This is an entry to the Korg Monomania Sound contest, in which it was a runner-up. It consists of four drum kit sounds made on a monotron: kick drum, snare, cymbal crash, and cowbell. The sounds were made using a monotron with white noise or a dummy plug. (A dummy plug is an input cable plugged into aux with no signal applied. This holds the filter open without triggering the oscillator.)
The video shows the settings needed to create the sounds, depicted on my monotron patch sheet.
A zip file with the sounds and patch images is available here: monotron-drum-kit.zip.
