«IDMish modified. It is inspirated from the work of xffff.» by jerome.lapuyade.lahorgue

This patch uses a SynthDef with Demand and triggered Ugens inside. The advantage of this rather using Pbind is the ability to play very speed rhythms without saturating the server. Indeed, only the OSC message to start the synth is sent by Synth; whereas with Pbind, if the tempo is too speed, a lot of OSC messages are sent during a short time interval.
