Note that the quality of the recording improves as the rate of reading — called the
sampling frequency — increases. Although higher sampling frequencies give bet-
ter quality, they also consume more memory and therefore reduce available re-
cording time. The maximum sampling rate available on the SU10 is 44.1kHz,
identical to the rate offered by a conventional CD.
Because samples require considerable memory per unit of time, they are generally
kept quite short. The replay time of a sample can be extended to an arbitrary
length by setting up a loop, so that the sample repeats indefinitely.
The term sample is also used in a technical sense (its original sense) to refer to each “reading” of
the acoustic signal, as described above. Within this manual, however, the term always refers to
the entire recorded waveform together with its related parameters.
Banks and Pads
You play the SU10 samples by pressing buttons, or
pads. The SU10 has twelve
pads. Because the SU10 can store up to 48 samples, however, it also has four
banks. You choose a sample by selecting the appropriate bank, then pressing the
corresponding pad.
