To access the Num-Pad:
Num-Pad is designed to set channel levels with a touch screen or with a mouse. For the most part it replicates the numeric keypad on the keyboard.
For further details about selecting a channel, see Channel space
The selection set created in the Num-Pad appears in the feedback area of the screen.

Certain midi devices have numeric keys that send midi, such as the Evolution UC-33.

NumPad is completely assignable in midi.
See Midi Configuration and Midi Assignment.
This wheel is specially created for midi devices, especially those with rotary encoders, like on a BCF or a UC-33.
This wheel sets the channel levels for selected channels both in stage and in Blind.
It has two modes:
To select which mode the wheel is to be set to is done by clicking the wheel mode box, which toggles between [A] and [R].
Eventually you will be able to use this wheel with the mouse, but only in Absolute mode.
A slider, or a rotary knob has by default a start point, and an end point: minimum and maximum. In midi, 0 and 127. This limitation is physical for absolute controls.
If your midi device has fixed stop sliders or rotaries, you can only work in Absolute mode.
Channels selected will receive the level of the midi controller converted to a percent.
This level will replace the previous level of the channel(s).
Manually set a channel at 70% and by slightly touching your control you will transfer its level directly to the channel.
Here the channels are set at 92/100 (118/127 converted to a percent):
Certain devices have these endless controls.
They deliver a signal that can be set inside of the midi device
This happens instantly without fading.
To program a BCF2000 rotary in Relative mode ( manipulations inside the Behringer device ) :
In White Cat, set the level wheel to relative mode:
Each channel selected will decrease or increase from one step, receiving the relative pulse. Relative mode produces the same effect as using the [UP] and [DOWN] arrow keys
Selecting a channel and setting it at 11% and then moving the rotary to the left will decrease the selected channels in 1% increments:
To assign a midi signal to the level wheel:
This small circle enables you to send the level of the wheel to the Midi Out port.
