Convert a MIDI Track to an Audio Track - Pro Tools


Why would you want to convert/record a MIDI track to an audio track?

  • To conserve computer resources. Once the MIDI track has been converted to an audio track you can remove any MIDI instrument plug-ins from the converted track/s.
  • When sending a session or track to someone who may not have the same plug-ins and or samplers.
  • The types of MIDI instrument plug-ins you have installed may change over time. If you re-visit an old mix it's possible you may no longer have the MIDI instrument plug-ins you had installed when you originally did the mix.

Convert/record a MIDI Track to an Audio Track:

  1. Verify the original MIDI track volume levels. Ensure the track meter is NOT "clipping" in the red. A good starting level might be occasional peaks in the yellow of the tracks meter's. If the track level is to high consider turning down the output level of the MIDI instrument plug-in.
  2. Set the MIDI tracks pan control/s as you desire.
  3. Create a new "Audio" track. If the track to be converted is stereo create a stereo Audio track, if mono create a mono Audio track. To create a new audio track: Press and hold down the Ctrl + SHIFT keys then press the n key on your keyboard.
  4. Position the new Audio track directly below the original MIDI track in the Edit window.
  5. Name the new track for example, piano.cnvrt or piano.print. Naming the track to describe that it is NOT the original can be useful if you re-visit/mix the tracks at some time in the future.
  6. Set the output of the MIDI track to be converted/recorded to an open bus. See image below.
  7. Set the input of the new track (where MIDI will be recorded) to the same bus used for the output of the MIDI track. See image below.
