Pure Data Clamping VCA with [clip~] (TR-808-style Envelope in Pd Vanilla) | Simon Hutchinson

Описание: Creating an ambient music machine in Pure Data Vanilla with a "clamping VCA" that adds subtle distortion, imitating the envelopes in Roland TR-808.

I made a clamping VCA in Reaktor a few weeks back (   • Clamping VCA in Reaktor 6 Primary with "Mo...  ), and now here's another example in Pd. Normally, amplitude envelopes in synths are a control envelope on the amplitude of the signal. When we use a "clamping VCA", though, instead of controlling the amplitude of the waveform, we clip it at the desired maximum envelope. This means, when the VCA is all the way up, it sounds the same, but during the attack and release, we'll get the addition of subtle (or perhaps not-so-subtle) distortion to our waveform.

I use [clip~] in Pd to achieve this effect, stealing the idea from Noise Engineering's "Sinclastic Empulatrix" module, which, in turn, stole the idea from from the Roland TR-808 drum machine's cymbal envelopes.
