Current limits
- Single melody only. Chords and overlapping notes are not reduced for you; you will be asked to pick another track or remove notes in the editor.
- Notes must start on a sixteenth-note grid. Triplets and unquantized playing are reported, not silently rewritten.
- MIDI converted from audio usually needs quantizing and cleanup in the MIDI editor first.
- Time signature changes are not supported. A key change is written in one key. Lyrics and repeat signs are not written.
MIDI to jianpu FAQ
Is it free? Do I need an account?+
It is free and needs no account. Converting and downloading happen in your browser and use no credits.
Can it convert chords or two-handed piano?+
Not yet. It writes a single melody. If the melody has its own track, choose that track; otherwise remove the other notes in the MIDI editor first.
Why does it say notes are off the grid?+
The file has triplets or unquantized playing. We do not change the rhythm silently, so quantize it in the MIDI editor and open it again.
How is the key chosen?+
From the file's key signature when it has one, otherwise estimated from the notes. An estimate can be wrong, so check it against your score; you can change it. Minor keys use the relative major, so A minor is 1=C.
Can it convert a staff notation image or PDF to jianpu?+
Not in one step. Use sheet music to MIDI first, then open the MIDI here. The recognized file may contain chords and may not keep the key or time signature, so check them by hand.
Can I export a PDF?+
Not yet. PNG only for now.
