Benefits of technology

According to the invention, when a specific timbre is designated by the admitted designation information and when a musical sound can also be produced by a tone generator of the superior sound producing system, the designation information is suitably rewritten so as to activate the superior sound producing system even if the inferior sound producing system is designated, whereby a sound in a higher-qua

Problems solved by technology

However, it is unnatural for the electronic musical instrument not to produce a sound while receiving a tone generation command to request sound production.
Thus, the sound source of the physical model system is not good for preparing a wide variety of timbres.

Embodiment Construction

FIG. 1 is a block diagram of an electronic musical instrument according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a microcomputer (CPU) which exercises various kinds of control over the electronic musical instrument by executing programs stored in a ROM 2. The ROM (Read Only Memory) 2 stores programs to be executed by the CPU 1 and preset voice data to be reproduced. A RAM (Random Access Memory) 3 is used as a working area or the like for the CPU 1 to execute the programs. A MIDI interface 4 is provided for sending a MIDI message created within the electronic musical instrument to the outside and for receiving a MIDI message from the outside. A tone generator 5 is composed of a waveform memory type synthesizing circuit having a waveform memory in which plural musical sound waveforms are stored to create a wide variety of timbres. Another tone generator 6 of the physical model system is constructed to stimulate physical behavior of a natural mu...

Abstract

An electronic musical instrument has a composite sound source for generating a musical tone, and includes a first synthesizing circuit for creating a variety of timbres of the musical tone having a superior quality and a second synthesizing circuit for creating another variety of timbres of the musical tone having an inferior quality. The instrument admits designation information effective to designate one of the first and second synthesizing circuits to be activated and effective to designate a timbre to be created by the designated one of the first and second synthesizing circuits. A detector operates when the second synthesizing circuit is designated for providing a detection signal if the designated timbre can be also created by the first synthesizing circuit. A controller responds to the detection signal for altering the admitted designation information so that the first synthesizing circuit is activated in place of the second synthesizing circuit so as to create the designated timbre by the superior quality.

Description

BACKGROUND OF THE INVENTIONThe present invention relates to an electronic musical instrument having a plurality of musical sound synthesizing circuits which have different tone generation mechanisms.Conventionally, the electronic musical instrument has musical sound synthesizing means which produces a musical sound in a timbre specified by timbre designation information. The timbre designation information is externally supplied to the electronic musical instrument to create a timbre for a produced musical sound.One type of the electronic musical instrument has a wide variety of available timbres. Another type of the electronic musical instrument has only a small number of available timbres. When an electronic musical instrument having only a small number of timbres is supplied with timbre designation information which specifies a timbre not available by the instrument, it cannot produce a sound by the specified timbre. However, it is unnatural for the electronic musical instrument n...
