MetaSynth

Version CTX 1.4 has been released adding Universal 2 native code no matter which processor you are running.

"MIDI only has note on and note off. Envelope information is carried separately with the instruments and controllers. In the Image Synth the luminance codes the envelope during the duration of the note which allows for very subtle musical control. The RGB color also controls stereo placement for each note, so you can have a note starting left and moving right while fading out which would be very hard to do in MIDI unless you code that behavior in the synth, but then every note would behave like that. I like to view the Image Synth as a very complete notation system which includes envelope and pan control in the same representation." – Eric Wenger.
