MIDI Implementation
The VS-2480/2480CD can transfer and receive the internal parameters information using
system exclusive messages, and also can be controlled by the external devices using system
exclusive message.
The VS-2480/2480CD can transmit and receive Universal System Exclusive messages, Data
Request (RQ1) and Data set (DT1) as the System Exclusive Message.
❍
About Model ID
The Model ID of the VS-2480/2480CD is 00H,40H as for Data Request (RQ1) and Data set
(DT1). The VS-2480/2480CD also can receive 00H,40H (VS-2480/2480CD) and 00,36H (VE-
7000).
❍
About Device ID
System Exclusive messages are not assigned to any particular MIDI channel. Instead, they
have their own special control parameter called device ID.
The roland system exclusive messages use device IDs to specify multiple VS-2480/2480CD
units.
The VS-2480/2480CD sends system exclusive messages using 00H-1FH, and receives the
system exclusive messages whose device ID is same as its device ID and 7FH.
the value of the device ID is the value set on the UTILITY-MIDI screens DEVICE ID minus
one.
