Wavetable Synth

The flagship polyphonic synthesizer.

16-voice polyphony — with voice stealing
2 oscillators — with wavetable selection and 8 waveforms: Sine, Triangle, Saw, Square, Pulse25, SuperSaw, Organ, Vocal
Sub oscillator — tuned 1 octave below oscillator 1
White noise generator — with level control
Resonant multi-mode filter — : Low-pass, High-pass, Band-pass, Notch (state-variable)
Filter ADSR envelope — with cutoff modulation and key tracking
Amplitude ADSR envelope —
2 LFOs — with 5 shapes: Sine, Triangle, Saw, Square, Random
Unison mode — : 1–8 voices with detune and stereo spread

Analog Synth

Subtractive analog-style synthesizer with deep modulation.

16-voice polyphony —
3 oscillators — with 7 shapes: Saw, Square, Triangle, Sine, Noise, SuperSaw, Pulse
Hard sync — (oscillator 2 synced to oscillator 1)
Ring modulation — (oscillator 1 × oscillator 2)
FM synthesis — between oscillators
Pulse width modulation — with LFO target
Dual multi-mode filters — (serial or parallel): LP12, LP24, HP12, HP24, BP12, BP24, Notch, Comb — each with independent ADSR
3 ADSR envelopes — (amplitude, filter 1, filter 2)
3 LFOs — with tempo sync and key retrigger — targets: pitch, filter cutoff, amplitude, pan, PWM
Voice modes — : Polyphonic, Mono, Legato, Unison
Portamento/glide — with constant time or rate
Analog drift simulation — for pitch and filter instability

Yamaha DX7-style frequency modulation synthesis.

16-voice polyphony —
6 operators — with 32 algorithm selections
8 waveforms per operator — : Sine, Triangle, Saw, Square, Pulse, Noise, FM Feedback, Custom
Per-operator controls — : frequency ratio, fine detune, ADSR envelope, feedback amount, output level, velocity sensitivity
Pitch envelope — and **master SVF filter** with ADSR
Unison — : 1–4 voices

Grain-based synthesis for textures, pads, and sound design.

8-voice polyphony — with up to **2048 total simultaneous grains** across all voices
Grain-based playback from loaded samples (up to 60 seconds at 44.1 kHz)
Grain parameters — : size (5–500 ms), density (1–100 grains/sec), position, scatter
Pitch randomness — per grain
4 window shapes — : Hann, Gaussian, Triangle, Trapezoid
Freeze mode — grains repeat from a fixed position
Reverse mode — grains play backwards
Per-voice ADSR envelope

Sample-based drum instrument for the step sequencer.

16 pads — mapped from MIDI C1 (note 36)
Per-pad controls — : volume, pan, pitch (−24 to +24 semitones), attack, decay, cutoff, resonance
Choke groups — (0–4): triggering one pad silences others in the same group
Output buses — (0–4) per pad for separate processing
Per-pad color coding, mute, and solo
Lock-free sample loading for glitch-free playback

Physical modeling for acoustic instrument simulation.

16-voice polyphony — with voice stealing (lowest energy)
5 model types — : Plucked (Karplus-Strong), Bowed (waveguide), Blown (pipe), Struck (mallet), Percussion
5 exciter types — : Impulse, Noise, Burst, Bow, Breath
Allpass fractional delay — for precise tuning
Body resonance — via dual formant filters
Sympathetic resonance — and inharmonicity parameters
Pickup position, damping, and brightness controls

Transient-aware sample slicing for beat chopping.

Multi-zone sample playback engine.

The Advanced Sampler engine is fully implemented but is not yet listed in the Instrument Browser UI. It can be instantiated via the scripting API.
