ASM-1 Faceplates for sale

     A couple quick points...
     
     Yes the ASM-1 does have linear FM inputs on the VCO's.
     
     My inclination is to always have at least one variable attenuation 
     input per summing node on every module. The ASM has some pretty wide 
     sweep ranges so mod depth pots would be highly recommended.
     
     You may be able to get by with only a course tune control on the VCO's 
     if you use a multi-turn pot, but these things are quite expensive and 
     should be tried before committing them to a panel.
     
     As for banana plug stacking on inputs - be sure that all outputs have 
     1K resistors (i.e. add them to the outputs that come straight off of 
     the op-amps). Then you can stack away, input or output. However be 
     aware that stacking two outputs together means that you will have two 
     signals fighting each other at 1K impedances, on a 100K input, so that 
     the actual composite signal will be averaged rather than summed. 
     Therefore two five volt waveforms will peak at five volts when mixed 
     as an average, but will peak at ten volts when mixed as a sum (2 
     seperate inputs).

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?
