There are a few universal actions that apply to the whole of OB-1.
To turn a knob, click and drag your cursor up or down. For continuous knobs, you can also use a scroll wheel or gesture whilst hovering over the knob you wish to change.
Hold down the shift key whilst moving a knob to access finer resolution control.
As you adjust a continuous parameter on OB-1 the value for that parameter will be shown on a floating “tooltip” window below and to the right of the knob.
Click the knob to show the current parameter value without changing it.
You can click in the tooltip window to manually type in a desired parameter value.
The tool tip will remain visible for the length of time specified in the Settings Window after releasing the knob.
OB-1 has some features selected via menu windows. There are two types.
Firstly, windows with up and down arrows on the right hand side, for example, the aftertouch and velocity destinations.
A single click in the lower half of window will move the option on one place. A single click in the upper half will move the option on one space.
Right-clicking the window will provide a menu of options to choose from, useful for those who know what they want.
Secondly there are windows with no arrows, such as polyphony and note selection in the sequencer. These windows need to be click and dragged to set their value.
The Scale window is a hybrid of the two, it’s draggable and right-clickable.
