LUSP Requests (06 hex)
The request message class was included to allow external systems "request" information/data from the System. The System responds to "requests" by outputting a SYSEX message with the same message class as the "Request type" which identifies the request.

Note that the "Request Type" of the request is the "Message Type" of the response.

The arguments vary depending on the "Request Type". As stated above, the "Request Type" is also the "Message Type" of the SYSEX message that the System will transmit in response to the request. Refer to the specific "Message Type" sections for information about the arguments to those requests.
