Editing the sample of a pad
Expanding and Compressing a sample
to modify the length or tempo
If you want the tempo or length of samples to match, you can stretch or shorten the
time that the sample is played.
Matching the tempo to another sample—Tempo Match
It is easier to edit your song if the materials you collected are of a consistent tempo.
The CDX-1 makes it easy to match the tempo of different samples.
Since this function needs to accurately calculate the tempo in order to perform a
high-quality compression or expansion, you must first perform the procedure of
“Displaying the correct tempo of a sample” (p. 77) to specify the number of
beats in the original sample.
In the case of samples for which it is difficult to calculate a tempo, such as a
narration, vocal part, or a long sustained sound, set the number of beats to 0.
1. Press PAD RECORDING [TEMPO MATCH].
fig.33-06
The Tempo Match Setting screen appears.
2. Use CURSOR [ ] [ ] [ ] [ ] to select the pad bank number and pad
number for each item, specifying the desired number for each.
Turn the TIME/VALUE dial to set the pad bank number. To set the pad number,
either press a pad or turn the TIME/VALUE dial.
BasePad: Specify the sample that is the standard for tempo.
Source: Specify the sample you wish to expand/compress sample.
To: Specify the pad to which the newly created sample is assigned. (*)
* If the destination pad already contains a sample, a message of “Overwrite?” appears. If it is OK to
overwrite the existing sample, press [YES/ENTER].
3. When you have finished making the settings, press [YES/ENTER].
After a while, the newly created sample is assigned to the destination pad.
4. Press [DISPLAY] to return to the Basic screen.
•Compression/expansion
(Stretch) requires more
processing time than other
sample editing operations.
Also, the audio quality of the
stretched sample may be
inferior to that of the original
sample.
•In case the expanding/
expanding level is in excess
of 130% or less than 70%, the
sample will not be made
correct tempo.
