Abstract

In an automatic play apparatus for electronic music system, it is often desired to expand its function in universal and easy way. In this invention, at steps 100-140, the sequencer module records music performance data provided from an external device or it reproduces them. Sometimes it does both at the same time. In a series of processing at steps 100-140, the queue processing 200, 300 and 400 are introduced. In each queue processing, a part of the music performance data is memorized temporarily in Temporary Memory Area 200a, 300a and 400a, and the pointer, as an argument, corresponding to the memorized part of the music performance data is transferred to various plug-in programs which work as function expansion modules. The plug-in programs are thus enabled to read out the music performance data and write them, respectively from and in Temporary Memory Area 200a, 300a and 400a.

Claims

1. An automatic play apparatus for recording and reproducing a series of music performance data, said automatic play apparatus including queuing means and a memory area, said queuing means comprising:

memorizing means for memorizing temporarily a part of said series of music performance data in said memory area during said series of processing, and

transferring means for transferring an argument address to said temporarily memorized music performance data in said memory area to a function expansion module so that said function expansion module can read out said temporarily memorized music performance data from said memory area and write newly established music performance transferred data in said memory area.

2. An automatic play apparatus for recording and reproducing a series of music performance data, said automatic play apparatus including a plurality of queuing means and a memory area, said plurality of queuing means comprising respectively:

memorizing means for memorizing temporarily a part of said series of music performance data in said memory area during said series of processing, and

transferring means for transferring an argument address to said temporarily memorized music performance data in said memory area to a function expansion module so that said function expansion module can read out said temporarily memorized music performance data from said memory area and write newly established music performance transferred data in said memory area.

3. An automatic play apparatus according to claim 2, wherein said plurality of queuing means transfer argument addresses to different types of function expansion modules.

4. A function expansion device applied to an automatic play apparatus for recording and reproducing a series of music performance data, said device comprising:

receiving means for receiving an argument address to a part of said music performance data memorized temporarily in a memory area during said series of processing,

data reading means for reading out said memorized music performance data from said memory area based on said argument address.

5. A function expansion device according to claim 4, further comprising:

monitoring means for monitoring said read out music performance data.

6. A function expansion device applied to an automatic play apparatus for recording and reproducing a series of music performance data, said device comprising:

receiving means for receiving an argument address to a part of said music performance data memorized temporarily in a memory area during said series of processing,

data reading and writing means for reading out said memorized music performance data from said memory area and for writing newly established music performance data in said memory area based on said argument address.

7. A function expansion device according to claim 6, further comprising:

modifying means for modifying said read out music performance data to establish newly musical performance data.

8. A computer readable program storage medium storing a queue program applied to an automatic play apparatus for recording and reproducing a series of music performance data, said automatic play apparatus including a memory, said queue program containing executable instructions for causing a computer to perform the steps of:

memorizing temporarily a part of said series of music performance data in said memory during said series of processing, and

transferring an argument address to said temporarily memorized music performance data in said memory area to a function expansion module so that said function expansion module can read out said temporarily memorized music performance data from said memory area and write newly established music performance data in said memory area.

9. A computer readable program storage medium according to claim 8, wherein said queue program is incorporated in said series of processing.

10. A computer readable program storage medium storing a function expansion program applied to an automatic play apparatus for recording and reproducing a series of music performance data, said function expansion program containing executable instructions for causing a computer to perform the steps of:

receiving an argument address to a part of said music performance data memorized temporarily in a memory area during said series of processing,

reading out said memorized music performance data from said memory area based on said argument address.

11. A computer readable program storage medium according to claim 10, said function expansion program further containing the step of:

monitoring said read out music performance data.

12. A computer readable program storage medium storing a function expansion program applied to an automatic play apparatus for recording and reproducing a series of music performance data, said function expansion program containing executable instructions for causing a computer to perform the steps of:

receiving an argument address to a part of said music performance data memorized temporarily in a memory area during said series of processing,

reading out said memorized music performance data from said memory area based on said argument address,

writing newly established music performance data in said memory area based on said argument address.

13. A computer readable program storage medium according to claim 12, said function expansion program further containing the step of:

modifying said read out music performance data to establish newly musical performance data.
