Electronic musical instrument having channel controller preferentially assigning sound generating channels to resonant sound signals with large magnitude

An electronic musical instrument capable of concurrently producing more than one electronic sound, comprising:

• a plurality of tone specifying means manipulated by a player for specifying a note of a fundamental sound to be produced, said player being able to manipulate more than one tone specifying means so as to specify more than one fundamental sound to be concurrently produced;
• at least one musical effect applying means manipulated by said player for imparting a music effect to said fundamental sound or said more than one fundamental sound;
• and
• a tone generating means for producing said fundamental sound or said more than one fundamental sound without a manipulation of said at least one musical effect applying means, and imparting said music effect to said fundamental sound or said more than one fundamental sound under the manipulation of said at least one music effect modifying means, said tone generating means including
• a plurality of sound generating channels selectively assigned to a fundamental sound signal representative of said fundamental sound or fundamental sound signals representative of said more than one fundamental sound, said plurality of sound generating channels being further assigned to a sound modifying signal associated with said fundamental sound signal for imparting said musical effect to said fundamental sound or sound modifying signals respectively associated with said more than one fundamental sound signal for imparting said music effect to said more than one fundamental sound;
• a signal generating means responsive to said plurality of tone specifying means and said at least one musical effect applying means for producing said fundamental sound signal, said fundamental sound signals, the combination of said fundamental sound signal and said sound modifying signal or the combination of said fundamental sound signals and said sound modifying signals, and
• a channel controlling means checking said sound generating channels to see whether or not the sound generating channels assigned to said sound modifying signals exceed a predetermined number equal to or less than the maximum number of sound generating channels assignable to said fundamental sound signals, said channel controlling means restricting the total number of sound generating channels assigned to said sound modifying signals equal to or less than said predetermined number.
