 System Realtime Messages
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
420 ms, the same processing will be carried out as when All Sounds O is received,
and message interval monitoring will be halted.
 System Exclusive Messages
Status Data byte Status
F0H iiH, ddH, ......, eeH F7H
F0H: System Exclusive Messages Status
ii = ID number: 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 this instrument are Universal Non-
realtime System Exclusive messages.

2. Data Transmission
 Channel Voice Messages
* The following channel voice messages are transmitted on the channel specied as
the MIDI Channel (MENU --> SYS --> MIDI --> MIDI).
* Not transmitted when MIDI Channel is set to “OFF.”
* Channel Voice messages linked to the D-BEAM are not transmitted when the
[D-BEAM] button is OFF.
Note O
Status 2nd byte 3rd byte
8nH kkH vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = note number: 00H–7FH (0–127)
vv = note o velocity: 00H–7FH (0–127)
* Transmitted the note numbers which are specied by the kit.
* When the pad or D-BEAM TriggerMode (MENU --> INST --> SETUP) is set to “GATE,”
note o is transmitted after the interval specied in GateTime (MENU --> KIT -->
MIDI --> GATE).
* When the pad or D-BEAM TriggerMode is set to “GATE,” note o is transmitted when
the pad is released or the user’s hand is removed from the D-BEAM.
* When the D-BEAM TriggerMode is set to “GATE,” note o is transmitted before note
on when the pad is tapped while being pressed down.
Note On
Status 2nd byte 3rd byte
9nH kkH vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = note number: 00H–7FH (0–127)
vv = note on velocity: 01H–7FH (1–127)
* Transmitted the note numbers which are specied by the kit.
* This is transmitted when the pad/external pad is tapped or the D-BEAM/hi-hat
control pedal is used.
Polyphonic key pressure
Status 2nd byte 3rd byte
AnH kkH vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = note number: 00H–7FH (0–127)
vv = key pressure: 00H–7FH (0–127)
* Transmitted using the note number set for the pad when the pad is pressed.
* When the rim of a pad connected to TRIG IN is pressed, 7FH is transmitted using
the note number set for the pad; 00H is transmitted when the rim is released (when
using a pad compatible with choking).
* Not transmitted when Pressure Tx (MENU --> SYS --> MIDI --> MIDI) is set to “OFF.”
