* The value specified by RPN will not be reset even by messages such as program

change or reset all controllers.

* Not recorded in the sequencer.

**RPN**

The RPN (Registered Parameter Number) messages are expanded control changes,

and each function of an RPN is described by the MIDI Standard.

To use these messages, you must first use RPN (controller number 100 and 110,

their order does not matter) to specify the parameter to be controlled, and then use

Data Entry messages (controller number 6, 38) to specify the value of the specified

parameter. Once an RPN parameter has been specified, all data entry messages

received on that channel will modify the value of that parameter. To prevent

accidents, it is recommended that you set RPN null (RPN number = 7FH 7FH)

when you have finished setting the value of the desired parameter. Refer to

“Examples of actual MIDI message” (p. 12).

On the normal mode of TD-6V, RPN can be used to modify the following

parameters. Regarding the value of each parameter, refer to Data Entry (Controller

number 6).

Data transmission

TD-6V can transmit and receive the various parameters using System Exclusive

messages.

The exclusive message of TD-6V’s data has a model ID of 00H 3FH and a device ID

of 10H (17). Device ID can be changed in TD-6V.

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.
