Local control function apparatus having a single switch
First Claim
1. An electronic musical instrument, which, depending upon the state of a local control function, plays music independently or in conjunction with an external device that is in electrical communication with said electronic musical instrument, said electronic musical instrument having a power switch having an "on" and an "off" state, comprising:
- a plurality of operational terminals, each operational terminal of said plurality of operational terminals having an "on" state and an "off" state;
a predetermined operational terminal of said plurality of operational terminals being designated as a local control function switch;
detecting means for detecting depression of said predetermined operational terminal immediately after said power switch is placed in its "on" position;
said detecting means including scanning means for scanning said plurality of operational terminals;
an event map means for providing data to said detecting means concerning a prior setting of said predetermined operational terminal;
initial setup means for setting an initial state of said local control function in accordance with data acquired by said detecting means;
the local control function of said electronic musical instrument being placed into its previous setting immediately after power switch-on if the event map means indicates that there has been no change in the position of the predetermined operational terminal from a previous position thereof; and
said local control function being changed from its previous position immediately after power switch-on if the event map indicates that a change has occurred in the position of the predetermined operational terminal relative to a previous position thereof.

Abstract
An electronic musical instrument, which, in consonance with the state of a local control function, is designed to play music independently or in conjunction with an external device, includes a detector for detecting a depression of a predetermined operation terminal immediately after power switch-on. It further includes an initial setup device for setting the initial state of the local control function in accordance with the data acquired by the detector.
