Electronic stringed instrument

DETAILED DESCRIPTION The present invention has been developed to overcome the above conventional problems, and it is therefore an object of this invention to provide an electronic stringed instrument, which expands the limited function of conventional picking signal input devices so that the output of the same picking signal input device can also be used for other purposes, particularly, for selection of other tone parameters, and which prevents deterioration of the operability due to the functional expansion.
It is another object of this invention to provide an electronic stringed instrument which eliminates the need for providing a number of musical tone parameter select switches on a narrow instrument main body to select a desired musical tone parameter and needs a simple picking signal input operation to quickly and easily select the desired musical tone parameter.
It is a still another object of this invention to provide an electronic stringed instrument in which, in selecting a musical tone parameter, when a plurality of strings are erroneously triggered simultaneously by the picking operation or when the picking of strings is performed with an open-string operational status, it is possible to assuredly prevent an unintended musical tone parameter from being set.
Development and Operation of the Invention The mode selecting section used in this invention can be designed so as to be able to select a desired mode not only from two modes but also from among three or more modes.
This feature can be realized by the use of a mechanical rotary switch or a rotary switch (structurally, a two-position switch) which electronically advances the mode.
According to one arrangement, a timbre select mode can be set by the mode selecting section.
In the timbre select mode, a picking signal, such as a pitch designation signal or a string vibration period signal, is given from the picking signal input device.
Musical tone parameter setting means selects one of plural pieces of timbre data based on the received picking signal
