• Can I convert multiple MIDI tracks into audio files?

  No! Currently we only handly single MIDI file conversion. Nonetheless, we are constantly improving our prodcuts, so if we see a demand in multi-track conversion we'll invest into it and handle multi-track MIDI files perfectly where all tracks will be converted and mixed into a single audio file while preserving the original arrangement.
