.  Overall organ 'sustain', a release envelope.  It's
all paraphonic with retrig on all notes off but wow.  Great BBD leslie
emulator that speeds up and slows down like the real thing.  And nice
tone selection.

3) Polysynth is at least as nice as the ARP omni's I think overall.  I
dunno that ARP filter is awful cool sounding I think.  But the curtis
CEM3320 is ok too in it's own way and there is one of them shared
again with eg retrigger when all notes are lifted.  CEM3310EG, and
CEM3330vca.  These same three chips are in the mono section also.  But
on the poly section there are three presets...a nice piano enveloped
sound and a more brassy sound and a more tweaky synth sound... and
then you can select 'free' which means you program it with the knobs
for ADSR, amount (invertable like Korg Delta etc.) and
cutoff/resonance.  Anyway in the oscillator control section there are
two oscillators and both can be dropped an octave with a switch and
one can be detuned up or down a fifth or like that.  Also second
oscillator can be muted.  You can select between square and saw for
both independently.

4) Monosynth is one oscillator.  But you have more waveform
types..pulses and triangle added and also you can vary footage from
32' to 4' I think it is.  PORTAMENTO amount is very useful for
creating sounds where the lead lage the other parts.  This thing can
sound very phat for a divide down based unit!  

This is a tremendously undersaught unit it seems to me.  They were
rare and at the end of an era..the year before MIDI.  And the DX7. 
Wish list?  Oh...independent lfo for the monosynth?  But I'm really
looking forward to recording with this thing! -Bob
