Abstract:
1. A method for operating a musical instrument tuner, the tuner comprising an input module, a signal analyzer, a display, and a housing; the input module, the signal analyzer and the display forming a part of said housing or being comprised in said housing; the input module receiving an input signal from a musical instrument; the display enabling at least two display modes from a group of display modes, the display modes comprising a monophonic display mode and a polyphonic display mode; the method comprising the steps of initiating a user session mode; automatically determining a user session mode and shifting the user session mode from one of the previously selected user session modes to the automatically determined user session mode; when the user session mode is selected to be the polyphonic mode, determining a polyphonic characteristic of the input signal, the polyphonic characteristic including representations of multiple pitch frequencies derived from said input signal, and displaying said polyphonic characteristic in a polyphonic display mode on said display, when the user session mode is selected to be the monophonic mode, determining a monophonic characteristic of the input signal, the monophonic characteristic including a representation of a pitch frequency derived from said input signal, and displaying said monophonic characteristic in a monophonic display mode on said display; determining a signal class of the input signal by means of a signal classifier, the signal class being from a group of classes at least comprising and basing the step of automatically determining a user session mode on said determined signal class.
