START POINT [StPnt]
Purpose: Sets the playback start point.
Values: 0,...,(127 less than endpoint)
To set: Touch the ribbon; or press or hold [–1], [+1].
Explanation
This function sets the sample’s start point. The selected point determines where
sample replay starts (for forward-direction play) or ends (for reverse-direction play).
A setting of 0 corresponds to the wave start point.
Note that you can change this value by touching the ribbon. (The leftmost point of
the ribbon corresponds to a setting of 0.) You may find it convenient to touch the
ribbon to get an approximate value, then press [+1] or [–1] for fine tuning.
If loop mode is set to Whole Loop or Reverse Loop, you can hear how the loop
sound alters as the value changes. Simply hold down the pad while changing the
value; the sample will continue to loop as the Start Point changes.
Also if loop mode is Whole Loop or Reverse Loop, the SU10 will display the
TEMPO indicator and current tempo at the bottom right of the LCD. The tempo
value will change as you adjust the START point. Refer to the “About TEMPO” box
for information.
About TEMPO
When you edit the start point or end point of a loop, the lower right of the LCD
displays the word TEMPO, and the meter area indicates a tempo value. The value is
an estimation of the tempo of the looping segment (in beats per minute), and can be
used as a reference for matching the timing of loops on different samples. The value
always falls between 80.00 and 159.99; the calculation is based on the assumption
that the loop segment consists of a regular number of “beats” (1, 2, 4, 8, 16, or so
on).
Note that the value applies to the looped part only. For a “Whole Loop” or “Reverse
Loop” sample, this is the area between the Start Point and the Loop End point. For
a “Partial Loop” sample, however, this is the area between the Loop Point and the
End Point.
In most cases the tempo is shown to the nearest hundredth of a beat, with an under-
score for the decimal: 124_34, for example, means “124.34 beats per minute.” For
reverse loops and very long forward loops, the calculation is shown to the nearest
full beat only: 124_—. No tempo is displayed for loops that are shorter than 0.375
second.
Because tempo calculation is based on the loop’s time length, the result varies ac-
cording to the current Grade and Pitch settings.
