Done! Results are attached, with GEM example help patch. Could also be useful for controlling PWM dimmer for RGB lights or LEDs.
best! D.

I also found this:

Which seems much more useful for the task at hand. But not being much pf a C programmer, it could take me some time converting it into a Pd patch. I'll report back...

Hey gang,
before I go reinventing somebody else's wheel... has anybody written something that takes a (sound) frequency in Hz or MIDI note and outputs the transposed color in RGB values? Along these lines:
F#44 = 737 nm(Infrared) G 44 = 696 nm(Red) G#44 = 657 nm(Red) A 44 = 620 nm(Red-Orange) A#44 = 585 nm(Yellow) B 44 = 552 nm(Green) C 45 = 521 nm(Green) C#45 = 492 nm(Green-Blue) D 45 = 464 nm(Blue) D#45 = 438 nm(Violet) E 45 = 414 nm(Violet) F 45 = 390 nm(Ultraviolet)
Or even something that takes the light wavelength in nanometers and gives separate RGB values? I'm working on a simple color organ for a friend this week.

Have fun..
