Very bass harmonics for kick (to be played in parallel) and at lower volume for snare and tom bass harmonics. It was created by filtering a 60 hz sine wave (remove all the high frequencies but also the extreme low).
Kick from my first sample session with my fresh eurorack:- envelope generator: make noise maths- oscillator: doepfer a-110-1 vco- filter: doepfer a-124 vcf5 wasp.
