# Realtime Mixdown

Some sample-based instrument plugins can suffer from audio dropouts during offline mixdown. This typically happens when the samples do not fit into the computer's memory. In such cases, realtime mixdown can be used to record a master file.

Follow these steps to record a master file in real time:

- Add a new track with an audio file (for instance: Mix.wav).
- Click the small arrow next to the track's Rec button and select "Master Out". This will make the track record the output of the master section instead of your soundcard's inputs.
- Switch the new track to record mode using the Rec button. Make sure all tracks that should be included in the master are in playback mode.
- Start the transport, and stop it when the song has reached the end.

You can now select the desired part of the recorded track in the track editor and export it using the Export option.
