SpaceMap Control
The LX-300s can receive external serial or MIDI data to control the panning of matrix buses by the SpaceMap al-
gorithm. This has many applications, including parade audio localization, interactive VR development, and theatrical
audio panning.
The protocol supports assigning a given bus to a SpaceMap, and setting the location of that bus within that SpaceMap.
The "Set parameter and update host command" is used to assign the SpaceMap and the bus.
The category ID is 73 (decimal) and index 1 is the bus. Index 2 is not used. (In the following examples the value
0x7F is used for the Frame ID, thereby suppressing CHECKSUM use. Please see the Checksum entry at the front
of this manual for details.)
