4. Command Sequence
4.4. Meter data request/query sequence
The controller requests meter data by specifying the meter data address and the minimum transmission interval.
The meter transmission stops after 10 seconds. To continue receiving data, make another request before the 10 seconds pass.

4.5. Sequence when parameters are changed by another controller
If the controller sends a parameter set request, a change notification 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 notification is received, as
shown below.
The controller receiving a parameter change notification updates its own status if necessary.

The way in which parameter change notifications are sent varies depending on the value notification mode specified in the MTX external
control protocol mode.
If you want to handle a value with a given range, such as in an MIDI controller,
• Set the value notification mode to normalized value notification 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.
