Unidentified Commodore Experiment

Randomly found this, not really sure what Krokko had in mind with it, I guess that some kind of 303 inspired application for the C= 64 judging from the filenames and the way he twiggles the knobs with the cutoff and resonance? filter. The line of basic displayed confuses me even more... =)

So, no idea about the software used and the actual goal of this experiment or whatever it is...

Just have a look at these videos and ponder yourself... if you want. =) Any ideas ???

According to getlofi.com "...it looks like a poke to a certain memory spot triggers a pulse and somehow the 2 added potentiometers create an RC filter circuit that uses the COM data lines. Strange yes, cool definitely.."
