ASM-1 Faceplates for sale

[Mathias Tornqvist]

ALthough I, like Jupiter4, haven't had the cash to buy one of Gene's
boards, I have very firm plans to do so whenever I get the chance (so go
ahead and make another batch, Gene!) My plans for the layout are very
similar to Christopher Lists, but a few small changes on his design would
make it perfect (for me...)

>** VCOs (2)
>Jacks:
>2 * 1v/oct
>Synch In
>FM in
>PWM In
>
>Knobs:
>Course Tune
>Fine Tune
>FM amount
>PWM Amount

How about sacrificing the sync input on one VCO and have a linear FM input
instead (is linear FM availible in the ASM-1?)

>** VCF
>Jacks:
>3 * 1v/oct
>2 * Audio In
>Audio Out
>
>Knobs:
>Frequency (I never use fine tune for filters)
>Q
>LowPass / Highpass x-fade
>
>Switch:
>Bandpass or Lowpass/Highpass

I'm not sure what I'd use 3 1v/oct inputs for on a filter. It seems more
flexible to have 2 inputs, and an Amount knob for one of them. If the
Bandpass is integrated with the X-fade pot (SEM style), you'd have room for
a Balance knob between the two audio inputs.

...

>** VCAs(2)
>Jacks:

>Knobs:
>Initial level

How about a Modulation Amount knob? then you can adjust AM amount frmo
VCO's, direct-patch the LFO without getting a mega-tremolo. Envelope to VCA
could be adjusted for level control (Odyssey-style)

Other than these, the layout is similar to what I had in mind. I'd use
banana jacks, since there aren't any mults planned.

Question: Would it be possible to stack banana plugs to inputs of the synth
witout getting inpedance/level matching problems? For example, run two
VCO's into a VCA input without any mixing circuitry?

I also had another thought... A matrix patchable version (EMS-style) would
be compact, tidy and cute. But since pin-matrixes are hard to get to these
days, how about a grid of dip switches? For example 16 12-position dips
stacked vertically, the 12 position representing outputs, and the 16 rows
repesenting inputs. Are there 16-poition dip switches? 12 outputs may be a
bit restricted. Perhaps 8+8x16...

Would this be too flimsy, fragile and generally unbearable? It wouldn't be
too expensive (16x$2 for 12 position switches), and pretty compact
(6.5"x1.3") Any thoughts? Alternatives?
