Samples
The SU10 stores up to 48 samples. A
sample
is a digital recording of an acoustic
waveform (or two waveforms, if stereo), together with playback parameters that
determine how the sound is played: the type of loop applied, the direction of
playback, the start and end points, and so on. The following conceptual diagram
shows how a sample exists within a typical sampler.

How a Sample is Made
A sample is created by taking digital “readings” of an acoustic analog signal at a
very rapid rate. The resulting binary values indicate the state of the acoustic wave
at each point of reading. The sample can be replayed by reconverting the values
to an analog wave.
