<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 irreducible frequency, the screen displays IMPOSSIBLE, indicating that it is not possible to reduce the frequency.
