Compatibility determination apparatus and method can properly determine compatibility between elements in an electronic music apparatus. When a reproducing program holds version information indicating, for example, that the own version of the program is 4.0 and music contents of versions 1.0 and 2.0 are reproducible by the program, and a music content holds version information indicating, for example, that the own version of the music content is 3.0 and programs of versions 4.0 and 5.0 can be reproduced on the music content side, the program of version 4.0 can be reproduced on the music content side. Although the information held in the program side does not indicate that a music content of version 3.0 is reproducible by the program, the music content of version 3.0 can be reproduced by the program of version 4.0. Thus, the apparatus and method can properly determine compatibility between the elements.

Detection outputs value based on outputs of a sensor for detecting a depressed position of a pedal are input via the input section; meanwhile, a detection output value corresponding to a non-depressed state of the pedal is set as an offset value. The detection output value, input via the input section, is adjusted with the offset value, so as to provide an adjusted detection output value corresponding to an actual depressed amount of the pedal. The adjusted detection output value is converted into a control value corresponding to the depressed amount of the pedal. Thus, the offset value is variably set in accordance with an individual difference, aging, etc. of the pedal, so that the detection output value adjusted with such an offset value can be a value having unevenness in the sensor outputs, which may have occurred due to an individual difference, aging, etc. of the pedal, automatically compensated.

To a tone generation apparatus is removably attachable a plug-in board for generating a tone on the basis of performance information and extending the tone generating function of the tone generation apparatus. Tone color name information and tone color parameter name information of tone color data possessed by the attached plug-in board is stored in a nonvolatile memory. Thus, any tone color possessed by the plug-in board can be known with reference only to the nonvolatile memory and without a need to refer to the plug-in board. The nonvolatile memory can also store tone color data of a custom voice obtained by editing original tone color data of the plug-in board. With this arrangement, the plug-in board is allowed to obtain the tone color data of the custom voice from the nonvolatile memory, as necessary.

An electronic musical instrument is equipped with manual operators such as switches and controls arranged on an operation panel and keys of a keyboard as well as a display and a tone generator. It is characterized by automatically running demonstration programs when it is supplied with electric power but is left unattended at a store or in an exhibition area. The demonstration programs are started after a lapse of a predetermined time or more under prescribed conditions where none of the manual operators is operated by a user, no tone-generation instruction is issued with respect to automatic performance being played by internal functions, and no tone-generation instruction is issued with respect to external performance data being supplied by means of a communication interface. Under each of those conditions, the electronic musical instrument automatically runs a display demonstration program for displaying preset images on a screen of the display and/or a sound demonstration program for generating preset sounds. Specifically, the display automatically shows specifications, system configurations and messages with regard to the electronic musical instrument. In addition, the tone generator automatically generates automatic performance sounds or vocalized sounds of voice guidance to overall operation of the electronic musical instrument. Thus, it is possible to attract interests of visitors and customers at stores or exhibition areas.

A musical tone synthesizing apparatus utilizes digital signal processors (DSPs) to realize synthesis of musical-tone waveforms with regard to a variety of tone colors. The apparatus stores microprograms and tone-color parameters in advance. Herein, the microprograms represent musical-tone-synthesis algorithms each synthesizing musical tones of a specific tone color. The tone-color parameters contain common parameters and selective parameters to provide a compatibility between different systems having different scales in hardware and software. The common parameters are commonly shared by the different systems, while the selective parameters are provided for a selective use of the musical-tone-synthesis algorithms. So, the apparatus responds to a selection of the musical-tone-synthesis algorithms, wherein the apparatus executes the selected musical-tone-synthesis algorithm, using the common parameters and at least one of the selective parameters, to synthesize musical-tone waveforms with regard to a desired tone color. Incidentally, it is possible to provide different algorithms with regard to derivative tone colors which derive from a base tone color.

Musical tone synthesizing apparatus having competibility of tone color

A musical tone synthesizing apparatus is used to synthesize musical-tone waveforms on the basis of simulation of a tone-generation mechanism of a musical instrument. Herein, a drive signal is generated based on an excitation envelope signal in accordance with a manipulation of performance made by a human operator (e.g., performer) and is then converted to an excitation signal in accordance with an operating behavior of the musical instrument. For example, the operating behavior indicates a behavior of a reed portion of a wind instrument to which breath is blown in; or it indicates a behavior of a string of a stringed instrument which is striken or plucked. The excitation signal is input to a physical-model sound source realizing resonating-body/vibrating-body models. The physical-model sound source performs calculations, simulating the tone-generation mechanism of the musical instrument, on the excitation signal to produce a musical tone signal. An amplitude envelope signal as well as an effect are imparted to the musical tone signal, thus providing a synthesized musical tone output. The excitation envelope signal and amplitude envelope signal are controlled in level in a variety of ways in response to an instruction to generate a next note during generation of a current note. For example, formation of an attack portion is started to follow a current level of the excitation envelope signal, whilst the amplitude envelope signal is damped in level to a damp level, then, formation of an attack portion is started to follow the damp level of the amplitude envelope signal. Thanks to the controlling of the envelope signals, it is possible to realize special techniques of performance such as one-note-by-one-note crescendo without causing delay in generation of notes.
