Envelope

Four controls for plucks, pads, and everything between.

Not built for macOS, Windows or Linux

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

About

The amplitude ADSR. Attack, decay, sustain, release - the shape of a note over time, and the stage that turns the same oscillator into a bass, a stab or a wash.

Parity

No lane recorded an artifact; there is no parity evidence.

Presets

Start from a named sound, then adjust the instrument to make it yours.

Experimental

Migration fallback: approximated from parameter groups, not a runtime wiring diagram.

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.
