First patch with SSF PTG (Positronic Transient Gate)

Published on Mar 13, 2013 radiokoala·20 videos

"Steady State Fate PTG is a multi-function dual vactrol-based module that can generate envelopes (among many other things). In this video you could see it in action both for FM and AM purposes.

Patch description :::

pitch of a Sputnik DWG VCO is modulated by PTG channel two (multed both to 1v/oct and linear FM inputs) and another envelope controls PTG's internal VCA on channel one.

PTG volume envelope is triggered by a monotribe 5v out. (At steady tempo.) Then volume envelope's step response is modulated by the same envelope as a pitch but inverted (-env out), and the pitch modulation envelope's step response is modulated by a VCO it itself modulates. Therefore channel B modulates three destinations, and channel A -- amplitude only."
