Frequently Asked Questions

Q: Do I need stem separation for MIDI conversion?

A: For single instrument recordings, you can directly convert to MIDI. For complex mixes, we recommend isolating the instrument track first.

Q: Is it really free?

A: Yes! You can convert up to 3 files/week on our free plan — no payment info needed. PRO unlocks unlimited usage and more advanced options.

Q: Which instruments work best?

A: Pitched or harmonic instruments (e.g., piano, guitar, melody vocals) give the best results. Highly polyphonic or percussive parts can be more challenging.
