  That's right folks!
  I'm <<finally>> going ahead with the production of faceplates for the
  ASM-1 project!
  (thanks to Stew and others who filled me in on Metalphoto).

  The first run will be for 50 (yes, 50!) panels.
  Gene has given his blessing on the layout and will be ordering 10 of them
  - I'll be keeping 4 for myself, so that leaves plenty for all you
  builders out there.


  The specifics;
  Price per panel:    $20-25 (I don't know what shipping costs will be yet)
  Time:               About 4 weeks
  Size:               4 rackspace (7"x19")
  Thickness:          1/8" total - .020Metalphoto laminated to .090plate.
  Holes:              Rackmounting ovals only.

  I've done a lot of research during the past week to get the best price.
  Prices varied tremendously from one vendor to another - I got quotes as
  high as $60/panel and everything in between. I checked with everyplace I
  could find on the net as well as a couple of places I found in the Thomas
  Register - so you can trust that this is the best price around...

  Note that you will not have to do the laminating, it will come that way.
  You'll be getting a complete 1/8" panel. I have been assured that this
  lamination is just as good (if not better) than solid 1/8" plate. Just as
  permanent and better because it's;
  a. Cheaper
  b. Laterally stiffer

  You must drill the holes yourself for the jacks and knobs. There are
  cross hairs where each hole should go. The cross hairs are small enough
  that they will not show if you use 1/8 jacks.

  Panel layout is available via email as a .gif or zipped .bmp file. If
  someone would like to put it on their web page, I'd appriciate it because
  I do email through Lotus notes and sometime attachments don't come
  through for other people.

  I will be sending my order in (a check and the disk with the layout)
  first thing Monday morning.

  I am now taking orders, so reserve your panels quick! I don't need checks
  now - just reservations. I will ask for checks when Metalphoto says
  they're ready to ship the panels - that way I can send your orders out as
  soon as the panels arrive...

  The panel specifics are as follows;

  All knobs are at least 1.4" center to center.
  At least .75" boarder between the sides and the first knob / jack
  At least .25" board between the top/bottom and the first knob/jack
  Jack spacing is far enough apart to support 1/4" jacks
  Dial markings and style are my own design, kinda modelled after the Serge
  stuff

  Controls included are;

  VCO (2):
  Course Tune Pot
  Fine Tune Pot
  FM Amount Pot
  PWM Amount Pot
  Initial Pulse Width Pot
  (2) 1v/Oct Jacks
  FM Input Jack (scaled)
  Sync Input Jack
  PWM Input Jack (scaled)
  Saw Output Jack
  Pulse Output

  VCF (1):
  Frequency  Pot
  Scaled CV Pot
  Resonance Pot
  Input volume for input 1 Pot
  Output HP/LP mix Pot
  HP/LP or BP Switch
  (2) 1v/Oct Jacks
  Freq CV Input Jack (scaled)
  Audio Input Jack (scaled)
  (2) Audio Input Jacks (no scaling)
  Audio output jack
  VCF Note 1: The output of the VCF as set up in the panel offers a little
  more flexibility than the original four output VCF. You have a switch
  that when in one position sends the BP output to the output jack, when in
  the other position, it selects the output of a linear x-fade between the
  LP and HP outputs. The amount of x-fade is controlled by the pot. Notch
  output occurs whenever the pot is not panned hard left or right and will
  be or less to the HP or LP side depending on it's positon. This requires
  a <<slight>> modification to the circuit, but does not require any extra
  parts (actually it requires LESS parts).

  VCF Note 2: The scaled CV input is drawn as an "inverting scale" - this
  means that when centered, the cv has no effect. As you turn the scale to
  the left, a positive CV cause will cause the frequency to drop. Turn the
  knob to the right and a positive CV will cause the frequency to go up. It
  may be possible to do this with no extra parts - Gene and I are going to
  look into this. Otherwise, it can definitely be done with the addition of
  a single op-amp that can be glued to the back of the panel. We will send
  complete instructions. If you don't feel up to it, you could always just
  wire this as a regular scaled input and ignore the face plate marking,
  until you feel like "enhancing" it.


  ADSR (2):
  Attack Pot
  Decay Pot
  Sustain Pot
  Release Pot
  Gate In Jack
  ADSR Out Jack

  VCA:
  Initial Gain Pot
  Output Level Pot
  (2) Gain CV Jacks
  Normal Input Jack
  Inverting Input Jack
  Output jack
  Note: there's room for two output jacks so you can put both a banana jack
  and a 1/4" (as your final output).

  Scale:
  Scale Amount Pot
  Input Jack
  Output Jack

  Noise:
  White Output Jack
  Pink Output Jack
  Low Freq Output Jack

  LFO:
  Rate Pot
  Tri. Output Jack
  Square Output Jack

  Glide:
  Glide Rate Pot
  Input Jack
  Output Jack
