Kanade.
Music with no wrong notes.
A highly specialized web synthesizer and AI duet composer. By mapping keys dynamically to curated cultural scales like Hirajōshi, Kanade guarantees perfect harmony with every keystroke while generating structured melodic responses.
The Frustration
Choice Paralysis & Discord: Confusing 88-key layouts make it hard for beginners to improvise, often resulting in dissonant, painful chords.
Wandering AI Music: Standard neural music generators often produce unstructured, wandering melodies without coherent motifs.
Heavy Downloads & Servers: Most web synths rely on downloading massive sound libraries (gigabytes of samples) or slow cloud processing.
The Plan
- Lock the keyboard dynamically to beautiful scales (Major Pentatonic, Hirajōshi, Diatonic) so **every mash sounds amazing**.
- Design a **First-Order Markov Chain** composer trained on folk melodies to structure 4-bar response loops.
- Synthesize sound waves using **native Web Audio API** node graphs, pitch-shifting it to 432 Hz.
- Export WAV files directly via the browser, and bit-pack notes into **Base64 URL parameters** for database-free sharing.
Zero-Frustration
Scale Mapping
Kanade dynamically binds your physical keyboard keys to curated, chord-safe musical scales. Switch from standard Diatonic to the bright Major Pentatonic or the traditional Japanese Hirajōshi scale. With wrong notes mathematically excluded, you can focus on rhythm and flow.
Bilingual Markov Composer
We trained a structured Markov Chain algorithm on real-world folk motifs. When you swap scales, the AI composer swaps its musical corpus—matching Western themes on Major keys, and swapping to traditional Koto folk patterns when using Japanese scales.
Real-Time AI Duet
Jam Accompaniment
Enable AI Duet mode and play standard melodies. When you stop, the AI composer intercepts the last note, analyzes your tempo, and instantly generates a structured 4-bar phrase response in real-time, functioning as an active collaborative partner.
Web Audio Synthesis & Warm Tuning
No large sample libraries to download. Kanade constructs its audio graph (oscillators, biquad filters, dynamic gains) directly using the browser's Web Audio API. Instrument profiles simulate the resonant tones of a Marimba, Chimes, and a plucked Japanese Shamisen—all mathematically tuned to the warm 432 Hz healing frequency.
Zero-Server WAV Exporter
Bake and render your compositions in milliseconds. By routing synthesized node data through an `OfflineAudioContext`, Kanade processes, writes PCM headers, and downloads a studio-quality `.WAV` file entirely within the client's browser, bypassing backend processing limits.
Ultra-Compact URL Sharing
Share your compositions without a database or server storage. Kanade packages notes, timestamps, scales, and velocities using custom binary bit-packing, serialized into a compact Base64 parameter appended to the URL. If someone clicks your link, their browser decodes and plays it instantly.
