Chapter 10 Jobs 267
CHAPTER 10
<FREQ. CONVERT>
Use this job to decrease the waveform sampling rate. This will produce a rougher
sound that you may find more suitable for certain types of sequences. This operation
will also reduce the size of the waveform data, thereby increasing the amount of free
memory available for additional sample recording.
The sampling rate refers to the number of frames (data readings) per unit time. For
general information about sampling rates, see page 151. For an explanation about
how to set the sampling rate when recording a sample, see page 158.
After processing the waveform, the SU700 gives you a chance to listen to the results
to determine whether you wish to keep the change. If you are not pleased with the
sound you can cancel the job and retain the original waveform.
Note that it is only possible to reduce the frequency; you cannot choose to increase it.
Specifically, the following conversions are available (where rates are in kHz):
Original Freq. Target Freq. (as shown on screen)
48.0kHz 24.0kHz (24K)
44.1 22.05 or 11.025 (22K, 11K)
32.0kHz 16.0kHz (16K)
22.05 11.025 (11K)
Procedure
Be sure that you have selected the song containing the sample(s) you want to work on.
1.
Press SAMPLE | PROCESS.
▼ The track brackets indicate the currently selected sample track. The screen briefly
displays PROCESS, and then displays the name of the last process job that you se-
lected.
2.
If the screen displays a job name other than FREQ. CONVERT, turn the dial so that
the name changes to FREQ. CONVERT. Then press [OK].
3.
Select the track containing the sample you want to work on by pressing the appropri-
ate bank selector and/or pad.
NOTE:
If you select an empty track, the screen displays
NO SAMPLE
. If you select an irreduc-
ible frequency, the screen displays
IMPOSSIBLE
, indicating that it is not possible to re-
duce the frequency.
