Sample & Hold (S&H)
Most of the Sample & Hold's parameters are identical to those of the
LFOs discussed on pages 45-46, so we will only list them and refer you
to those pages. There are some important distinctions, though, and we
will point those out.
S&H [edit]: Rate
Page:
1
Soft Button:
1
Range:
0.010 – 1000 hz or x 16 – x 1/16
Default:
0.100 hz
This is where the initial rate for the Sample & Hold is set. It determines
the length of time between samples. If the [s&h] button is selected, you
can edit the rate of the Sample & Hold by turning the rate knob. Doing
so will also take you immediately to this page.
For an explanation as to why there are two sets of values listed for this
parameter's Range, what they mean, and how to select between them, see
the section LFO [edit]: Rate on page 44. See also the sidebars on that
page for more information.
S&H [edit]: Sync
Page:
1
Soft Button:
2
Range:
tempo, off
Default:
off
This parameter determines whether the Sample & Hold is synchronized,
or "slaved," to the master tempo setting. For a complete description of
how that affects the function of the Sample & Hold, refer to the section
LFO [edit]: Rate on page 44 and the sidebars on that page as well.
S&H [edit]: Input
Page:
1
Soft Button:
3
Range:
see table
Default:
global random
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.
On the next page is a chart that documents the Sources that are available
as Inputs to the S&H generator.
Program Parameters
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.
In order to use S&H as a modulation source,
you must use the mod matrix to designate a
parameter as its destination. For more
information, see Chapter 6.
