To upload an example track you will need to include the example track when you upload your track to be mastered to the FTP folder. Include both your pre-master and the reference file
In the FTP Folder tab, select the track you wish to be submitted for mastering.
In the Reference Tracks tab, select your relevant reference file
You can then complete your order on the Order Mastering tab and send our engineers any specific notes on your order.
Note - Make sure that you do not order the example track to be mastered, and state in the notes that that track is an example track for reference only.
