13. Sample-and-Hold (S&H) settings<br />
The first three settings–TempoSync, Rate, and Reset–operate<br />
identically to the LFO settings listed above. Here are the<br />
additional S&H settings:<br />
Input<br />
The Input to the Sample & Hold determines the source of the<br />
S&H values. If the source is continuously active, like an LFO,<br />
there will be an endless supply of new values for the Sample &<br />
Hold to feed to its destination in the mod matrix. If the source is<br />
something more static like one of the wheels or pedals, the<br />
destination will receive new values from the Sample & Hold only<br />
after the value of the input is changed and another sample is taken.<br />
The inputs for the S&H generator are the same as the Modulation<br />
Matrix’s modulation sources (discussed later). See page 92 for a<br />
list of those inputs.<br />
Smoothing<br />
This parameter governs the abruptness of the shift from the value<br />
of one sample to the value of the next. A low smoothing value<br />
causes the sample values to change instantly from one value to the<br />
next when the new sample is taken. A high smoothing value<br />
causes the Sample & Hold to “slide” from one value to the next.<br />

What does Sample & Hold<br />
mean?<br />
Sample & Hold is a term that<br />
originated in the early days of<br />
analog modular synthesizers.<br />
It describes the process by<br />
which a reading, or<br />
“Sample,” is taken at regular<br />
intervals of a particular input<br />
source, such as an LFO. That<br />
Sample becomes a value that<br />
is fed to a destination, such as<br />
filter frequency. The<br />
destination parameter is held<br />
at this value until the “Hold”<br />
period has expired, at which<br />
time another Sample of the<br />
input source is taken and fed<br />
to the destination, and so on.<br />
S&H Smoothing<br />
With Sample & Hold<br />
smoothing set to very high<br />
values, it is possible that very<br />
little or no change may be<br />
heard at the destination. If<br />
you’re not hearing the<br />
desired amount of S&H, try<br />
decreasing the smoothing<br />
value.<br />
