About the audio tracks
The audio tracks used by a song (Audio Track 1, 2) are a single stereo WAVE file that is created by recording in synchronization with the MIDI tracks + master track.
Audio track 1 is the L channel of the stereo WAVE file, and audio track 2 is the R channel.
When you record or edit one track (or any portion of a track) this entire stereo WAVE file is modified; it is not the case that sepa- rate WAVE files exist.
This means that an unrecorded track or region of a track will contain data with a waveform level of “zero.” In other words, the size occupied by the stereo WAVE file is the same whether or not recorded data exists.
Some examples are shown below to illustrate this. These examples will help you use the HD Audio Track function and your hard disk space most effectively.
1For this example we will assume that the song is 16 measures in length. From the initial state of the song, suppose that you record guitar on audio track 1. A stereo WAVE file will be created. The length of the stereo WAVE file will be the length from the beginning of the song to the location at which you stopped recording. The unrecorded audio track 2 will also occupy space on the disk.

3You record a vocal from the beginning of audio track 2. The stereo WAVE file will be updated as shown in the diagram. The space occupied by the stereo WAVE file has not changed from the state shown in step 2, above.
