Creating Sounds and Effects
4-11
After Touch and Breath Sources correspond to pressure-type controllers on the
MIDI instrument. After Touch produces output based on how hard the keys of a
MIDI controller are pressed down after the initial velocity. Breath produces
output based on how hard you blow into a wind controller. Minimum pressure
generates 0 and maximum pressure generates 127. Note that these controllers
differ from other MIDI controllers in that they are “return-to-zero” controllers.
Their output will always cycle smoothly from 0 to some higher value (correspond-
ing to the maximum amount of pressure applied to the controller) and then return
to 0 again. Use After Touch and Breath to control parameters that will produce
audible changes in the sound of an effect as it is processing audio. MIDI Pressure

MIDI Note numbers
The Note Number Sources produce output based on the note played on the MIDI
instrument. For reference, Note Numbers are shown here as they correspond
to a MIDI keyboard, but they can also be generated from non-keyboard devices
such as sequencers, guitar, wind and percussion controllers. Use Note Number
controllers to control parameters that you want to vary within the pitch range of
the control Source. (For example, a keyboard-controlled auto pan.) There are
three different types of Note Number control Sources on the LXP-15 II: LastNote,
LowNote, and HiNote. LastNote generates output based on the last note played.
LowNote is similar to LastNote except that when more than one note is played
at once, it generates output based on the lowest note played. HiNote is the same
as LowNote, except it generates output based on the highest note played when
more than one note is played at once.
