CLAP Plugin Forge

Build Real Audio Plugins with AI – Not Broken Prototypes

You asked an AI to build you a synthesizer. It gave you code that aliases above 5kHz, spikes to 100% CPU from denormals, clicks every time you turn a knob, and crashes your DAW because it allocates memory on the audio thread.

CLAP Plugin Forge fixes this. Every prompt encodes the hard-won constraints that separate a working prototype from a shippable plugin: real-time safety, band-limited oscillators, parameter smoothing, denormal protection, and proper host integration.

All prompts target nih-plug (Rust) and produce both CLAP and VST3 plugins.

What’s Inside

MIDI Plugins (8 prompts)

Build tools that process and generate MIDI with sample-accurate timing:

Arpeggiator – 6 pattern modes, host tempo sync, swing, velocity curves, latch
Chord Generator – 12 chord types, inversions, strum timing, humanization
Euclidean Sequencer – 4 tracks, Bjorklund’s algorithm, probability, accents
Note Repeater – Tempo-synced stutter, velocity ramp, pitch shifting
Scale Quantizer – 15 scales, quantization modes, microtuning
Velocity Processor – 5 curve types, humanization, range mapping
CC Mapper – 4 routing slots, curve shaping, smoothing
Generative Melody – Markov-style interval control, scale-constrained

Audio Effects (13 prompts)

From bread-and-butter tools to creative processors:

Filters: State-Variable Filter, Moog Ladder (4-pole with self-oscillation), Comb Filter, Formant Filter (vowel morphing)

Dynamics: Compressor (RMS/peak, sidechain, lookahead), Transient Shaper, Noise Gate

Time-Based: Stereo Delay (tempo sync, ping-pong, filtered feedback), Chorus, Algorithmic Reverb (8-channel FDN)

Saturation: Tape Saturation (hysteresis modeling), Bitcrusher (TPDF dither), Wavefolder (ADAA anti-aliasing)

Synthesizer Engines (5 prompts)

Complete polyphonic synth architectures with voice management:

Subtractive / Virtual Analog – PolyBLEP oscillators, multi-mode SVF, dual ADSR, polyphony, unison
Additive – 32-64 partials, spectral morphing, harmonic/inharmonic ratios
Wavetable – FFT-based mip-map generation, cubic interpolation, 4 wavetable sets
FM – 6 operators, 8 DX7-style algorithms, per-operator envelopes and feedback
Granular – 64-grain pool, configurable windowing, spray/scatter, freeze mode

UI Design (6 prompts)

Build interfaces that look as good as they sound (nih-plug-egui):

Custom rotary knobs with modulation rings
Real-time spectrum analyzer
Oscilloscope and wavetable 3D visualization
Modulation matrix routing UI
Full plugin window layout with preset browser
Dark/light theming with neumorphic elements
