Here is a Simple First order Markov sound maker
AUX Switches between Sawtoocm & Pulse
Aux3 Invert Comb Filter
Aux4 Stops/Starts MArkov Sequence
Relatively Simple Instrument so i added a comb filter to turn it into a Markov Drone Maker
The orginal code had this weird setup that muted everything on initialization so tweak some values wiggle some knobs then unMute on Aux3 and you Will Get Sound.
