«Noise bursts and clicks going through ringing filters» by blaz.pavlica

on 27 Mar'26 19:27 in glassdrumsbellsphysical

A bunch noise bursts and clicks going through ringing filters, sequenced with patterns.

marimba and wood SynthDefs are taken from this blog https://thormagnusson.gitbooks.io/scoring/content/PartII/chapter11.html

Needs ChordSymbol quark to work.
