When the Preview Player appears, you can listen to the selected file directly within the
Browser. To start file playback, double-click on the file in the Browser or click on the Play
button in the Preview Player with the desired file selected.
Preview Player playback is independent of the main Song playback, so you will notice the
playback-position cursor does not move across the Arrange view while previewing a file. The
Preview Player has its own playback-position indicator that moves left to right to indicate the
current playback position in the selected file. The position indicator can be clicked-and-
dragged to navigate through the selected file during playback. A volume fader controls the
playback level of the Preview Player.
Preview Player playback can be synced to Song playback to allow auditioning of files along
with Song playback. Click on the Play at Song Tempo button, which is engaged by default, to
allow the Preview Player to sync to the current Song tempo.
If the currently selected file's tempo is known, and Play at Song Tempo is engaged while
previewing, the file will be timestretched on the fly to match the current Song tempo. To
preview while hearing your Song, start Song playback first, and then select a file and preview
it.
To loop the selected file during preview playback, click on the Preview Player's Loop button,
which is engaged by default. Looping during preview playback makes it easy to listen to the
selected file in the context of your Song.
An easy way to audition many audio loops from a single folder, such as a loop library, is to set
the left and right locators around the range of the Song into which you will import the loop,
then loop playback in the Transport within that range. Next, preview the first loop in the folder
and then use the up and down arrow keys on your keyboard to cycle through every loop in
that folder.
7.2.3 Import an Audio File into Your Song
Importing an audio file from the Browser into your Song is as easy as clicking on the file and
dragging it into the Arrange view of the Song. When the file is dragged to empty space, a
mono or stereo Audio Track will be created with the file placed on it as a new Audio Event,
located at the position to which it was dragged. When the file is dragged to an existing Audio
Track, it will be placed as a new Audio Event on that Track, at the position to which it was
dragged. If you import a stereo file to a mono Track, the Event created will be stereo, but the
output will be mono, since the Track is mono. If you import a mono file to a stereo track, the
output will be dual mono, that is, the same signal equally on both sides.
