178 Chapter 4 Audio in the Arrange Window

Scrubbing

You can scrub playback of a Region to accurately select a division point, by using the

Scissors tool and holding down the mouse button. This is only available on audio

systems that support scrubbing. When using this feature, the Scissors tool works like a

virtual playback head, which moves over the “virtual tape” (the Region). If you release

the mouse button, the region will be divided at the current position of the Scissors

tool.

Resolution

When selecting a cut point with the Scissors tool, you can move backwards and

forwards in steps of one division. If you need a finer resolution, press Control after you

have selected the Region with the Scissors. To obtain the maximum resolution (ticks)

press Shift, as well.

On Zero Crossings

If Edit > Search Zero Crossings is switched on in the Audio window, the division-point is

moved to the nearest position that the waveform crosses the zero amplitude axis.

When enabled, this also applies to all other methods of altering the start or endpoint of

a Region in the Arrange window.

Note: This can cause the precise startpoint and length of a Region to differ slightly

from the selected value. In most cases, this will be inaudible.

Erasing Regions

Regions can be erased by either; selecting them and pressing Backspace, or by clicking

on them with the Eraser tool.

Erasing Recordings

When you erase a Region that you have just recorded (since opening the song), Logic

will ask if you also want to erase the corresponding audio file. This is a good way to

avoid wasting hard drive space unnecessarily by retaining bad takes and unwanted

recordings.

If the recording was made before the song was loaded for the current session, this

dialog box will not appear. This prevents you from accidentally deleting valuable

recordings. Pressing Backspace will only remove the Region from the Arrange area. If

you want to delete the corresponding audio file from the hard disk, you can do so by

selecting Audio File > Delete File(s) in the Audio window.
