Track markers can be used to line up sounds and loops or note important events. Each tracker marker can have a name. Track markers can optionally represent a "CD Track Marker" which will cause Mixcraft to render out a new track when doing a multi-file mix down or start a new track when burning a CD. Use track markers to:
q Create an audio soundtrack for a video, by adding a track marker for each important video event.
q Sync up loops and sounds. Zoom in and line up each sound to an exact millisecond.
q Burn a mix CD in Mixcraft
q Create a mix CD from exported WAV files so that each track marker represents a new track.
Add Track Marker…
To add a track marker, either double click on the timeline or right click and select "Add Marker". Give you marker a name and optionally uncheck the "CD Track Marker" if you don’t want this marker to start a new CD track.
Edit Marker / Edit Nearest Marker…
This brings up the edit marker window which lets you fine-tune the marker location, change its name and whether it’s a CD track marker or not. Once in this dialog, you can adjust all markers by using the Prev and Next buttons to go to and from subsequent markers.

ISRC Codes (For advanced users)
If your intention is to burn an audio CD for commercial use, you may need to enter in your ISRC codes. After you’ve been issued your ISRC code, click the ISRC checkbox and type in the code for each track.
The track marker wizard is a handy way to add multiple track markers at a time. You can either choose to add markers at specific intervals, or you can add markers based on the silence in a sound. It will even remove the silence! This can be very handy if recording albums from the Internet, LPs or cassettes and need a quick way to break up the tracks!
Before: We have one large sound with gaps between tracks.

After: We have 7 track markers and 7 sounds. (The silence has been removed)

All you have to do after that is to rename all the track marker names and then click "Burn CD" from the "Mix" menu.
