Envelope

Four controls for plucks, pads, and everything between.

@maru shared this effect so you can play it in your DAW, remix it or put it on your site.

A stage of OSC-1. It works the same on its own page as it does in the chain, same parameters, same paths.

What it does

Envelope shapes the volume of an audio signal with MIDI notes. Play a note and the sound fades in, settles and holds; let go and it fades out. It turns a drone, a pad or any continuous sound into something you can play from a keyboard.

The 14 HP rack panel exposes audio input, MIDI gate input and audio output. It shapes the audio passing through it; it does not emit a separate CV envelope.

Good to know

Envelope is mono and responds to every note the same way. Any new note starts the envelope again from the top, and any note-off releases it, whatever the pitch or velocity. It shapes the audio you send it and makes no sound by itself, so connect an audio source first. Hear it plays a held middle C through it so you can check a setting without a keyboard.

Guide and controls

How it works.

A four-stage amplitude envelope applied per voice. Attack and decay run on exponential curves because linear amplitude ramps do not sound linear - the ear hears loudness logarithmically, and a linear fade sounds like it stalls at the end.

Release starts from wherever the envelope has actually reached, not from the sustain level, so releasing during the attack phase fades from that partial level rather than jumping up first.
