“SR”
“SR” stands for “Sampling Rate” - the frequency with which the Sample is read. If the
Sampling Rate is modified, the sample pitch is also proportionally modified. For exam-
ple, if the “SR” value is raised, the sample pitch will also become higher.
Basically, this function provides a fine tuning for the sample, avoiding dissonance
between the samples that make up the Waveform.
“Length” (cannot be modified)
Length of the sample in words. In this case, word is the measuring unit of the sample.
Since the S Series uses a 16-bit sampling technique, a word is composed of 16 bits
(corresponding to 2 bytes).
Therefore, to calculate the length of the sample in bytes, multiply the number shown on
the display by 2*.
“Loop Start” & “Loop End”
These parameters modify the “Loop Start” and “Loop End” points. Any one of the eight
loops of the sample can be selected by pressing the “Loop nr:(x)” command the required
number of times.
The S Series uses only the first loop, but Sample Translator can also modify the other
loops, acting as an editor for samplers.
Access your changes with the
ENTER
, and insert the desired value with the
DIAL
or the
numeric keypad. The value inserted will be expressed in words.
The “Start” and “End” points must lie within the limits of the sample. The maximum
value that can be given to “Loop End”, therefore, coincides with the length of the sample.
For example, if the “Length” parameter indicates a value of 40000, the maximum value
that can be given to “Loop End” is 40000.
Why the loop limits should be modified The loop very often produces a troublesome
“click” every time the cycle is repeated. This is caused by the difference created between
the end of one loop cycle and the beginning of the next one:
“click”
The extreme points of the loop should be modified so that the amplitude at the “Start”
point” is matched as precisely as possible to the amplitude at the “End” point, so that the
“click” can be heard only very faintly or disappears entirely.
When the loop extremes are modified, you should bear in mind that a loop which gives
excellent results, for example, in the central part of the keyboard, can be unsatisfactory in
other extensions. This is yet another reason why the multi-sampling technique should be
used.
