Omitting Unwanted Portions
of the Sample (Marker/Start
Point/End Point)
For each sample in the SP-404, you can specify the portion of that
sample's waveform data that will actually play.
The point at which the waveform data will start being played is
called the Start Point, and the point at which playback will end is
called the End Point.
If the beginning of a sample you recorded contains unwanted noise
or silence, you can set the Start Point to omit this portion. Similarly,
you can set the End Point to omit an unwanted portion at the end.

When you set the Start Point and End Point, the BPM (tempo)
will automatically be calculated and displayed according to the
newly specified duration. If this duration is several measures or
is less than one measure, the displayed BPM value may be half
or double. If you want to correct the BPM to the desired value,
refer to "Changing a Sample's BPM" (p. 33).
For some time settings (for example three beats), it may not be
possible to calculate or adjust the BPM value correctly.
