Roland VC-200HD Command Reference

VC-200HD/VC-300HD Command Reference
Command Overview
The basic command syntax consists of a line of ASCII code: "stx" followed by "3 letters (uppercase)" and then a ";"
(semicolon).
The three letters indicate the command type. Also, when there are parameters for the command, a colon is inserted
between the three letters and the parameter. If there are multiple parameters, they are separated with a comma (,).
"stx" This is a signal name (code number 02H (hexadecimal) in ASCII code. It is a control code indicating the start of
a command.
":" This is a code for this device to recognize the separation of the command and its parameters.
";" This code is for this device to recognize the end of a command.
Example 1) When sending an input format request, the ASCII code line "stxVIF;" is sent.
Example 2) When loading Preset3, the ASCII code line "stxPSE:2;" is sent.
