Delete screencontrols in MainStage
If you decide you no longer want a screen control in your layout, you can delete it from the
workspace.
Delete a screen control
1. In MainStage, select the screen control you want to delete.
2. Choose Edit > Delete (or press the Delete key).
When you delete a screen control, any assignments or mappings for the screen control are
deleted as well.
Assign hardware controls to screencontrols
Overview of controller assignments in MainStage
To use MainStage with a MIDI controller, you assign hardware controls on the controller
(such as faders, knobs, buttons, drum pads, and pedals) to screen controls such as knobs
and buttons in the workspace. After you assign a hardware control to a screen control,
the screen control receives the MIDI messages from the hardware control. You only need
to make controller assignments once for a concert as long as you use it with the same
hardware.
You assign hardware controls to screen controls using the Learn process, which is
described in Learn a controller assignment in MainStage. You can also assign hardware
controls in the Assignments & Mappings table. For information, see Overview of
assignments and mappings in MainStage.
When you assign a hardware control using the Assign button, MainStage determines
the type of MIDI message the control sends when you move it and the range of values
the control is capable of sending. When you map the screen control to a channel strip
parameter or an action, MainStage converts (or “maps”) the range of values sent by the
hardware control to the optimal range of values usable by the parameter.
For example, many faders, knobs, and other MIDI controls send a range of numeric values
between 0 and 127. You could map a hardware knob with this range of values to control the
frequency parameter of an EQeffect, which has a range of usable values between 20Hz
and 20kHz. When you map the screen control for the knob to the EQfrequency parameter,
MainStage converts the values sent by the hardware knob to be distributed between the
minimum (20Hz) and maximum (20kHz) values for the parameter.
Knob assignments in MainStage
MIDI controllers can have different types of knobs or rotary controllers. Knobs can be
either absolute controllers, which send a fixed value determined by the knob’s position or
can be relative controllers, which increment or decrement the previous value regardless
of their exact position. Knobs can either have a fixed range of movement or be continuous
(sometimes called endless rotary encoders).
