Sequence when parameters are changed by another controller
If the controller sends a parameter set request, a change notication is returned immediately.
However, if parameters change internally in the controlled device (this includes changes in parameters that occur as a result of a controller
operation on another parameter) or due to a request from another controller, a parameter change notication is received, as shown below.
The controller receiving a parameter change notication updates its own status if necessary.

The way in which parameter change notications are sent varies depending on the value notication mode specied in the MTX external control
protocol mode.
Advice for choosing normalized/raw value mode.
If you want to handle a value with a given range, such as in an MIDI controller,
• Set the value notication mode to normalized value notication mode, and specify the required resolution.
• Use setn/getn to perform processing from the controller.
• Apply changes to the controller according to NOTIFY setn.
Conversely, for a highly functional PC application where you want to use all the internal parameters,
• Set the MTX external control protocol mode to raw value mode.
• Use set/get to perform processing from the controller.
• Apply changes to the controller according to NOTIFY set.
• Use setn/getn for certain parameters when necessary.
