The stock Slider Control in Synthedit has one major disadvantage- It’s not resizable. This project uses third party modules, and can be re-sized by editing its panel view. Note: Resizing the actual slider knob does mean creating a new .png file for it. This control also has the option to “spring” back to a default value, which can be useful, you could use it as a pitch bend slider control for example.
The Joystick/Slider module.
The ED Joystick Image control is used for the slider control itself, there are few properties settings to note, see below:
Setting Constrain X Max to 0 stops any horizontal movement of the control by locking it to the 0 position. Leave the Constrain Y settings as Min=0 and Max=1 as we want the full range.
Ctrl Scaling factor sets how fine the control movement is when holding the Ctrl key down and moving the slider. Both the backgrounds are set as 00 for the Alpha (transparency) level so the rest of the ARGB setting can be left blank.
The Mouse Down plugs are connected so that the control will be returned to it’s default position when this option is selected.
The control background and scale grid.
The background for the control is supplied by another third party control, the DAM Rectangle, which allows us a resizable background, outline and grid with control over the colours of the background and grid, the settings are shown below.
Although I have left the background colour as preset, you could easily link the Top ARGB and Bottom ARGB to allow these as user settings.
The “Spring”.
This is the section that allows us to have a position that the control automatically returns to our user determined default position as soon as the left mouse button is released. Although we have two Spring modules connected only one needs a Reset and normalized value set ( the Y position) Note: Although it seems like only one Spring module is needed this will not work without both connected as shown.
The reset value is the position we want the control to return to, and it is the normal GUI float range of 0 to 1, so to return to the mid position a value of 0.5 must be set for the “Spring Position”. This is independent of any values given to the Min Max values for the control, and will always follow this 0 to 1 scale.
The label and value display.
Another third party module is in use here, the DAM Text Enter module as this gives us greater control over the text formatting than the stock SE text modules.
Float to text is used to for the value readout with an ED GUI Multiply (Float) so re can re-scale the readout ( for example you want to convert a range of 0 to 10 to a range of 0 to 100%- this only affects the display, not the Volts/Float outputs.
Output.
I have Included a GUI Float output, a DSP Float output, and a Volts output. The Float to Volts conversion is set to smooth (30mS).
Resizing the control.
All that need to be done is open the Panel View then drag the relevant controls to their required sizes, then lock and close the panel view.
The panel view and control settings are shown below.
