Control Change commands with increasing or decreasing values are sent when you rotate the dial. Select the CC number and channel (1-16) to use, the min and max values (0-127) to be sent when the dial is rotated.

NRPN commands are configured the same way as CC commands, with the difference that both the controller and the value range from 0-16.383.

Control Change commands with static values are sent when you rotate the dial, and different commands can be sent on clockwise and counterclockwise rotations. For each physical step of the dial, the same command is sent. This is used for functions where the command signal steps in a direction rather than an absolute value. When Control Change (CW/CCW) is selected, the dial is endless.

The Pitch Bend, Aftertouch, and Program Change commands have no "Control" field since they don't have any value associated with them. Contrary to the CC/NRPN commands, where you have a fixed control for which the dial controls the values sent, the dial for these commands affects the "control" itself, i.e., the Pitch Bend, Aftertouch, or Program.

The value range for Pitch Bend is 0-16,383, while Aftertouch and Program Change range from 0-127.

You can choose from a built-in set of fader designs or add your own design. Please check the page for dial fader image files for more details on custom faders.

You can enter a title that will be displayed superimposed over the fader, and you can set the text and background colors to make the title visible against the fader background. The title can reference the LCD strip information for the channel by using the tags #LCDU# and #LCDL# for the upper and lower LCD strip rows. The Mackie channel number can be referenced using the tag #CHNR#. This is the sequential number counting from the first channel on the first Mackie Control device to the last channel on the last Mackie Control device.

A value can be displayed above the fader, and you can show the raw Midi value, a percentage (0 to 100% or -50- to 50%), a preconfigured pan value, a value from a translation file or a dB value. Some built-in dB files are available, and you can add your own dB configuration as described on the Fader DB Files page. You can set the text color for the value but no background color.

Since the fader and the title occupy the same space, you can select what will happen when the fader handle and the title "collide".

• If you select to move the title, it will be located on the left side of the fader when the handle is on the right half, and vice-versa.
• If you select to hide the title, it will be located on the left side of the fader when the handle is on the right half and hidden when the handle is on the left half.
• If you select to do nothing, it will be stationary on the left side of the fader, even when the handle occupies the same space.

You can choose from a built-in set of V-pot designs or add your own design. Please check the page for V-pot image files V2 for more details on custom faders.

The value display options are the same as described for the fader above, and you can set the text color. The value is displayed outside the V-pot. You can enter a title that will be displayed superimposed over the center of the V-pot and set the text color to make the title visible against the V-Pot.

You can choose to display the V-pot in half or full size.

The V-pot state can be displayed with a ring around the centerpiece. A portion of the ring will be displayed according to the selected option:

• If the active span indication is From min to max (volume), the ring will be visible from the leftmost position (= midi value 0) to the current midi value.

• If the active span indication is From midpoint (pan), the ring will be visible from the center position (= midi value 64) to the current midi value (left or right).

• If the active span indication is From midpoint (spread), the ring will be visible from the center position (= midi value 0) to both sides with a total span at midi value 127.

• If the active span indication is At current value, the ring will be visible only at the current midi value.

• If the active span indication is None, the ring will not be visible.

You can show the raw Midi value, a percentage (0 to 100% or -50- to 50%) or a dB value for text display. Some built-in dB files are available, and you can add your own dB configuration as described on the Fader DB Files page.

You can select to send the same commands as when rotated, send a different command when you rotate the dial while pressed or have no action.

If you select "Same as above", the only available property is the step size. This configuration is targeted at giving the rotation action coarse control with larger steps and the rotation while pressed fine control with smaller steps.

You can select not to have any graphical display for this action or choose between two bar types. In the picture, the upper one is the "pan" bar, where a triangle marks the current value (pan position). The lower bar is the "volume" bar filled from the left to indicate the current value.

For text display, you can show the raw Midi value, a percentage (0 to 100% or -50- to 50%), a preconfigured pan value, a value from a translation file or a dB value. Some built-in dB files are available, and you can add your own dB configuration as described on the Fader dB Files page.

When the dial is pressed, you can send Control Change, Note On/Off, Program Change, Pitch Bend, and Aftertouch commands. The additional options depend on which command type you select.

If the action is placed in a stack, the action will never be triggered by a dial press.

The Press action is not associated with any icon in the display, but the left and right screen tap actions can be configured to use the Press command, and their icons will then be associated with the Press command.

Select the Control, Key or Program you want to control with a dial press, and select the Midi channel.

Control Change and Note actions can be defined as Push or Toggle actions. A Push action will always send the On value when the dial is pressed. A Toggle action alternates between the On and Off values when the dial is pressed. Note actions will send a Note On command when sending the On value and a Note Off command when sending the Off value.

Set the values that should be sent for On and Off for the command.

The checkbox determines how received values affect the action state:

• If the checkbox is checked, all received values on and above the defined On value will set the action in the On state; values below the On value will set the action in the Off state.

• If the checkbox is cleared, the action is set in the On state only when the exact defined On value is received; all other values will set the action in the Off state.

Apart from the common parameters explained above, there are no additional options when selecting Pitch Bend, Aftertouch or Program Change. These commands have no additional parameters; either you send a Pitch Bend, Aftertouch or Program Change command, or you do not. You cannot set these commands On or Off, so when Pitch Bend, Aftertouch or Program Change is selected, a screen tap is, by definition, a Push action, and the same command will be sent every time.

The left and right screen tap actions work precisely as the dial press action; you can send Control Change, Note On/Off, Program Change, Pitch Bend, and Aftertouch commands when the left or right half of the screen is tapped. Additional options depend on which command type you select.

Screen tap actions can also be configured to use the Press command instead of being individually configured. When doing so, the screen tap action will send the Press command, and the associated icons will display the state for the Press command.

You can enable state icons showing the selected command's current state in the top left and right corners of the dial's display. Select the icons/images displayed for the On and Off states. Images can be of any size; they will be resized to fit in the space (40x40px or 90x90 if large icons are selected). The selected icon is displayed on the button.

Clicking on one of the Select buttons will open a file browse dialog where you navigate and select the image you want. If you want to use icons from the icon library, you need to navigate to where the image files for the icon library are located.

• Windows: "%appdata%\Elgato\StreamDeck\IconPacks"

• macOS: "~/Library/Application Support/com.elgato.StreamDeck/IconPacks"

If you have selected to show large icons in the dial press configuration, the icons will fill the entire screen space (for the dial), and the fader/V-pot/bar display for rotate actions is only visible while the dial is rotated.

The "Show large icons" checkbox is available in both the left and right screen tap sections, but it is the same property, so it doesn't matter which one you use.

Select the Control, Key or Program you want to control with a dial press, and select the Midi channel.

Control Change and Note actions can be defined as Push or Toggle actions. A Push action will always send the On value when the scfreen is tapped. A Toggle action alternates between the On and Off values when the screen is tapped. Note actions will send a Note On command when sending the On value and a Note Off command when sending the Off value.

Set the values that should be sent for On and Off for the command.

The checkbox determines how received values affect the action state:

• If the checkbox is checked, all received values on and above the defined On value will set the action in the On state; values below the On value will set the action in the Off state.

• If the checkbox is cleared, the action is set in the On state only when the exact defined On value is received; all other values will set the action in the Off state.

Apart from the common parameters explained above, there are no additional options when selecting Pitch Bend, Aftertouch or Program Change. These commands have no additional parameters; either you send a Pitch Bend, Aftertouch or Program Change command, or you do not. You cannot set these commands On or Off, so when Pitch Bend, Aftertouch or Program Change is selected, a screen tap is, by definition, a Push action, and the same command will be sent every time.

VU display

The VU meter can be displayed integrated into the fader view, as with the Generic Midi button, or full screen.

Commands

MIDI commands, control, and channel properties work the same way as for the rotate action. Please see the property descriptions in that section.

VU Scale (integrated)

The VU scale in the integrated view uses the same VU Scale functions as the other buttons and dials that display integrated VU.

VU Scale (full screen)

The VU scale maps incoming MIDI values to the needle's position on the VU display. The simplest scale is the linear scale, which maps the value 0 to the leftmost edge and 127 to the rightmost edge, with a linear progression between the edges. If that or any of the other built-in scales doesn't match the VU source you are connecting to, you can use the VU calibration window to create your own scale.

VU Design (full screen)

You can choose from a built-in set of VU designs or add your own design. Please check the page for dial VU image files for more details on custom VU designs. If the selected design has a frame image defined, you can choose whether to display it.

Smoothing (full screen)

Without smoothing enabled, the VU needle will respond to every VU value that is received. This will provide a fast and accurate response, but it can be a bit frantic.
With smoothing enabled, the plugin will calculate a running average over the specified time period. This will give a more stable appearance, but with a slower response to changes. The longer the time period you select, the more stable and slower to respond the VU meter will be. The default value of 300ms is said to be a good approximation of a physical VU meter's inertia.

Peak Hold (full screen)

With peak hold selected, a shadow needle will indicate the peak level for the defined time period. 

Rotate behavior (full screen)

I think a common way to configure a dial with a VU meter is to have the rotate action control a track's volume while the VU meter displays the VU levels for that same track. In such a configuration, it is somewhat counterproductive to remove the VU meter from the screen to make room for the volume fader, since you probably want to see the VU level response to the volume change you make. With this dropdown, you can control the behavior when rotating the dial and, if desired, keep the VU meter on the display, optionally complemented by a volume-level overlay.

VU calibration is the process of teaching the plugin to map incoming MIDI commands to the VU scale in the display. The principle is quite simple: feed the plugin a steady signal, then save the MIDI value for each numbered level on the VU meter.

The best signal to use is pink noise, but any steady signal, such as a sine wave, can be used.

For each numbered level (-20, -10, -7, etc.), adjust the volume until the needle reaches that level, then press the "Set level" button in the calibration window.

You don't need to set every level; the plugin will interpolate values between the assigned levels. Set at least the -20, 0, and 3 levels to achieve a reasonable response from the VU meter. The more levels you configure, the more accurately the output will match.

If you cannot, for some reason, produce a steady signal to calibrate the VU meter, you can manually enter MIDI values in the fields for each VU level.

If you started with a built-in VU Curve, you need to save your new calibration as a custom file; you cannot overwrite the built-in VU Curve file. All custom files are stored in the "Documents/Trevliga Spel/VUCurves" folder; if the VUCurves folder does not exist, it is created.

When saving the calibration, you can set the name to be displayed in the dropdown, as well as the file name.
