Specifying the location of the data

Here’s how to specify the location and data type of the variable portion (data) within a system
exclusive message.
The range of data values will be the default range in the case of Basic mode or Advanced mode 3.
In the case of Advanced modes 1 and 4, you can specify the range of data values.
For an actual example, please read the Sys Ex,ASSIGN section

“Master Volume”

(p. 143).

1. Press the

[DATA]

key at the location where you want to input the data.

The display will indicate “DT0”.

2. Use the

[0]

–

[4]

keys to select the type of data.

In the case of DT1--DT4 (data consisting of two or more bytes), a data location will automatically be
allocated for the next byte, and "-DT" will be displayed. (This cannot be changed.)

3. Press the

[ENTER]

button.

4. If you selected DT1 through DT4, the display will indicate “-DT”.

Press the

[ENTER]

button.
