■System Realtime Message
● Active Sensing
Status
FEH
*When Active Sensing is received, the unit will begin monitoring the intervals of all
further messages. While monitoring, if the interval between messages exceeds 360 msec,
the same processing will be carried out as when All Notes Off and Reset All Controllers
are received, and message interval monitoring will be halted.
■System Exclusive Message
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 F-50 are; Universal Non-realtime System
Exclusive messages, and Data Set (DT1).
● Universal Non-realtime System Exclusive Messages
❍ Identity Request Message
Status Data byte Status
F0H 7EH, dev, 06H, 01H F7H
Byte Explanation
FOH Exclusive status
7EH ID number (universal non-realtime message)
dev Device ID (dev: UNIT#-1)
06H Sub ID#1 (General Information)
01H Sub ID#2 (Identity Request)
F7H EOX (End Of Exclusive)
* The “dev” is own device number (UNIT#-1) or 7FH (Broadcast).
*UNIT# is always the same as the current MIDI Tx/Rx channel.
● Data transmission
F-50 can transmit and receive the various parameters using System Exclusive messages.
The exclusive message of F-50 data has a model ID of 1AH, and device ID is defined by
MIDI UNIT NUMBER.
UNIT NUMBER is always the same as the current MIDI Tx/Rx channel.
❍ Data set 1 DT1
This is the message that actually performs data transmission, and is used when you wish to
transmit the data.
Status Data byte Status
F0H 41H, dev, 1AH, 12H, aaH, bbH, ddH, sum F7H
Byte Explanation
F0H Exclusive status
41H ID number (Roland)
dev Device ID (dev: UNIT#-1)
1AH Model ID (F-50)
12H Command ID (DT1)
aaH Address MSB: upper byte of the starting address of the transmitted data
bbH Address LSB: lower byte of the starting address of the transmitted data
ddH Data: the actual data to be transmitted.
sum Checksum
F7H EOX (End Of Exclusive)
* If “Data Set 1” is transmitted successively, there must be an interval of at least 40 msec
between packets.
* Regarding the address please refer to section 3 (Parameter Address Map).
* Regarding the checksum please refer to section 4 (Supplementary material).
