Using parameter changes to control parameters Using parameter changes to control parameters On the LS9, you can use a type of system exclusive messages called "parameter changes" to control specific events (fader/encoder operations, [ON] key on/off operations, etc.) as an alternative to using control changes or NRPN messages. For details on the parameter changes that can be transmitted and received, refer to "MIDI Data Format" in the appendix. 1 Connect the LS9 to your external device. 2 In the DISPLAY ACCESS section, press the [SETUP] key repeatedly to access the MISC SETUP screen. 3 Move the cursor to the MIDI SETUP popup button, and press the [ENTER] key to access the MIDI SETUP popup window. 4 As described in "Basic MIDI settings" (→ p. 178), select the ports and MIDI channels (device numbers) that will be used to transmit/receive parameter changes. NOTE • Parameter changes include a "device number" that specifies the transmitting or receiving device. The transmit (Tx) channel and receive (Rx) channel specified in the MIDI SETUP page are used as the device number. • Please be aware that if the device number included in the transmitted parameter change does not match the device number of the receiving LS9 console, the message will be ignored. • If parameter change and control change transmission/reception are turned on at the same time, a large amount of data will flood the MIDI port and cause overflows or other problems, so you should avoid this. 5 Use the Tx button and Rx button of the PARAMETER CHANGE field to turn on parameter change transmission/reception. In this state when you operate specific parameters on the LS9, the corresponding parameter change messages will be transmitted. If valid parameter change messages are transmitted from an external device, the parameters assigned to those parameter changes will be controlled. 18 MIDI LS9-16/32 Owner's Manual 185
