Jaw Harp Synth is the first physics-based jaw harp synthesizer for iPhone. Create authentic khomus and kubyz sounds, build beats with the drum sampler, and bring your music to life with AI-powered pattern generation. AUTHENTIC JAW HARP SYNTHESIS • Physics-based sound engine modeled on real Yakutian kubyz acoustics • Morph between 5 vowels (А, Э, И, О, У) in real time using the XY pad • Three-band formant filter for authentic jaw harp timbre • Velocity-sensitive pluck dynamics — from soft to percussive • Outward and inward articulation styles • 5 cavity resonance modes based on Yakutian playing tradition DRUM SAMPLER & BEAT MAKER • 9 pads (3×3 grid) for finger drumming • Import WAV, CAF, or SFZ samples • Record new samples directly from your microphone • Real-time waveform trimming editor • Velocity-sensitive touch pressure control 16-STEP SEQUENCER • Program beats step by step or record in real time • Adjustable tempo (60–160 BPM) • Loop length control • Sub-10ms latency for tight, responsive playback NEURAL PATTERN GENERATION • AI-powered beat creation using DAG-based pulse propagation • Generate patterns intelligently based on tempo and style • Smooth morphing between pattern variations PROFESSIONAL AUDIO ENGINE • 48 kHz / 32-bit float audio • 64-voice polyphonic sampler • Built on AudioKit • Effects: reverb, stereo delay, master limiter VISUALIZATION • Real-time FFT spectrum analyzer • Metal-powered retrowave audio-reactive visualizer • Waveform display for sample editing Whether you're a beat maker, a jaw harp player, or an electronic music explorer — Jaw Harp Synth bridges ancient acoustic tradition with modern digital production.
Synesthesia Synth
An experimental audio-visual instrument that allows users to sculpt evolving spatial audio by manipulating floating capsules. Position, rotation, and pulse changes affect tone, texture, and synchronized particle generation. It's a visual synthesizer, not a game.

Synthaestesia is a free experimental audio-visual instrument. Three capsules float in space. Every contraction produces sound. Move them, rotate them, reshape their pulse — and sculpt evolving spatial audio. Position changes tone. Rotation alters texture. Delay generates synchronized particles. This is not a game. It’s a spatial synth you can see.
