Harmonic Precision for Modern Music Creators
Easily adapt melodies, chord progressions, and audio samples into any musical key.
Circle of Fifths Harmony
Seamlessly move up or down perfect fourths, fifths, and relative minors while preserving natural acoustic instrument overtone series.
Automated Interval Mapping
Choose any source root (C to B) and destination root. The engine calculates the optimal chromatic direction without forcing manual semitone math.
Lossless Audio Processing
Export clean, uncompressed 16-bit PCM WAV masters directly from your browser memory with zero uploads to remote servers.
Real-World Applications for Musical Scale Conversion
A must-have utility for producers combining multitracks from disparate sources.
Aligning Multiple Loop Samples
Take a guitar riff in E Minor, a vocal chop in G Major, and a piano chord progression in C Major, and convert them all into a unified target key signature seamlessly.
Transposing Instruments Adaptation
Quickly convert a concert C backing track into Bb or Eb scales so saxophonists, trumpeters, and clarinettists can sight-read sheet music easily.
Songwriting Modulation Testing
Test final-chorus key modulations (such as the classic truck-driver modulation up a half-step or whole-step) before committing to studio re-tracking.
DJ Harmonically Compatible Blends
Transpose tracks between Camelot wheel keys (e.g. converting an 8A track to 9A) to execute harmonic mixes with zero musical clashes.
