Data transmission

TD-6 can transmit and receive the various parameters using System Exclusive
messages.
The exclusive message of TD-6s data has a model ID of 00H 3FH and a device ID of
10H (17). Device ID can be changed in TD-6.'

Request data 1 RQ1 (11H)

This message requests the other device to send data. The Address and Size
determine the type and amount of data to be sent.
When a Data Request message is received, if the device is ready to transmit data
and if the address and size are appropriate, the requested data will be transmitted
as a "Data Set 1 (DT1)" message. If not, nothing will be transmitted.
