How to render a MIDI file

A MIDI file is a set of instructions, not a sound. Getting it to sound like an actual instrument normally means a sample library, an articulation map, and a lot of patience. Here it means choosing an instrument.

  1. Add your MIDI file: Drop a .mid or .midi, single- or multi-track. Each MIDI track lands on its own track.
  2. Choose the instruments: Fifteen modelled players, a different one per track if you like: saxophones, brass, strings, winds, keys, guitars, drums and voice.
  3. Play it back: Performed rather than triggered, with velocity read as timbre, and bounced to WAV, MP3 or FLAC.

Pick the instrument

Each has its own page and a demo: the same melody, written as MIDI and rendered by that instrument.

Questions about the MIDI to audio converter?

We have answers.

What MIDI files work?

Standard MIDI files. Multi-track files can be rendered per track with a different instrument on each.

Can I use my own instrument that is not on the list?

The list covers the model's trained vocabulary. If something is missing it is a training question, not a settings question, and worth asking for.

Does it follow velocity?

Yes, and as timbre rather than volume, which is the difference between a rendered part sounding played and sounding triggered.

  • Why MIDI playback usually sounds fake

    General MIDI playback sounds synthetic because it triggers one recorded note per pitch and transposes the rest. Real instruments do not work that way: a trumpet at the top of its range has a completely different timbre from the same written pitch played softly in the middle, and a violin changes character entirely between a slow bow and a fast one.

  • Fifteen instruments

    Strings, brass, woodwinds, keys, guitars, voices, drums and synths, including the articulations that matter, like pizzicato as a genuinely different instrument from arco rather than a filter on it, and muted trumpet as its own voice.

  • Dynamics are a timbre, not a volume knob

    Playing louder is not the same as turning it up. A forte note has more high-frequency content and a different attack, which is why turning up a soft sample never sounds loud; it sounds like a quiet recording played loudly. Dynamics here move timbre, not just level.
