			I built a patch, which semi- generates music under the influence of an incoming audio signal. Semi-generative should mean, that it randomly picks on predefined notes, makes changes in the note length, rhythm parts and volumes of the instruments and effects. The notes however are predefined and the “Snare” remains
			the only constant part of it to keep the output harmonic. All Sounds are built from cosine oscillators, with the exception of one saw-tooth oscillator.

			===Notes regarding the Patch===
			The fader section on the top of the patch is a control instance. When starting the patch, the faders have to be reset to zero, otherwise the sounds will start playing at random levels (sometimes distorted) before the fader movements kick in. This is a bug i couldn't fix, therefore the faders. I chose to exclude the overall tempo from randomness, but still it is adjustable.
