MOTM

>a) 3 pots, 6 jacks:

(jacks cost less than pots, LED's draw current and make noise)

1) UP
2) DOWN
3) HOLD

6 jacks:

1) UP
2) DOWN
3) HOLD
4) THRESH
5) OUT
6) SLEW

The time set by HOLD begins when the rising voltage reaches 5V or when the
falling voltage reaches 0V.  THRESH uses a switched jack.  With a jack
inserted into THRESH, and HOLD set to 0, the falling voltage begins when
the rising voltage reaches the TRESH voltage, the rising voltage begins
when falling voltage reaches 5V _minus_ the THRESH input voltage.  Got
that??  Since the falling voltage cannot reach 5V, if THRESH input is 0V
the cycle is not retriggered.  So if the input is a short trigger, it
cycles once then stops.  If the input is a gate, the falling voltage (or
hold) begins when the gate is released.  Note that HOLD also delays the
onset of an envelope.  Modulating THRESH with a voltage can produce various
functions, including a stepped function similar to S&H.

SLEW output is an output -- OUT run through a simple "degenerative emitter"
(but without the trimmers or current source).  It's more like a lag circuit
than true sine shaper to save space and money, but it will produce an
approximated sine if OUT is a triangle.

Features:
Makes tri, up saw, down saw, pulse, trapezoid, various functions, complex
LFO's, and a multitude of unique shapes.
No tempcos needed.
Cannot be replaced by a 320, 300, or 310.
Annoys people who already bought $erge and EM$ synths :)
Can also be used a VC EG.

Disadvantages:
"single sided" output.
No LED to indicate rate -- you'll have to use your ears, tough guy.
No simple "rate" control for tri waveforms (you need a mult).
No simple "PWM" for pulse waveforms (you need to modulate HOLD).
