Sample-And-Hold (S&H) Settings - Alesis Micron Reference Manual

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

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