Therefore, the determination result of step 146 is negative (N).
And returns to step 142. And step 14
Steps 2 and below are performed in the same manner as described above. In this way, even if the check is performed up to TRN = 5,
If there is no assigned track, T
After the RN becomes 6, the determination result of step 144 is negative.
(N). This means that track 6 has no instrument code
Not assigned (PICODE (M, 6) = 0
This is because that. Thereafter, at step 146, TRN =
6, PTNNUM (M) = 5, so the judgment result is positive.
Determinate (Y), and step 1 through step 148
Move to 50. Then, Step 150 and Step 15
In 2, the writing process for TRN = 6 is the same as described above.
It is performed. Further, as described above, TRN = 2, 3, 4,
In the process of sequentially examining in the order of 5, in this pad operation
If the rhythm sound type is already assigned to any track
If it is found, then from step 144
Move to step 152, where the TRN
The writing process of the timing information is performed for the member.

If it is found that, at that time step 144 to step
Move to 152, and write timing information regarding TRN = 4
Is performed. In this case, TRN = 5
I don't look at racks. The processing in steps 132 to 152 described above
According to this, every time the rhythm sound type is specified, the rhythm sound
It is determined whether the type has been assigned to any of the tracks,
If there is a track that has been assigned,
Type-related timing information is written while allocation
If there is no track already assigned, one of the unassigned tracks
The rhythm sound type is assigned and the rhythm sound type is
Relevant timing information is written. And this
