Claims
- 1. A tone data recording and reproducing device which comprises:
- a storage device storing a data file having tone data of plural channels recorded in an interleaved state;
- a first buffer memory into which the tone data read out from said storage device is fetched;
- interleave cancellation means for reading out the tone data from said first buffer memory and releasing the read-out tone data from the interleaved state so as to provide separate tone data for each of the channels;
- a second buffer memory for storing, separately for each of the channels, interleaved-state-released tone data provided from said interleave cancellation means; and
- readout means for reading out the tone data stored in said second buffer memory.
- 2. A tone data recording and reproducing device which comprises:
- a storage device storing plural data files each having tone data recorded therein;
- means for selecting either of a first mode for reproducing the data file having tone data of plural channels recorded therein in an interleaved state, and a second mode for permitting a simultaneous reproduction of plural data files each having not-interleaved tone data recorded therein;
- a first buffer memory to which the tone data read out from said storage device is fetched;
- a second buffer memory having plural predetermined storage areas;
- first transfer control means for, in said first mode, reading out the tone data from said first buffer memory and releasing the read-out tone data from the interleaved state, so as to cause interleaved-state-released tone data to be stored into respective storage areas of said second buffer memory separately for each of the channels;
- second transfer control means for, in said second mode, reading out the tone data of the individual data files from said first buffer memory so as to store the read-out tone data into the respective store areas of said second buffer memory; and
- readout means for reading out the tone data stored in the respective storage areas of said second buffer memory.
- 3. A tone data recording and reproducing device which comprises:
- first memory means storing tone waveform data of plural sounds in an interleaved state;
- assignment channel designation means for designating reproduction channels to which interleaved tone waveform data of the plural sounds should be assigned;
- second memory means for storing tone waveform data for each of the reproduction channels;
- interleave cancellation means for reading out the tone waveform data from said first memory means to release the read-out data from the interleaved state, and distributing the interleaved-state-released tone waveform data of the individual sounds in correspondence to the channels designated by said channel designation means so as to write the tone waveform data into said second memory means; and
- readout means for reading out the tone waveform data stored in said second memory means, independently for each of the reproduction channels.
- 4. A tone data recording and reproducing device which comprises:
- first memory means storing tone waveform data of plural sounds in an interleaved state;
- interleave cancellation means for rapidly reading out a part of the tone waveform data stored in said first memory means to release the read-out data from the interleaved state;
- second memory means for storing tone waveform data for each channel; and
- readout means for, for each reproduction channel, reading out the tone waveform data stored in said second memory means at a predetermined readout rate.
- 5. A tone data recording and reproducing device which comprises:
- first memory means storing tone waveform data of plural sounds in an interleaved state;
- second memory means for storing tone waveform data for each of a predetermined number of reproduction channels:
- channel designation means for setting time-divisional time slots that are equivalent in number to the interleaved sounds and designating individual reproduction channels in correspondence to the time slots;
- interleave cancellation means for reading out the tone waveform data from said first memory means to release the read-out data from the interleaved state in correspondence to the time slots, and distributing the interleaved-state-released tone waveform data to the reproduction channels designated in correspondence to the time slots so as to write the tone waveform data into said second memory means; and
- readout means for reading out the tone waveform data stored in said second memory means.
- 6. A tone data recording and reproducing device which comprises:
- first storage means storing plural data files each having tone waveform data recorded therein, some of the data files having tone waveform data of plural sounds recorded therein in an interleaved state, other data file having not-interleaved tone waveform data recorded therein;
- selection means for selecting data file to be reproduced, said selection means permitting a selection of a plurality of the data files;
- second storage means;
- readout control means for reading out from said first storage means the tone waveform data of a data file selected by said selection means, so as to store the read-out data into said storage means;
- channel designation means for designating reproduction channels through which tone generation for the selected data file should be effected, said channel designation means, in the case of said data file having tone waveform data of plural sounds recorded in an interleaved state, designating a necessary number of the channels corresponding to the number of interleaved sounds;
- third storage means provided in corresponding relation to the reproduction channels;
- transfer control means for, for each of the data filed, reading out the tone waveform data stored in said second storage means to store the read-out data into said third storage means in correspondence to the designated reproduction channels, said transfer control means, in the case of said data file having tone waveform data of plural sounds recorded in an interleaved state, releasing the tone waveform data from the interleaved state so as to store interleaved-state-released data into said storage means in correspondence to the designated reproduction channels; and
- readout means for, for each of the reproduction channels, reading out the tone waveform data stored in said third storage means at an independent readout rate.
