ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a remix apparatus and method for dividing previously generated musical tone pattern data into a plurality of musical tone data (hereinafter referred to as “musical tone piece data”) and combining the musical tone piece data obtained by the division to generate new musical tone pattern data, and a storage medium storing a program for implementing the method.
2. Prior Art
A conventional remix apparatus for generating new musical tone pattern data from previously generated musical tone pattern data is known, for example, from Japanese Laid-Open Patent Publication (Kokai) No. 6-95668.
This remix apparatus designates ones of plural previously generated and stored musical tone pattern data which are to be selected as well as switching timing therefor and reads out the designated musical tone pattern data at the designated switching time to sequentially regenerate the data starting with the one indicated by the switching timing to thereby generate new musical tone pattern data.
With the above conventional remix apparatus, however, the newly generated musical tone pattern data is obtained by cutting out some of the plural musical tone pattern data and joining these data together, and each of the musical tone data constituting the new musical tone pattern data is located at the same position as the corresponding original musical tone pattern data. That is, the tempo (the tempo, as used herein, does not refer to the general tempo of performance but to the tempo in a local portion such as one beat) and groove of the newly generated musical tone pattern data still depend on the tempo and groove of the corresponding positions of the original plural musical tone pattern data. Thus, the conventional remix apparatus still has room for improvement on this point.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a remix apparatus and method that can generate new musical tone pattern data with new tempo and groove while partly maintaining the tempo and groove of the original musical tone pattern data, and a recording medium storing a program for implementing the method.
It is another object of the present invention to provide a remix apparatus and method that can generate musical tone pattern data with rhythmicity or rhythmical sense even from original musical tone pattern data which lack rhythmicity or rhythmical sense, and a recording medium storing a program for implementing the method.
It is a further object of the present invention to provide a remix apparatus and method that can generate new musical tone waveform data by processing harmonic characteristics of musical tone waveform data for use in a waveform memory tone generator, an FM (frequency modulation) tone generator, or the like, and a recording medium storing a program for implementing the method.
According to a first aspect of the present invention, there is provided a remix apparatus comprising a division device that divides musical tone pattern data having a first predetermined length into a plurality of first musical tone piece data each having a second predetermined length smaller than the first predetermined length, and divides the musical tone pattern data into a plurality of second musical tone piece data each having a third predetermined length smaller than the first predetermined length and different from the second predetermined length, and a generation device that operates based on a rearranging pattern indicative of an arrangement of lengths of ones of musical tone piece data obtained by division by the division device to be rearranged in rearranging the musical tone piece data, to generate new musical tone pattern data by selecting and rearranging at least one of the plurality of first musical tone piece data in at least one position for which the rearranging pattern indicates the second predetermined length, and selecting and rearranging at least one of the plurality of second musical tone piece data in at least one position for which the rearranging pattern indicates the third predetermined length.
According to a first aspect of the present invention, there is also provided a remix method comprising a division step of dividing musical tone pattern data having a first predetermined length into a plurality of first musical tone piece data each having a second predetermined length smaller than the first predetermined length, and dividing the musical tone pattern data into a plurality of second musical tone piece data each having a third predetermined length smaller than the first predetermined length and different from the second predetermined length, and a generation step of operating based on a rearranging pattern indicative of an arrangement of lengths of ones of musical tone piece data obtained by division by the division step to be rearranged in rearranging the musical tone piece data, to generate new musical tone pattern data by selecting and rearranging at least one of the plurality of first musical tone piece data in at least one position for which the rearranging pattern indicates the second predetermined length, and selecting and rearranging at least one of the plurality of second musical tone piece data in at least one position for which the rearranging pattern indicates the third predetermined length.
Thus, according to the first aspect, by changing the manner of dividing the musical tone piece data depending on the length of each part of the rearranging pattern, portions of the musical tone pattern from which sounds characteristic of this pattern are generated can be extracted and rearranged depending on the beats of the musical tone pattern data (for example, 4 beats, 8 beats, or 16 beats), thereby enabling the rearrangement of the musical tone piece data with the nuance of the original musical tone pattern data maintained.
According to a second aspect of the present invention, there is provided a remix device comprising a division device that divides musical tone data having a predetermined length into a plurality of musical tone piece data each having a length smaller than the predetermined length, a first selection device that selects one of a plurality of rearranging patterns each indicative of an arrangement of lengths of ones of musical tone piece data obtained by division by the division device to be rearranged in rearranging the musical tone piece data, a second selection device that selects one of a plurality of ratio patterns each indicative of positions of ones of the musical tone piece data obtained by division by the division device to be controlled in rearranging the musical tone piece data and also indicative of contents of control thereof, and a generation device that generates new musical tone pattern data by sequentially selecting ones of the plural musical tone piece data which have lengths indicated by the selected rearranging pattern, subjecting ones of the selected musical tone piece data which are located at positions indicated by the selected ratio pattern, to control having contents indicated by the selected ratio pattern, and then rearranging the controlled musical tone piece data.
According to the second aspect, there is also provided a remix method comprising a division step of dividing musical tone data having a predetermined length into a plurality of musical tone piece data each having a length smaller than the predetermined length, a first selection step of selecting one of a plurality of rearranging patterns each indicative of an arrangement of lengths of ones of musical tone piece data obtained by division by the division step to be rearranged in rearranging the musical tone piece data, a second selection step of selecting one of a plurality of ratio patterns each indicative of positions of ones of the musical tone piece data obtained by division by the division step to be controlled in rearranging the musical tone piece data and also indicative of contents of control thereof, and a generation step of generating new musical tone pattern data by sequentially s
