Turn a melody into MIDI. Upload a hummed, whistled, sung, or single-instrument recording and Solmi tracks the pitch and exports a standard .mid file you can open in any DAW — all in your browser, with no upload and no signup. It works one note at a time (monophonic), so it's built for melodies and leads, not full mixes or chords.
Upload an audio file of a single melody — a hum, whistle, sung line, or a lead instrument. Solmi tracks the pitch over time in your browser and builds a standard MIDI file you can download and open in any DAW. Nothing is uploaded; it all runs on your device.
No — this is a monophonic converter, meaning it transcribes one note at a time. It's great for melodies, vocal lines, basslines, and leads. Full mixes and chords (polyphonic transcription) need much heavier AI models and aren't supported here. For the cleanest result, give it a single, clear voice or instrument.
MP3, WAV, M4A, AAC, OGG, and FLAC — any format your browser can decode. The output is a standard .mid file.
Yes, completely free with no signup and no watermark. The converted MIDI downloads directly to your device.
Open it in any DAW (Ableton, FL Studio, Logic, GarageBand, etc.) to change the instrument, fix notes, harmonize, or build a full arrangement around your melody. You can also use it as a starting point and then turn the finished song into a music video with Solmi.
