Local monophonic draft
MP3 to MIDI, then the piano roll
Decode an MP3 on this device, trace one clear melody for up to 30 seconds, and open the rough monophonic result in the same editor used for MIDI cleanup.
Choose a clear monophonic recording. The first 30 seconds become a rough melody draft in the piano roll.
Audio never leaves this device. This rough draft follows one dominant melody from the first 30 seconds. Chords, drums, vocals inside a full mix, and polyphonic arrangements are not supported.
Why this is not another AI wrapper
The rough melody draft opens in a piano roll that can quantize, transpose, reshape velocity, merge tracks, and check compatibility. The editable result is the value; the detector is deliberately narrow.
The file is not uploaded. Use a clear, exposed melody. Chords, drums, vocals inside a full mix, and polyphonic arrangements are not supported, so treat every result as a sketch.
Broader transcription waitlist
The local result is a rough monophonic melody sketch, not a complete-song transcription. Join AI Credits if you want to hear when a broader workflow is good enough to charge for.
