• e) selection means for:
• i) allocating the performance data output from said performance data generating means to multiple groups on the basis of a predetermined standard when the mode indicated by said mode indicating means is said first mode, and supplying the performance data allocated to a respective group is then supplied to at least one respective corresponding musical tone generating system, the correspondence between groups and musical tone generating system having been determined on a predetermined basis,
• ii) allocating the performance data output from said performance data generating means to each of said multiple musical tone generating systems when the mode indicated by said mode indicating means is said second mode;
• f) distribution means for:
• i) supplying to each musical sound producing system the musical tone signals output from all of the musical tone generating systems when the mode indicated by the mode indicating means is said first mode,
• ii) supplying to each musical sound producing system the musical tone signal output from a corresponding musical tone generating system when the mode indicated by said mode indicating means is said second mode, such that each musical tone signal is supplied to a different musical sound producing system.

An electronic musical instrument comprising:

• a) performance date generating means for outputting performance data which corresponds to a musical performance;
• b) tone data memory means for storing tone data representing a plurality of waveforms corresponding to musical tones;
• c) multiple musical tone signal generating systems for producing musical tone signals in response to said tone data and said performance data;
• d) mode indicating means for indicating:
• i) a first mode wherein musical sound is generated in response to musical tone data representing a waveform which corresponds to one musical tone,
• ii) a second mode wherein musical sound is generated in response to musical tone data representing waveforms which corresponds to at least two musical tones,
• e) allocation means for allocating said performance data output from said performance data generating means to each musical tone signal generating system, said allocating means allocating a single musical tone datum among said tone data to each musical tone signal generating system when the mode indicated by said mode indicating means is said first mode, said allocating means allocating a different musical tone datum among said tone data to each musical tone signal generating system when the mode indicated by said mode indicating means is said second mode.

An electronic musical instrument comprising:

• a) a plurality of musical tone signal generating means, each of which generates a musical tone signal;
• b) a plurality of sound producing means, each of which produces musical sound in response to said musical tone signal;
• c) mode selecting means for selecting one of a first mode and a second mode;
• d) selecting means for selecting one of said plurality of tone signal generating means when said first mode is selected, wherein at least one of said plurality of sound producing means produces a musical tone in response to a musical tone signal generated by said musical tone signal generating means selected by said selecting means;
• and
• e) distributing means for distributing musical tone signals generated by said plurality of musical tone signal generating means to respective sound producing means of said plurality of sound producing means when said second mode is selected.

An electronic musical instrument comprising:

• a) memory means for storing waveform data including a plurality of waveform data components;
• b) a plurality of musical tone signal generating means, each of which generates a musical tone signal in response to a waveform data component from said waveform data;
• c) mode selecting means for selecting a first operating mode or a second operating mode;
• and
• d) assigning means for assigning waveform data, wherein said assigning means assigns a waveform data component from among said waveform data to at least one of said plurality of musical tone signal generation means when said first mode is selected, and assigns at least two waveform data components from said waveform data to respective musical tone signal generating means when said second mode is selected.

An electronic musical instrument comprising:

• a) a plurality of musical tone signal generators, each of which generates at least one musical tone signal;
• b) a plurality of sound producing devices, each of which produces musical sound in response to a musical tone signal generated by said musical tone signal generators;
• c) mode selection means for selecting one of a first mode and a second mode;
• d) signal generator selecting means for selecting only one of said plurality of musical tone signal generators when said first mode is selected, wherein at least one of said plurality of sound producing devices produces a musical tone in response to a musical tone signal generated by said selected musical tone signal generator;
• and
• e) distributing means for distributing at least two different musical tone signals generated by said plurality of musical tone signal generators to at least two respective sound producing devices of said plurality of sound producing devices when said second mode is selected.

An electronic musical instrument comprising:

• first generating means for generating a first musical tone signal;
• second generating means for generating a second musical tone signal different from said first musical tone signal;
• first producing means for producing a musical sound in response to a musical tone signal inputted thereto;
• second producing means for producing a musical sound in response to a musical tone signal inputted thereto;
• mode selecting means for selecting a first mode or a second mode from among a plurality of modes;
• and
• assigning means,
• (1) when said first mode is selected, for assigning said first musical tone signal to at least one of said first producing means and said second producing means, said first producing means producing a first musical sound in response to said first musical tone signal if said first musical tone signal is assigned thereto and said second producing means producing a second musical sound in response to said first musical tone signal if said first musical tone signal is assigned thereto, and
• (2) when said second mode is selected, for assigning said first musical tone signal to said fist producing means, said first producing means producing said first sound in response to said first musical tone signal, and for assigning said second musical tone signal to said second producing means, said second producing means producing a second sound in response to said second musical tone signal.
