Hi,
we did something similar for illustrating microtuned scales with JOGL and a SK-88Pro. The paper describing it is at:
http://www.ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/4385040/4385041/04...
and the prototype at:
http://julovi.net/j/?page_id=355
best wishes,
Julian Villegas

are you using this version:
http://grrrr.org/ext/beta/macos/pd/
the difference between py and pyext:/
py/ loads Python modules and execute the functions therein;/
pyext/ uses Python classes to represent full-featured message objects.
sorry i'm not using mac os x, so i cannot test.

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.
Danke + best!
D.

I also found this:
http://www.mail-archive.com/use-revolution@lists.runrev.com/msg17390.html
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...

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