US 5,668,337 A · Automatic performance device having a note conversion function

Abstract

In a memory, there are stored a plurality of first automatic performance data and a plurality of second automatic performance data. Also, first note-conversion-related information is stored separately in corresponding relations to the individual first automatic performance data. Second note-conversion-related information is stored as information common to the second automatic performance data. In executing an automatic performance, the first and second automatic performance data are read out in accordance with the sequence of the performance so as to reproduce sounds based on note data contained in the read-out automatic performance data. During that time, notes of the first automatic performance data are converted in accordance with the first note-conversion-related information read out in correspondence with the first automatic performance data, while notes of the second automatic performance data are converted in accordance with the common second note-conversion-related information. Where automatic performance sounds are generatable in a plurality of channels, the note conversion process may be executed by processing automatic performance data to be generated in some of the channels as the first automatic performance data and automatic performance data to be generated in the other channels as the second automatic performance data.

An automatic performance device comprising:

first storage means for storing a plurality of automatic performance data for a plurality of channels, said first storage means also storing first information relative to note conversion in corresponding relations to at least some individual channels from among the channels;
second storage means for storing second information relative to note conversion independently of said first information stored in said first storage means, and
note conversion means for reading out the automatic performance data from said first storage means and note-converting the read-out automatic performance data on the basis of said first or second information, wherein said note conversion means note-converts the read-out automatic performance data on the basis of said first information for each of the channels for which said first information stored in said first storage means, while said note conversion means note-converts the read-out automatic performance data on the basis of said second information for each of the channels for which said first information is not stored in said first storage means, so as to generate automatic performance sounds based on note-converted data.

An automatic performance device comprising:

first storage means for storing a plurality of automatic performance data, said plurality of automatic performance data being classified into a plurality of attributes;
second storage means for storing first information relative to note conversion of the automatic performance data, said first information corresponding to specific attributes;
third storage means for storing second information relative to note conversion of the automatic performance and common to attributes other than said specific attributes;
readout means for reading out the automatic performance data from said first storage means in accordance with progression of an automatic performance, during which time said readout means, in correspondence with readout of first of said automatic performance data classified into one of the specific attributes, reads out from said second storage means said first information corresponding to the attribute of said first automatic performance data and also, in correspondence with readout of second said automatic performance data classified into one of the other attributes, reads out said second information from said third storage means, and
note conversion means for performing note conversion processing of note data contained in said first automatic performance data on the basis of said first information and performing note conversion processing of note data contained in said second automatic performance data on the basis of said second information, so as to generate note-converted automatic performance sounds.
