- Bitcrusher (std.crush): Reduces bit depth and sample rate: 2^bits levels, sample-and-hold with jitter, optional triangular dither.
- Chorus (std.chorus): Prepared multi-voice chorus, ensemble and vibrato over arbitrary channel bundles.
- Convolver (std.convolver): Convolution with an attached WAV impulse response: real rooms, speaker cabinets and creative textures, with predelay, trims and gain.
- Delay (std.delay): Tempo-aware, smoothly retimed echoes with colored, ducked and explicit multichannel feedback.
- Drive (std.drive): Four nonlinear shapers with DC removal, tone and latency-aligned filtered oversampling.
- Granulator (std.granulator): Replays windowed grains of the live input: up to 32 at once, scheduled from the node path, with freeze, reverse and pitch.
- Harmonizer (std.harmonizer): Adds up to three pitch-shifted voices to the input, each with its own interval, level and pan.
- Neural amp (std.nam): Play a bounded NAM A1/A2 WaveNet capture with shared DSP, verified model assets and explicit dry fallback when a model is missing.
- Phaser (std.phaser): Swept allpass notches: 2 to 12 stages, a free or transport-locked sweep, signed feedback and channel spread.
- Pitch correction (std.autotune): Detects the pitch of a monophonic input and pulls it to the nearest note of the Toy tuning, a scale or held MIDI notes.
- Pitch shifter (std.pitch): Shifts audio up or down by up to two octaves with a splicing delay line, with fine cents, feedback and a dry/wet mix.
- Reverb (std.reverb): An eight-line modulated feedback-delay network with room, hall and plate-like tunings.
- Vocoder (std.vocoder): Channel vocoder: a modulator on Key imposes its band envelopes on the carrier through 8 to 32 band-pass filters, with formant shift and sibilance.
