2.9 TEMPO MAP SETTING

Sending this overwrites Tempo Map and Beat Table

0xF0 System Exclusive Status number
0x47 AKAI System Exclusive Manufacturer ID number
id device ID
0x51 function code
0x5A DR4d/DPS12/DPS16 Product number
the number of 5 byte coded Tempo maps
the number of 5 byte coded Beat tables
Checksum 1
Tempo Data
:
Beat Data
:
Checksum 2 5 byte coded
0xF7 EOX:"End of System Exclusive" flag

The maximum number of tempo map is 200. the maximum number of beat table is 20.
If it exceeds the maximum, the exceeded data will be discarded.
Checksum 1 is lower 7 bit of the data bytes which is the sum
of the number of tempo map and the number of beat table. b7 is set to 0.

Tempo data is sent in reference to internal MIDI clock, 4 byte tempo code data
is 5 byte coded.
It will send the number of times as Tempo map. The table below is sent.

| |
|-----------------------------------|
| Internal MIDI clock (4 byte) |
|-----------------------------------|
| Tempo code (4 byte) |
|-----------------------------------|
| The next internal MIDI clock |
|-----------------------------------|
| The next tempo code |
|-----------------------------------|

| : |
:
Beat Data is sent as 4 bytes long word 5 byte coded which you set the number of
bar in the MS bytes of word and set the code of bar in the LS bytes of word. It
should be sent the same number of times as beat table. The table below is sent.

| |
|-----------------------------------|
| bar number (2 byte)) |
|-----------------------------------|
| bar code (2 byte) |
|-----------------------------------|
| The next bar number (2 byte) |
|-----------------------------------|
| The next bar code (2 byte) |
|-----------------------------------|
| : |
:
The checksum 2 is sent by 5 byte coded with the sum of long word before the 5
byte coded.
Internal MIDI clock is 0001.01.00 = 0 It starts from this number of clock.
a quarter note (crotchet) = 96 clock. at 4/4 beats 1 beat is 96 clock.
Tempo code is 10 times from that point. It means 120.0 is 1200 (by 16 decimal,
it is 0x4b0).
Bar number is 0001.01.00 = 0. It starts from this number of bar.
Bar code is 7- 5 bit = beat code, 4 - 0 bit = (1 bar beat -1).
Beat code is 0 = n/4, 1 = n/8, 2 = n/16, 3 = n/32. For example, 4/4 beats is
0x03.

RE: 5 byte coded

In order to set b7 to 0 in each byte of 4 byte long word, you should send it
separately by 5 byte.

1 byte
[7] 0
[6 - 0] data b31 - b25
2 byte
[7] 0
[6 - 0] data b24 - b18
3 byte
[7] 0
[6 - 0] data b17 - b11
4 byte
[7] 0
[6 - 0] data b10 - b4
5 byte
[7 - 4] 0000
[3 - 0] data b3 - b0

2.13 OTHER DATA REQUEST

This command is to support DPS16's exclusive functions. It requests each
setting data.
In subcommand you can use the subcommands which can set the value.

In other words, you can not use the commands which does not support setting the
value. It disregard when you designate other subcommands.
The returning data is same as "OTHER DATA SETTING".

2.14 OTHER DATA SETTING

This command is to support DPS16's exclusive functions. This command function
is determined by the subcommand. However, do not send next command during this
command is in operation. There is a possibility to create unexpected situation.
There is one subcommand in one exclusive and the number of byte is determined by
subcommand.
