ColorMusic Mirror

ColorMusic is a cool application for Mac OS 9 that lets you “play” an image my moving your cursor across it, converting the colors at each point into the pitch, velocity and duration of MIDI notes.  The site that used to host it is no longer in service, but as it has a license that allows for free distribution, I have created a mirror download for the program here.

Note that as this is an OS9 application, you will need to set up an emulator environment such as SheepShaver to be able to run it.

ColorMusic AppOnly (uncompressed .tar containing app file only)

The text from the readme is included below.  Please note that the contact and download information that it includes no longer works, so to get the application you will need to use the direct link on this page.   I do not have a copy of the source code, so the download contains only the application and the readme.
