You. However, when performing recording and playback at the same time,
If you increase the number of tracks to be played,
Decrease. Because the processing capacity of hardware is limited
is there. Specifically, in the present apparatus, a 16-bit mode
Mode and 24-bit mode. 16-bit mode
Mode is a mode in which the number of bits of data to be recorded is 16 bits.
The 24-bit mode is used for recording data bits.
In this mode, the number of bits is 24 bits. Once generated
The bit number of the sound data of the song

When the number of tracks is 0 to 8,
Reproduction is possible. Number of tracks to be recorded simultaneously is 9-1
When the number is 6, it is possible to play back 8 tracks at the same time.
You. The eight tracks to be played are the same tracks as the tracks to be recorded.
It may be a check. When recording on a stereo track

Are automatically set). That is, in FIG.
In the leftmost state 901, track 1 is in a recording state,
When you turn on the recording track switches 2 and 3 from here,
Tracks 1 to 3 are in the recording state as in the state 902 of FIG.
You. At this time, since the number of recording tracks has reached 3,
The possible number of tracks is 12. So, the big number
Automatically mutes tracks 13-16,
12 tracks from 1 to 12
You. Further, from the state 902, the recording track switch
When switches 4 and 5 are turned on,
The recordings 1 to 5 are in the recording state. At this time, the recording track
Since the number of tracks becomes five, the number of reproducible tracks becomes eight.
You. Therefore, tracks 9-1 are newly added from the larger number.
Automatically mutes 2 and 8 tracks 1-8
I like to play. Further, from the state 903, the recording track switch
When switches 6 and 7 are turned on,
The recordings 1 to 7 are in the recording state. At this time, the recording track
Since the number of tracks becomes 7, the number of reproducible tracks becomes 8.
You. In this case, 8 tracks of tracks 1 to 8
Can be played, so mute must be increased in state 904.
No need. Further, from the state 904, the recording track switch
When switches 8 and 9 are turned on, the
The recordings 1 to 9 are in the recording state. At this time, the recording track
Since the number of tracks becomes 9, the number of reproducible tracks becomes 0.
You. So all remaining tracks are automatically muted
In this case, the number of reproduction tracks is set to 0. FIG. 9B shows eight signals in the 16-bit mode.
Recording track and two mute settings
Then, the ninth track was specified as the recording track.
The state of the change in the case is shown. In this case, the six missing
Auto setting. That is, No. 1 in FIG.
In state 911 on the left, tracks 3 and 4 are muted.
From here, the recording track switches 1, 2, 5, 6,
When 7, 8, 11, and 13 are turned on, the next state 912 is displayed.
Thus, those turned-on tracks are in the recording state. This
At the time, the number of recording tracks became 8, so it can be played
The number of tracks becomes 16. Therefore, it is necessary to increase mute
Since there is no need, the mute state is unchanged. Further, from the state 912, the recording track switch
When the switch 12 is turned on, the sound is recorded as shown in the next state 913.
Now that the number of tracks is nine, the number of tracks that can be played is
It becomes 8. Therefore, a new track from the higher number
11-16 are automatically muted and tracks 1-3,6
8 to 10 tracks are reproduced. The state 913 to the state 914 are muted.
This is an example in which a track is changed. From state 913, one
Add a mute for the rack and replace it with another one
The track is unmuted. Thus, the re-
If there are more mute than can not be born,
Tracks to be muted can be freely changed.
Conversely, if the number of mute is less than
It cannot be set to be. In that case,
The mute is not released even if the operation of releasing the mute is performed. FIG. 10 shows the Quick REC key of FIG.
