Abstract
Abstract An auto-play apparatus having an auto-play data memory for storing a note data string of an auto-accompaniment pattern, and a tone generator for generating tones on the basis of the note data string read out from the auto-play data memory. The auto-play apparatus includes an intonation pattern memory for storing intonation patterns of a plurality of levels corresponding to different degrees of tone-up of a performance. The intonation value is changed upon operation of an operation unit, and a note data string is read out from the auto-play data memory on the basis of intonation pattern data corresponding to the new intonation value. The readout note data string is supplied to the tone generator. The intonation pattern data of different levels includes at least designation information for designating different read positions in the auto-play data memory, and different tone volume information, different tone color information, and different instrument information to be provided to the readout note data. The intonation pattern data is partially rewritten in a data edit mode, thus changing the tone-up pattern of an accompaniment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
178 words
An auto-play apparatus comprising: note data memory means for storing an auto-accompaniment note data string; tone generation means for generating a tone on the basis of the note data string read from said note data memory means; intonation pattern memory means for storing intonation patterns of different levels corresponding to degrees of tone-up of a performance; intonation value setting means for setting an intonation value corresponding to the different levels; and tone control means for controlling the note data string read from said note data memory means on the basis of tone intonation patterns corresponding to the set intonation value, and outputting the note data string to said tone generation means, wherein the tone intonation patterns of different levels include at least one of designation information for designating different read positions in said note data memory means, different tone volume information, different tone color information, and different instrument information to be applied to the note data string read from said note data memory means, and said tone control means includes edit means for editing the tone intonation patterns.
Claim 2
Dependent Claim
178 words
An auto-play apparatus comprising: note data memory means for storing an auto-accompaniment note data string; tone generation means for generating a tone on the basis of the note data string read from said note data memory means; intonation pattern memory means for storing intonation patterns of different levels corresponding to degrees of tone-up of a performance; intonation value setting means for setting an intonation value corresponding to the different levels; and tone control means for controlling the note data string read from said note data memory means on the basis of tone intonation patterns corresponding to the set intonation value, and outputting the note data string to said tone generation means, wherein the tone intonation patterns of different levels include at least one of designation information for designating different read positions in said note data memory means, different tone volume information, different tone color information, and different instrument information to be applied to the note data string read from said note data memory means, and said tone control means includes edit means for editing the tone intonation patterns.
Claim 3
Dependent Claim
30 words
The apparatus of claim 1, further comprising edit operation means including input means for inputting the different tone volume information, the different tone color information, and the different instrument information.
Claim 4
Dependent Claim
33 words
The apparatus of claim 1, further comprising: a ROM for storing the intonation patterns and the accompaniment note data string; and a RAM for storing the intonation patterns edited by said edit means.
Claim 5
Dependent Claim
26 words
The apparatus of claim 1, wherein said tone control means includes an identification table indicating, in units of intonation levels, whether the intonation patterns are edited.
Claim 6
Dependent Claim
20 words
The apparatus of claim 1, wherein said intonation value setting means includes operation means for incrementing/decrementing the set intonation value.
Claim 7
Dependent Claim
14 words
The apparatus of claim 1, each intonation pattern including chord, bass, and drum tones.
Claim 8
Dependent Claim
34 words
The apparatus of claim 1, wherein the different tone volume information is a difference value to be added to tone volume information of the note data string read from said note data memory means.
Claim 9
Dependent Claim
20 words
The apparatus of claim 1, wherein the different instrument information includes intonation pattern data tracks assigned to a drum type.
Claim 10
Dependent Claim
67 words
The apparatus of claim 8, wherein the intonation pattern data tracks assigned to a drum type include instrument conversion information having new instrument type data and current instrument type data of the note data string read from said note data memory means, wherein said current instrument type data of the note data string of the note data memory means is replaced with said new instrument type data.
