Graphical user interface (GUI), a synthesiser and a computer system including a GUI
The present invention relates to a graphical user interface (GUI), a synthesizer and a computer system including such a graphical user interface. In the prior art, input signals may be modified using a variety of controls including rotatable knobs or levers or switches or effected via software controls. Hitherto, the value of each signal has been represented in a dedicated manner even when signals are being combined and this adds to the complexity for a user. The present invention thus relates to a graphical user interface for displaying three or more input signals; comprising a geometric display having the number of dimensions equal to one less than the number of signals whereby each signal represents an apex of the geometric display and a cursor is disposed within the geometric display and represents the combination of the signals.
