8.3.4. Exporting a Whole File (Audio and MIDI Together)

Qtractor can export all of a session's audio clips as one audio file, but it cannot export the MIDI clips directly into that audio file. This is because Qtractor does not synthesize audio from MIDI signals, but uses an external MIDI synthesizer to do this. Thankfully, there is a relatively simple way to overcome this, allowing both audio and MIDI to be exported in the same audio file: use Qtractor to record the audio signal produced by the MIDI synthesizer. This procedure only works if you use a MIDI synthesizer (like FluidSynth) which outputs its audio signal to JACK.
  1. Create a new audio track in Qtractor by clicking on 'Track > Add Track'.
  2. Ensure that your MIDI synthesizer is set up correctly to produce output in the usual method (through your speakers).
  3. Use Qtractor's "Connections" window (press F8 on the keyboard) to ensure that the output from your MIDI synthesizer is routed to the input for the newly-created audio track.
  4. Move Qtractor's transport to the start of the session.
  5. Ensure that only the newly-created audio track is armed for recording.
  6. Arm Qtractor's transport for recording.
  7. Press "Play" on the transport, and wait as the session plays through.
  8. When you have reached the end of the session, stop the transport. Qtractor will not automatically stop the transport.
  9. Export the file as you normally would by clicking 'Track > Export Tracks > Audio'.
After the audio version of the MIDI signal is recorded, and you have exported the session, you may wish to delete the new audio track.
