User Interface Basics

OB-Xf is seperated in different sections:

Surge XT parameters display as number fields, value fields, buttons, or knobs.

Knob movement:

  • Left mouse button and drag vertically rotates the knob
  • Shift + Left mouse button and drag vertically moves the knob with fine control
  • Scroll Wheel moves the knob in steps
  • Shift + Scroll Wheel moves the slider in small steps

Other slider actions:

  • If you have Alt pressed when you release a left-drag, the slider snaps back to its initial position
  • Double Left-click resets the parameter to its default value
  • Right-click displays the context menu
  • Hover displays its value

Right-click on a knob to display its context menu.

For help with a parameter, select the ? option, or hover the parameter and press F1.

A text field with the highlighted current value is displayed, and a new value can be typed in. There is no need to enter the unit of the entered value. Press Enter to commit the change. To exit without committing the change, press Escape or focus elsewhere.

If you use the CLAP or VST3 version of Surge XT, and depending on your host, options from your host may display in this sub-menu. These can be related to automation, MIDI, or parameter values.
