i would suggest using something like [hsv2rgb] and feeding the 
note-value (scaled to 0..1 and probably pre-processed with a [% 12] to 
the color-angle (hue))
and you could map velocity to (e.g.) value (luminance)

this way you can also colorize microtones and/or change the scale and/or ...

very minor: while 4 files is not that much to download, it would be very 
nice to have a bundle (tgz/zip) where you can get all files with 1 click.

minor: why are you using pdradio? of course you are free to do so, but 
once we find the time, we will hopefully migrate it to puredata.info; 
the more user-data there is at that time, the more complicated it will get.
so please everyone, use puredata.info instead of pdradio.iem.at for 
sharing anything but streamed music.

i think what you are looking for is voice allocation, which can be done 
by [poly] (infamous but core pd since ever)
