Projecttitel: Syinsi Stomper "Bassdrum Module"


Startdate: July 2016

Duedate: August 2016

Manufacture link:

STOMPER is a percussion generator that uses an unfiltered square-wave oscillator. Quickly sweeping the oscillator results in a satisfying high-q-sounding zip and thud thanks to all the crazy harmonics.
