Control Types
Section titled “Control Types”OB-Xf parameters can be controlled with knobs, toggle buttons, multi-state buttons, menus and text entries.
- Left click and dragging vertically moves the knob.
- Holding Shift while dragging vertically moves the knob with much higher precision.
- Mousewheel moves the knob in steps.
- Holding Shift while operating the mousewheel moves the slider in small steps.
- For knobs pertaining to pitch adjustment, holding Alt (⌥ on macOS) will jump in predefined intervals (4th, 5th, octave, and their multiples).
- Hovering above the knob will uncover a popup showing the parameter’s value.
- Double-click resets the parameter to its default value.
- Right-click displays the parameter’s context menu
Knob Context Menu
Section titled “Knob Context Menu”The knob context menu provides the full name of the parameter, a text entry field displaying the parameter value (which is also automatically selected and awaiting text input), and and option to reset the parameter to its default value.
Pan knobs in Voice Variation section provide additional options. More about that in Voice Variation section.
Certain hosts can provide additional context menu options for VST3 and CLAP formats, which would show here. These options are usually related to parameter automation, MIDI learn, and so on.
Toggle and Multi-state Buttons
Section titled “Toggle and Multi-state Buttons”These controls are as straightforward as they can be. Left click will change their value, the only difference is that multi-state buttons have more states than just on and off. They are signified either by existence of two LEDs on them, or by rotating through multiple colors, as showcased below.
These controls provide multiple options through a context menu, and are stylized to look like 14-segment LCDs for that ultimate vintage synthesizer vibe.
Simply click on the LCD and the options will show!
Text Entry
Section titled “Text Entry”These controls allow you to input text, which is crucial for specifying important patch information like name, author and license.
