OSC-1
A complete synth built from separate modules.
AvailableEffect
Envelope
Four controls for plucks, pads, and everything between.
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.
Presets
Start from a named sound, then adjust the instrument to make it yours.

Signal graph.
ExperimentalA sketch of the signal path, in the order of the parameter groups.
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.
Goes well with.
Filter
A resonant low-pass filter for shaping tone.
Oscillator
Two oscillators with independent pitch, level, and stereo position.
