I updated the patcher I did last week by experimenting with the sound-text-video conversion. I copied the basic build for the jit.matrix object, that you can find that when right clicking the objeckt and then clicking on help, where you can assign certain planes a value. I made it so that, in the window with each frequenz blicks a different value to the rhythm of the melodie. After saving and reopening the patcher my values didn't save. But you could technically assign your own values and make colors blick to the rhythm.

Here is the Patch: File:Für Elise 2.maxpat
