MODIFIERS & CONTROLLERS

Doc Q7.0
Pitch Detector
7.3.5
The
Pitch Detector
has no menu page or parameters, but appears in all modifier screens as a source.
This module monitors the main input signal and analyzes its pitch, outputting a low value for low notes
and a high value for high notes.
Manual Knobs
7.3.6
New to the Axe-Fx II are four front panel Quick Control knobs, detailed in section
on p.
. When
you select the MANUAL page of the
menu, these knobs work as MODIFIER control sources
that can be used for making sound adjustments without menu diving. The current value of each knob
is saved with each preset.
Remember that while you are setting up a MODIFIER, the Manual knobs will be assigned to edit
parameters on the screen instead of operating as SOURCE. To test your modifier, you’ll need to leave the EDIT
menu and return to
MANUAL to test your work.
Scene Controllers
7.3.7
Scene Controllers are similar to Manual Knobs above in that you manually set the value for each of two virtual
knobs that can be assigned as SOURCES for modifiers. Unlike Manual Knobs however, the value of each SCENE
controller can be pre=programmed individually for each SCENE in each preset. See p.184 for more on SCENES.
For example, you might assign SCENE CONTROLLER 1 to delay feedback, with a value of 10% in SCENE 1, 30% in
SCENE 2, 0% in SCENE 3, and so on. SCENE CTRL 2 could meanwhile be used for something completely different.
External Controllers
7.3.8
The onboard
jack or any MIDI Control Change message can be
assigned as an
External Controller
to be used as modifier source, as
shown in the example in Figure 7-3. The Axe-Fx II allows you to set up
12 global External Controller assignments, but remember: you can use
each of these to modify multiple parameters per preset.
To set these EXTERNAL CONTROL assignments, use the CTRL page of
the I/O menu. Select the desired EXT CTRL entry and turn the value
wheel until PEDAL or the desired MIDI CC number is shown. Set an
External Control to NONE to disable remote control.
The Axe-Fx II also has a “learn” feature that allows it to detect
control sources automatically. Select the desired item, press ENTER,
and use the remote controller to send some data to the Axe-Fx II; the source will be set automatically. (This is also
a good way to ensure that remote devices are in fact set up and transmitting correctly.)
Remember that the
channel
of incoming CC# messages must match that of the Axe-Fx II under I/O:MIDI.
The Axe-Fx II uses a set of system parameters—
EXTERNAL CONTROLLER INITIAL VALUE 1–12
, located on the MIDI page
of the I/O menu (p.
)—to determine what value should be used for each External Controller between the time
when the Axe-Fx II is booted up and when external data is first received. Options are 0% or 100%.
