Specifying The Location Of The Data - Roland Edirol PCR-30 Owner's Manual

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.

DT2
(MSB/LSB)
7bit/7bit
DT3
(LSB/MSB)
4bit/4bit/
DT4
4bit/4bit
* 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.
