Performance data processing apparatus
First Claim
1. A performance data processing apparatus, comprising:
- means for forming performance data consisting of a sequential train of note data each comprised of a pair of a note pitch datum indicative of a note pitch and a note duration datum indicative of a note duration, and of rest data each having no pitch datum and comprised of only a rest duration datum indicative of a rest duration, said sequential train of note data and rest data forming a progression of a piece of music;
means for judging whether or not a rest datum immediately following a note datum among said performance data has a duration shorter than a predetermined duration;
means for integrating, when a result of said judgement is YES, a combination of said note datum and said rest datum into a single integrated note datum having a note pitch of said note datum and having a note duration equal to a sum of the note duration of said note datum and the rest duration of said rest datum; and
means for producing revised performance data comprising a sequential train of note data and rest data which have not been integrated and said integrated note data.

Abstract
Performance data is comprised of a successive serial arrangement of note data formed with paired pitch data and note duration data and of rest data formed with only rest duration data and having no pitch data. A performance data processing apparatus judges whether a rest datum following a note datum is shorter than a predetermined duration, and in case the result of this judgment if YES, the apparatus integrates the rest datum and the note datum preceding the rest datum into an integrated note datum having a note pitch of the note datum and a note duration which is equal to the sum of the duration of the note datum and the duration of the rest datum, whereby, in case a music score is displayed or printed out based on the performance data, rests having a duration shorter than the predetermined duration are eliminated to prolong the duration of the respective preceding notes each by an amount of the duration of the eliminated rest. Thus, there is obtained a music score having inscriptions similar to those of an ordinary music score, and also there can be reproduced a performance which is free of an unnatural sense.

9. A performance data processing apparatus, comprising:
-
a keyboard; pitch data storing means to store note pitch data based on key data generated during the period from depression to release of a key of said keyboard; duration data generating means to generate duration data based on the duration of time said key is depressed and the duration of time said key is not depressed; duration data storing means to store duration data generated by said duration data generating means; and note duration integrating means receiving two successive pitch and duration data pairs which are stored in said pitch data storing means and said duration data storing means, and combining the duration datum for the succeeding data pair with the duration datum for the preceding data pair to thereby provide an integrated note duration data to be combined with the pitch data for the preceding data pair, when the preceding data pair contains a pitch datum and the succeeding data pair does not contain a pitch datum, and the duration datum for the succeeding data pair is shorter than a predetermined duration. - View Dependent Claims (10, 11)
