Detailed Description¶

Author:

Ben Sergentanis

Date:

Jan 2021 Uses a few magic numbers taken from the 909 schematics:

Ratio between the two modes of the drum set to 1.47.
Funky coupling between the two modes.
Noise coloration filters and envelope shapes for the snare.

Ported from pichenettes/eurorack/plaits/dsp/drums/synthetic_snare_drum.h to an independent module. Original code written by Emilie Gillet in 2016.
