ASM-1 Faceplates - Part II

[Christopher_List at Sonymusic.Com]

Howdy DIYers -

Well I got a pretty good response to the question "would anyone be
interested in a sub-module faceplate for the ASM-1" - so I decided to
investigate further. The good news is that I decided to; make it 3
rack-space instead of two, put more stuff on it, spread the stuff out a
little more, and get a price quote. The bad news is the price. For a 10
piece order (That's what I was assuming based on the initial response) the
price would be about $40 - $45 each : shipping included. This is MY COST -
I will not make any money on this (I didn't really make anything on the
other ones either). The higher cost is based solely on the lower quantity.

I would still be willing to have them made provided I can sell at least 8
of them.

Now here's the other thing - I have schems for the circuits (and I've built
them all and know they work) but I don't have PCB layouts. A couple of
people have offered to put in some time doing PCB layouts, and I do have
layouts in Visio that I used for protoboarding the circuits that I should
be able to make into one sided PCB layouts w/o too much trouble. I can't
offer anything in return for anyone's time spent on the PCB layouts - if
you actually got the boards made, you could sell 'em.... Right now,
however, all I can absolutely provide is the schems, the rest is up to
you....

I (of course) have a .gif of the layout available, and it'd be nice if
someone could WWW post it because a lot of people have trouble with
attachments and uu-encoding and stuff. I may  it before I'm done, but the
one I have now looks really sharp.

It includes panel makings for the following;

External Input Follower: This is a voltage follower / audio input buffer
with gain and gate level knobs, audio, gate, trigger, and envelope outputs.

Extra ASM-1 VCO outputs: Outputs for a sine and triangle wave converter for
the ASM-1 VCOs - perfectly lined up with the existing faceplate VCO outputs
:). I also left room for extra stuff here - incase you want some other
weird output.

CV Mixer: Three inverting/scaling inputs, one output. The third input has a
switch that automatically runs +15v to the third input allowing it to be
used as an offset voltage.

EN/Barry Klein Timber Modulator #1: This is the "voltage controlled
distortion" circuit from Electronotes and the Barry Klien book. 3 knobs,
two inputs, one output, one switch.

Ring Modulator: X in, Y in, X*Y out - pretty straight forward.

Sample and hold: Jacks for Input, S&H Output, Triggered Sample input (turns
any input into a short trigger), and Track and hold tracking input causes
the output to track the input as long as this input is "high)

CVable AD / AR / Slew Lim: Based on my own design - I've found this to be a
very useful circuit. Works as either AD or AR depending on which input is
used, <OR> AR / Slew Lim based on how a switch is set. It also works as an
LFO is you run the "end pulse" output back to the trigger input, and the
faceplate includes a marking for a switch that would do this automatically.

2 Channel CV-able mixer: Each channel can work in CV-pan or CV-fader mode.
Provides aux. inputs so that multiple mixers can be chained together, and
has other neat features that I won't bore you with now....

So the question is; who (if any) want's one or more of these at this price?
If I get requests for 25 it'd probably be cheaper...
