MOTM

What I've decided is the PWM version, with 1 out. Ther is no VC blend (I
never said that!). Remember,
the intent is make a smaller, CHEAPER, VCO.

You will be able to use the '130 VCA for 2 signal blending (fade) and 1
signal splitting (pan).

Now I have to see if the circuitry will fit on a '800 pcb. It's a tight
squeeze, but I'll do a parts placement
over the weekend.

As you have noticed, there is a flurry of R&D now since NAMM is looming on
the horizon.

I'm no EE, but aren't pots one of the most expensive parts??  How about a
310 with no VC blend, but with...

3 knobs:

COARSE
FINE
FM (attenuator)

and

5 jacks:

1V/OCT
FM
PWM
SAW
PULSE

Would that work??  This way saw and pulse will both be available at the
same time -- a feature found on every VCO I have ever seen.

You also sell a mixer, which could do the non-VC blending.

However, you cannot do any sort of blending, VC or otherwise, unless the
310 has at least two outputs to blend!!

So an additional output is much more useful than a blend knob.

Couldn't a regular sized PCB be mounted on the back of a 1U module??  Also
couldn't you order PCB's in any size you wanted??

Excellent :)

---- GK ----
Mark makes good points.  Having both saw and pulse outs would be preferable
to a manual blend knob, since one can manually blend using an 830, and a
cost savings would be beneficial.  I'm wondering if a 5th jack would
interfere with the PCB?  (When I look at the 800, it looks like it would
fit.)
