Growl Control Source: The Growl Control Source is used to set the type of
MIDI control change message that controls the “growl” component of the
instrument’s sound. Three options are available: Velo (Velocity), BC (Breath
Controller) and AT (Aftertouch). Only one type of MIDI control change
message can be used at a time.
Growl Control Response Curve: This setting workl just like already described
for the Amp, Brightness and Reverb Control Response Curve.
Growl Maximum Depth: The Growl Maximum Depth control sets the maximum
volume level of the growl component of the instrument's sound. Note that this
control works in conjunction with the Growl Deviation control (described
below). If the Growl Deviation control is set to 0, then the level of the growl
component of the instrument's sound is determined by the setting of the Growl
Maximum Depth control. If the Growl Deviation control is set to a value other
than 0, then the level of the growl component of the instrument's sound will
randomly vary between 0 and the current value of the Growl Deviation control
for each note that is played.
DEV (Growl Deviation): The DEV (Growl Deviation) control is used to set a
degree of randomisation in the “growl” component of the instrument's sound.
Increasing the DEV (Growl Deviation) control will introduce more random
variation in the amount and tone of the growl component of the instrument's
sound from note to note.
Three MIDI controllers are available for modulating SaxLab 2’s various
Performance parameters. These are: Velo (Velocity), BC (Breath Controller)
and AT (Aftertouch). Each controller works in a slightly different way. Note
that only one type of MIDI control change message can be used for each
Performance Control at a time.
Velo (Velocity): All MIDI controllers have the ability to trigger a note. This is
usually done by transmitting a MIDI Note-On message. Note-On messages
consist of three bytes: a Status byte and two Data bytes. The second Data
byte contains the velocity at which the key was pressed. In most cases, key
velocity is used to determine the loudness of the synthesized sound. Note that
only one Note-On message is transmitted for each note that is played.
BC (Breath Controller): MIDI Wind controllers typically transmit breath
pressure information as MIDI Breath Control messages. Breath Controller
messages consist of three bytes: a Status byte and two Data bytes. The
message's first Data byte defines the type of Control Change message (in this
case, Breath Control), which has a value of 0x02. The second Data byte
determines the current output value of the Breath Controller.
Note that new Breath Controller messages are transmitted whenever the
controller's input changes, so that Breath Controller messages can vary over
the duration of a note. Also note that MIDI keyboards normally do not transmit
Breath Controller messages, however it is usually possible to reassign the
output of other MIDI controllers (such as the Mod Wheel) so that they transmit
MIDI Breath Controller messages.
