With this "flow chart" style of patch diagramming in my head, I looked over at my ARP and thought, "what if they had adopted those symbols and used them on the panel instead of merely using rectangles for all modules?" So while I think about making some graphics for diy modules which might incorporate this notation, I wanted to ask specific questions about the system since I don't remember it that well:
1) Oscillators (and other signal sources) are round -- I can see this is a great indicator since the sources are cyclical, and the radians, and the thing.
2) VCFs, VCAs and mixers are right pointing triangles -- I can see this is a good indicator since these look kinda like an op amp figure pointing in the direction of signal flow.
3) CV sources (ADSRs, keyboards, sequencers, S/H) are rectangles -- I can see this because they wouldn't be round or triangular<g>.
Now I believe that ring modulators, timbre modulators, reverbs, FFBs, the Wave Warper, the Time Machine, the Mini Wave, Wave Multipliers would all be modifiers/processors and hence be written as a triangle. Is that true?
I believe that S/H are documented as rectangles, but aren't they really modifiers too? And how are lag processors documented? Aren't they just filters and shouldn't they be documented the same way with triangles?
What about pulse and frequency dividers? What about VC switches (like the great MOTM 700)?
Just wondering if these have been worked out,

That was always my favorite method of documenting patches.
And I got about four of my patches published in Polyphony way back
then! I think I made $5.00 per accepted patch, which may very well
be the first professional music gig I ever had! :)
