plyphon

SuperCollider's scsynth engine, rebuilt in pure Rust - the same engine and API on native and wasm32-unknown-unknown. Each example below runs the engine live in your browser; open it and click the page to start audio.

Synthesis

• sine - the simplest example: a continuous 440 Hz sine.
• motif - a looping motif of self-freeing notes.
• waveforms - cycles through the oscillators through a filter.
• operators - a ring-modulated, soft-clipped bell tone built from BinaryOpUGen/UnaryOpUGen math operators.
• filters - a classic resonant low-pass sweep: a saw through an LFO-swept RLPF.
• moog - a resonant acid bassline: a saw through a MoogFF ladder filter with an LFO-swept cutoff and high feedback resonance.
• noise - metallic rain: Dust2 impulses ring a Ringz resonator over a PinkNoise bed.
• wandering - a generative burble: LFNoise1 wanders the pitch, LFNoise2 sweeps the filter, LFDNoise3 shimmers the amplitude.
• auto-wah - an envelope-following auto-wah: a PeakFollower tracks a plucked source's amplitude and drives an RLPF cutoff.
• scale-walk - a scale-quantised melodic walk: an LFNoise1 indexes a scale buffer through Index, always landing on in-scale notes.
• bell - modal bell synthesis: an Impulse strikes a Klank bank of inharmonic resonators, ringing a struck-metal bell.
• wavetable - a morphing wavetable drone: a VOsc sweeps through a bank of increasingly-bright wavetables, crossfading sine to saw.
• vowel - a synthesized sung vowel: three Formant oscillators voice the formants of an "ah" over a vibrato'd fundamental.
• granular - a granular time-stretch: Warp1 smears a short synthesized arpeggio into a slowly-morphing stereo pad, holding pitch while a slow pointer stretches time.
• reverb - a cavernous space: two Karplus-Strong plucked strings on drifting clocks smear through a large GVerb feedback-delay-network reverb.
• sample-hold - a self-playing sequence: an Impulse clock latches a pitch contour with Latch into a plucked saw.
• waveshaping - a wavefolder: a sine driven hard through Fold with an LFO-swept drive.
• chaos - a chaotic drone: a CuspN oscillator through a filter swept by a slow LatoocarfianN map.
• hard-sync - a hard-sync lead: a SyncSaw whose saw frequency is swept by an LFO over a fixed pitch.
• bouncing-ball - physical-model percussion: a TBall bouncing on an oscillating floor rings a Ringz resonator.
• envelope - percussive plucks shaped by multi-segment EnvGen envelopes.
• pan - a tone auto-panned across the stereo field with Pan2.
• feedback - feedback FM: voices modulate themselves through a one-block-delayed LocalIn/LocalOut bus.
• delay - a feedback echo: a plucked ping recirculated through a DelayN delay line sized from its maxdelaytime.
• comb-string - Karplus-Strong plucked strings: noise bursts excite a tuned CombL resonator, diffused by an AllpassC.
• custom-unit - a custom unit generator (a tanh saturator) registered alongside the base set.
• duty-seq - a self-driving melodic sequencer: Duty.kr pulls pitch and rhythm from demand-rate Dseq/Dseries/Dwhite sources on the audio thread.
• drunk-melody - a self-driving drunk-walk melody: Duty.kr clocks a Dibrown random walk over MIDI notes, glided by Lag.

Buses & control

• routing - an LFO-swept filter on noise, wired through audio and control buses.
• control - host-driven control buses: an arpeggio steered by /n_map + /c_set.
• node-control - in-graph node-to-node control: separate gater nodes pause, resume, and free the drones by id with Pause/Free.
• glide - the control family: a portamento lead glides between notes via a LagControl while a TrigControl ticks each onset.

OSC & scheduling

• osc - drives the engine through encoded OSC packets; the command log prints to the console.
• schedule - sample-accurate rhythm: time-tagged OSC bundles scheduled ahead of the audio clock.
• triggers - a SendTrig clock fires /tr beats the host turns into notes; voice groups self-free via a done action.
• send-reply - audio→host emission: an amplitude follower reports its level via SendReply (/amp), logged to the console.

Buffers & files

• scgf - loads a SuperCollider SCgf-compiled SynthDef and plays it.
• sampler - loads a WAV through a BufferSource (fetched on the web) and loops it with PlayBuf.
• stream - streams a WAV from storage in chunks and plays it with DiskIn.
• record - captures a pitch sweep into a buffer with RecordBuf, then loops it back with PlayBuf.
