Using the Knob
Turning the knob modifies the currently focused control. If the control is a unit entry control, the knob
increments and decrements its value with an appropriate resolution. If the control is a drop-down list the
knob cycles through the entries in the list. Three different knob acceleration profiles can be selected
from the
preferences panel . A control can be selected as "Sticky" in which case the knob will continue
to control it even though focus is given to another control. When cursors on a graph are active the knob
controls the active cursor position.
Using the Virtual Keyboard
For situations where it's necessary to enter text into a control and an external keyboard is not available
the Virtual Keyboard can be selected from the
SR1 keypad or from the Tools Menu . The virtual keyboard
offers the full functionality of a standard PC keyboard but can be operated with just a mouse or the
trackpad.
