7. Effects - Nebula Sound System documentation

The 33 built-in effects, the device chain, presets, sidechain keys, the master chain, note effects and analysers.

The device chain on a track, and the master chain

Add an effect: the track's fx button (or the browser's Effects list) — pick from 33 built-in effects, each with factory presets: delay, ping-pong delay, comb, stutter, Haas, reverb, convolution reverb, EQ, auto-filter, tremolo, auto-pan, vibrato, compressor, multi-band compressor, gate, expander, transient shaper, de-esser, limiter, look-ahead limiter, utility, distortion, saturator, wavefolder, bitcrusher, chorus, flanger, phaser, ring mod, octave, pitch shifter, vocoder, granular.
Reorder by dragging; bypass with the switch on the card.
Presets per effect: save and load (.nebpreset).
Key (sidechain): on any effect that can take a key — a compressor, say — the card has a Key row: choose another track and the effect listens to that track. Ducking a bass with the kick is: put a compressor on the bass, set its Key to the drum track. This works on tracks, groups, returns and the master.
The master chain is the same idea on the master strip; the Mastering card shows it and ends with a limiter — the last safety stage before the file leaves the app.
Note effects: a per-track chain of MIDI note effects (arpeggiate, transpose, scale-lock and friends) with its own card — the notes are transformed on the way to the instrument, and the edit is undoable like everything else.
