The Algorithms and Their Parameters
Mod: Latch
The latch is a very flexible modulation source. It can be used to do such things
as derive a switch from a continuous “return to zero” source (like MIDI After
Touch). It can turn a momentary (on/off) footswitch into a latching footswitch
(push on/ push off), and it can divide the switching rates of sources in half or
thirds.
Modulation cont'd.
The latch has three parameters: Src, High and Low. Any patch source can be
the Src (See Source listing under Patching.) High and Low are threshold
values. The latch works as follows:
There is no output from the latch until the Src value falls within the range defined
by the settings of High and Low. While the source value is between these
thresholds, the output of the latch is the same value as the source. When the
source value reaches or passes either threshold, the output of the latch holds at
the limit value until the source value passes through the threshold twice. The
latch can be set to hold at either the low threshold, the high threshold, or both.
Setting Low to 0 disables latching at the low threshold. Setting High to 127
disables latching at the high threshold.
