A data processing apparatus that makes it possible for a user of a data processing apparatus to recognize whether or not descriptive contents of process definition tickets are executable on the data processing apparatus. Process definition tickets in which sequential processing flows for realizing functions are described are obtained, and it is determined whether or not the descriptive contents of the process definition tickets are executable on the data processing apparatus. A list of the process definition tickets whose descriptive contents have been determined as being executable on the data processing apparatus as a result of the determination is displayed in a manner being identifiable by the user. The user selects the process definition ticket whose descriptive contents are executable on the data processing apparatus from the list of the displayed process definition tickets, and the selection is received. The descriptive contents of the received process definition ticket are executed.
摘要:
An electronic musical instrument is controlled to receive key operation messages from a keyboard, sequencer or the like so as to control the data in such a manner that the disadvantages of a first-in first-out system and a map system are diminished and the newest data can be obtained rapidly. A reading device sequentially reads musical pitches out from a first memory so that it can be decided whether the values indicated on note-on/off flags in a second memory have the same state as the flags in a third memory. A command is issued to generate and/or truncate (or mute) musical tones based on key-depression (i.e., key state) data for the musical pitches registered in the second memory, if the flags are not identical with each other. On the other hand, the key-depression data are discarded without issuing any command if the flags are the same.

A performance information recording/playing apparatus corrects recording/playing errors in performance information which is reproduced from or recorded to a recording media by a performance information playing/(recording) device in accordance with event information. The performance information recording device includes a state information generating device which generates state information indicating a state of musical tone for a predetermined musical tone after a change has occurred in event information which represents a change in the predetermined musical tone, and a recording device for recording the event information and the state information in a recording media sequentially. The performance information playing device includes a playing device for playing event information which represents a change in a predetermined musical tone and state information which indicates a state of a musical tone for the predetermined musical tone, this information having recorded in a recording media. Further, the performance information playing device includes an event information correcting device for correcting errors in the event information, which is reproduced from the recording media, based on the state information which is reproduced in the same manner.

An automatic musical playing system includes an automatic playing apparatus and a sound generating unit. The playing apparatus includes: a first memory for storing musical playing data arranged to be sequentially preread; a calculator for calculating an actual length of time required to play music based on the preread musical data and/or for calculating an actual quantity of playing information in such data; a comparator for deciding whether or not the acutal length of time is less than a predetermined length of time, and/or whether or not the actual quantity is less than a predetermined quantity; a first reading device for sequentially prereading from the first memory, the musical data prior to an actual time for playing when the comparator decision/decisions is/are affirmative; and an output for outputting the preread musical data. The sound generating unit includes: an input for receiving preread musical data; a second memory for temporarily storing data from the input; a second reading device for sequentially reading from the second memory, data according to a predetermined timing; and a musical tone-generator which generates and/or mutes musical tones for playing music according to the preread musical data.

A performance information transmission system includes a performance information transmitter device and a performance information receiver device which are capable of correcting transmission errors in event information transmitted from the performance information transmitter device to the performance information receiver through a wire or radio communication. This correction does not require another transmission passes, cause a delay of the generation of the musical tone, or cause difficulties in restoring the burst error. The performance information transmitter device is equipped with state information generating device which generates state information for indicating the control state of a musical tone of a predetermined musical tone after a change has occurred in the event information. A transmit device transmits sequentially the event information and the state information generated by the state information generating device. Further, the performance information receiver device is equipped with a receiver for receiving sequentially an event information which causes a change in a predetermined musical tone and the state information indicating the control state of a musical tone of the predetermined musical tone. An event information correction device corrects the transmission error of the event information received by the receiver based on the state information received in the same manner.

An electronic musical instrument allots musical tone-generating channels to new musical tones by calculating an integrated residual generated volume or a substitute values corresponding thereto for each current musical tones; and determining which of musical tone-generating channels has a minimum such volume or substitute value. The instrument may, alternatively, allot a tone generating channel for a new musical tone by detecting a minimum envelope level of those already allotted musical tones; selecting those channels having envelope levels falling within a determined range defined based on and including the detected minimum level; and determining which channel selected by the selecting means has a minimum residual generated volumes or substitute values corresponding thereto. The residual generated volumes are determined by an equation: ##EQU1## wherein V(t) is an envelope level at an instant "t" during a period from the given instant "t.sub.o " and to the end point "t.sub.end " of the musical tone. The substitute values are given by a further equation;WL=LEV.sub.o *LEV.sub.o /(-RT.sub.o)wherein LEV.sub.o is the envelope level at the given instant, and RT.sub.o is a rate of change of the attenuating envelope level.

摘要:
An assigning device of an electronic musical instrument for selecting a musical tone-generating channel to assign a new musical tone is disclosed. The object of the invention is to minimize the sense of incongruity in a musical performance upon determining, preliminarily, the preferential order for the assignment of a new musical tone to the musical tone-generating channels.As to the musical tone-generating channels with the successive strike relation detected from among the channels being in a musical sound-generating condition, the content subject of the predetermined preferential order rule is altered. This altering is conducted so that the above-mentioned musical tone-generating channels with the successive strike relation are preferentially selected, and are assigned with new musical tones, according to the assigning order based on the predetermined preferential order rule, at least among musical tone-generating channels in the sound-generating condition. Under the altered content of the preferential order rule, the order of assigning a new musical tone to each channel is preliminarily determined according to the assigning order based on the predetermined preferential order rule.
