Abstract
Abstract A performance apparatus for producing a mixed musical tone signal having a comparator and a modulator. The comparator detects key data corresponding to musical tones having the same pitch and the same or similar tone colors from key data of musical tones to be mixed. The modulator changes at least a tone element of the mixed musical tone signal on the basis of the key data detected by the comparator to produce tones having multiple-tone like tone colors. The modulator comprises a detuner for detuning pitches of some musical tones of a plurality of musical tones formed based on the key data detected by the comparator, or comprises a modulator for modulating an amplitude or a frequency of the musical tone signal formed and mixed bases on the key data detected by the comparator.

Independent Claim
111 words
A performance apparatus comprising: a musical tone forming means for forming musical tone signals based on a plurality of key data, a mixing means for mixing the musical tone signals, and a producing means for producing the mixed musical tone signal; a comparison means for detecting a plurality of key data corresponding to musical tones having the same pitch and a predetermined tone color relationship from the key data of musical tones to be mixed; and a modulation means for changing at least one tone element of the mixed musical tone signal to be produced from said producing means on the basis of the key data detected by said comparison means.
Claim 2
Dependent Claim
111 words
A performance apparatus comprising: a musical tone forming means for forming musical tone signals based on a plurality of key data, a mixing means for mixing the musical tone signals, and a producing means for producing the mixed musical tone signal; a comparison means for detecting a plurality of key data corresponding to musical tones having the same pitch and a predetermined tone color relationship from the key data of musical tones to be mixed; and a modulation means for changing at least one tone element of the mixed musical tone signal to be produced from said producing means on the basis of the key data detected by said comparison means.
