# Preparing External MIDI Tracks

Before you can mix down the song, any MIDI tracks using an External MIDI Instrument have to be recorded to one or more audio tracks. To do this you should:

- Connect your synthesizer's output to your Audio In Device.
- Switch the MIDI track(s) to playback mode. Mute all other tracks.
- Add a new audio track and switch it to record mode.
- Start the transport and stop it when the entire MIDI track has been played.

You can now use the audio tracks instead of the MIDI tracks. To make the audio tracks sound just as loud as the original tracks did, you can adjust the Volume fader while switching between the tracks using the Solo or Mute buttons.
