Real-time Control

The Data Entry Control is a stepped, variable control switch used to change
parameter values. The wheel increments or decrements the current value
one unit with each click. This control incorporates acceleration, which
advances the value faster if the Data Entry Control is turned quickly.
The Real-time Controller Knobs serve three purposes:
Real-time control of synthesizer parameters
1.
"Quick Editing" the initial settings of the real-time controllers
2.
"Deep Editing" the parameters
3.
This section describes each of the three uses.
The Real-time controller knobs provide direct control of the Xtreme Lead's
synthesizer parameters. They are always active when on the Preset Select
(main) screen. They can optionally be used to transmit MIDI controller
messages to other MIDI devices.
The Control button (left of the knobs) changes the function of the real-time
controller knobs. Each time the button is pressed, the Control Mode toggles
to select one of the three Control Row groups. The currently selected
Control Row is indicated by the illuminated LED to the right of the button.
The control knob functions are determined by the selected Control Row.
The three Control Rows generate MIDI data that can control the preset on
the current MIDI channel (the channel showing on the Preset and main
screen. The labels (Filter Cutoff, Filter Res, Shape, Image, etc.) printed on
these rows show how the factory ROM presets may be programmed to
respond. (The controls might not conform to the front panel labels depending on
the preset.) You can change the way a preset responds to MIDI A-L messages
from the Edit menu (PatchCords).
There is an LED next to each of the control knobs which illuminates to
indicate that the knob setting has been changed from the value
programmed in the preset (when Quick Edit mode is enabled). If the knob
position is returned to the original setting, the LED is extinguished.
If the "Knobs MIDI Out" parameter in the Master menu (see "Knobs/Riff
MIDI Out" on page 86) is set to "transmit," the system sends a MIDI
controller message when you turn off the Control knob. The MIDI
controller message is sent on the current MIDI channel (also called the
basic channel) using the controller number assigned in the Master menu
(see "Real-time Controller Assignment" on page 83).
The knobs only generate a message when you move a knob to a new value.
The current value jumps to the new value.
