Abstract

There is provided a musical composition-reproducing device and a musical composition-reproducing method that make it possible to make the most of many sounding channels and are capable of imparting an effect to musical tones without providing a special effect circuit. Musical composition data read from a musical composition data file FL is read out as data of a track 1 comprised of 4 channels, and is also copied and read out as data of a track 2, a track 3 and a track 4. Delay times of delaying means D1 to D3 and attenuations of attenuating means G1 to G3 are determined as being values t1 to t3 and g1 to g3, respectively, in accordance with effect parameter information. A sequencer SQ reproduces three effect sounding sequence data in the tracks 2 to 4, which is delayed by the delay times t1 to t3 and attenuated by the attenuations g1 to g3, as an effect sound providing a reverberation to musical tones reproduced based on the sequence data in the track 1 by using 12 channels among 16 channels.

Claims

1. A musical composition-reproducing device comprising:

a musical composition-reproducing unit that has n×

m sounding channels, and reproduces musical composition data each comprised of m sequence data including performance data of n channels, wherein n is a positive integer and m is an integer of not less than 2;

a detecting unit that detects a number k of sequence data of musical composition data to be reproduced by said musical composition-reproducing unit; and

a control unit that controls said musical composition-reproducing unit to reproduce the sequence data of the musical composition data by using a part of the n×

m sounding channels when the detected number k of the sequence data is less than the number m of sequence data that can be reproduced by said musical composition-reproducing unit while generating an effect sound related to the sequence data being reproduced by using at least one free channel among the n×

m sounding channels.

2. A musical composition-reproducing device according to claim 1, wherein said control unit controls said musical composition-reproducing unit so as to copy at least one sequence data to be reproduced and change control information for sequence data obtained by the copying according to at least one effect parameter to thereby generate at least one effect imparting sequence data, and reproduce the at least one sequence data and the generated at least one effect imparting sequence data.

3. A musical composition-reproducing device according to claim 1, wherein if effect information is added to at least one sequence data among the k sequence data, said control unit controls said musical composition-reproducing unit so as to copy the at least one sequence data and change control information for sequence data included in the copied sequence data, according to the effect information to thereby generate at least one effect imparting sequence data, and generate the effect sound by reproducing the generated at least one effect imparting sequence data by using the at least one free channel.

9. A musical composition-reproducing device according to claim 3, wherein when the musical composition data is comprised of sequence data and effect imparting sequence data, said control unit controls said musical composition-reproducing unit so as to reproduce the sequence data of the musical composition data by using a part of the n×

m sounding channels without generating the effect imparting sequence data, and generate the effect sound by reproducing the effect imparting sequence data by using at least one free channel among the n×

m sounding channels.

4. A musical composition-reproducing device comprising:

a musical composition-reproducing unit that has n×

m sounding channels, and reproduces musical composition data each comprised of m sequence data including performance data of n channels, wherein n is a positive integer and m in an integer of not less than 2; and

a control unit that controls said musical composition-reproducing to reproduce k sequence data among the m sequence data included in the musical composition data using k×

n sounding channels among the n×

m sounding channels while generating an effect sound related to at least one sequence data among the k sequence data by using at least one free channel among n×

(m−

k) sounding channels, wherein k is a positive integer that is less than m.

5. A portable terminal device comprising:

a musical composition-reproducing device comprised of a musical composition-reproducing unit that has n×

m sounding channels, and reproduces musical composition data each comprised of m sequence data including performance data of n channels, and a control unit that controls said musical composition-reproducing unit to reproduce k sequence data included in the musical composition data by using k×

n sounding channels among the n×

m sounding channels while generating an effect sound related to at least one sequence data among the k sequence data by using at least one free channel among n×

(m−

k) sounding channels, wherein

n is a positive integer, m is an integer of not less than 2, and k is a positive integer that is less than m, and

said musical composition-reproducing device reproduces the musical composition data to thereby output an incoming call melody or a hold sound provided with the at least one effect.

6. A portable terminal device comprising:

a musical composition-reproducing device comprised of a musical composition-reproducing unit that has n×

m sounding channels, and reproduces musical composition data each comprised of m sequence data including performance data of n channels, and a control unit that controls said musical composition-reproducing unit to reproduce k sequence data included in the musical composition data by using k×

n sounding channels among the n×

m sounding channels while generating an effect sound related to at least one sequence data among the k sequence data by using at least one free channel among n×

(m−

k) sounding channels, wherein n is a positive integer, m is an integer of not less than 2, and k is a positive integer that is less than m;

a storage device that stores the musical composition data; and

a reading device that reads the musical composition data from said storage device, wherein

said musical composition-reproducing device reproduces the musical composition data read by said reading device to thereby reproduce a musical composition provided with at least one effect.

7. A musical composition-reproducing method comprising:

reproducing musical composition data each comprised of m sequence data including performance data of n channels by using n×

m sounding channels, wherein n is an integer;

detecting a number k of sequence data of musical composition data to be reproduced during reproduction of the musical composition data; and

controlling the reproduction of the musical composition data so as to reproduce the sequence data of the musical composition data by using a part of the n×

m sounding channels when the detected number k of the sequence data is less than the number m of sequence data that can be reproduced during reproduction of the musical composition data while generating an effect sound related to the sequence data being reproduced by using at least one free channel among the n×

m sounding channels.

8. A musical composition-reproducing method comprising:

reproducing musical composition data each comprised of m sequence data including performance data of n channels by using n×

m sounding channels, wherein n is an integer and m is an integer of not less than 2; and

controlling the reproduction of the musical composition data so as to reproduce k sequence data included in musical composition data by using k×

n sounding channels among n×
