or “MIDI ➝ DELAY”.
● Start
Status
FAH
* Recognized only when the “Sync Mode” of the Pattern Global is set at “AUTO”, “EXT”
or REMOTE.

● Active Sensing
Status
FEH
* When Active Sensing is received, the unit will begin monitoring the intervals of all fur-
ther messages. While monitoring, if the interval between messages exceeds about 420
ms, the same processing will be carried out as when All Sounds Off, All Notes Off and
Reset All Controllers are received, and message interval monitoring will be halted.
■ System Exclusive Message
* Following System Exclusive Messages cannot be recorded.
Status Data byte Status
F0H iiH, ddH, ......,eeH F7H
F0H: System Exclusive Message status
ii = ID number: an ID number (manufacturer ID) to indicate the manufacturer whose
Exclusive message this is. Roland’s manufacturer ID is 41H.
ID numbers 7EH and 7FH are extensions of the MIDI standard;
Universal Non-realtime Messages (7EH) and Universal Realtime
Messages (7FH).
dd,...,ee = data: 00H - 7FH (0 - 127)
F7H: EOX (End Of Exclusive)
The System Exclusive Messages received by the TD-10 are; Universal Non-realtime System
Exclusive Messages, Data Requests (RQ1), and Data Set (DT1).
● Universal Non-realtime System Exclusive Messages
❍ Inquiry request
Status Data byte Status
F0H 7EH, dev, 06H, 01H F7H
Byte Explanation
F0H Exclusive status
7EH ID number (universal non-realtime message)
dev Device ID (dev: 00H - 1FH (1 - 32) Initial value is 10H (17))
06H,01H Inquiry request
F7H EOX (End Of Exclusive)
* Even if the Device ID is 7FH (Broadcast), Inquiry Reply message will be transmitted.
* When Inquiry Request is received, Inquiry Reply message will be transmitted.
● Data transmission
TD-10 can transmit and receive the various parameters using System Exclusive messages.
The exclusive message of TD-10’s data has a model ID of 00H 0AH and a device ID of 10H
(17). Device ID can be changed in TD-10.
❍ 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.

* The amount of data that can be transmitted at once time will depend on the type of
data, and data must be requested using a specific starting address and size. Refer to the
Address and Size listed in Parameter Dump Request (Page 158).
* Regarding the checksum please refer to Page 163.
❍ Data set 1 DT1 (12H)
This is the message that actually performs data transmission, and is used when you wish to
transmit the data.
