Chapter 10 Track and Phrase Editing

Track Time Compression/ Expansion

This operation allows you to expand or compress the playback time of a track or a group of tracks by a specified time. You can specify the amount of time compression or time expansion in a range of 75-125%, but the more extreme the setting, the more the sound quality may be affected. We recommend you try to keep the compression and expansion within a range of 93-107%.

Example 1: Compression

4.Press the Track STATUS button to specify the track to be time-compressed or -expanded. The STATUS button turns red, indicating it is the track to be edited. You can press more than just one STATUS button if you wish to edit more than just one track. If you press a STATUS button and then change your mind, press it again to change it back to green.

*If you want to select TR 1-12, press [FADER/MUTE] several times until the “TR” indicator lights.

If you want to select TR 13-18, press [FADER/MUTE] several times until the “TR” indicator blinks.

*Track Compression/Expansion creates new performance data with a different playback time. For this reason, it cannot be executed if there is not sufficient space on the current drive.

*It is not possible to use Time Compression/Expansion when the elapsed time from the Start Point to the End Point or from the Start Point to the To Point is less than 0.5 seconds.

*Do not time compress audio to a period of 0.5 seconds or shorter. Any sound 0.5 seconds or shorter will not be played.

1.Hold [SHIFT] and press [F2 (TRACK)].

2.Make sure “Track Edit Menu” appears in the display. If it does not, press [F1 (Tr/Ph)] once.

3.Press [F3 (CmpEx)].

If you don’t see “CmpEx” above [F3], press [PAGE] until “CmpEx” appears, and then press [F3 (CmpEx)].

5.[ ], [ ], [ ], and [ ] to move the cursor. Set the START and END values.

A quick way to enter edit points (START, END, FROM, and TO) is to create a locator for each edit point (p. 43) before entering the edit screen. Then go to the desired edit screen (such as Erase, Copy, Cut). You can enter your edit points by pressing a LOCATOR button and then holding [SHIFT] and pressing [LOC 1] to enter that point as the START time, [SHIFT] + [LOC 2] to enter that point as the END time,

[SHIFT] + [LOC 3] to enter that point as the FROM time, or [SHIFT]+ [LOC 4] to enter that point as the TO time.
