Detailed Description

Naive snare drum model (two modulated oscillators + filtered noise).

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.
