COMMENT: An example of a good use of this function is to
prevent channel pressure data from being recorded into your
tracks. If you are using a keyboard that produces channel
pressure messages, all of these continuous messages will
normally be recorded into the track, whether your synthesizer
uses them or not. This will cause a lot of extra sequence
memory to be used and will cause the sequencer to work
much harder to play all of these messages, possibly causing
note delays. To avoid this, turn off the recording of continu-
ous controller messages unless your synthesizer is using
them. To do this, select

all continuous controller event types, meaning that large numbers of
these individual events are used to simulate a gradual change in the
specified parameter. For example, when you move a pitch bend
wheel on a keyboard, a large number of pitch bend events are
output from the keyboard, and all of them are recorded into the
active track. The problem with recording all of these events is that
they use a large amount of memory and they cause the internal
computer to work very hard, causing possible timing delays if large
amounts of these events exist in a sequence. In many cases,
however, many more of these events are output from the keyboard
than are necessary to produce the desired effect.
