■Channel Voice Messages

● Note off

Status	2nd byte	3rd byte
8nH	kkH	vvH
n = MIDI channel number:		0H~FH (Ch.1~16)
kk = note number:		00H~7FH (0~127)
vv = note off velocity:		00H~7FH (0~127)
● Note on
Status	2nd byte	3rd byte
9nH	kkH	vvH
n = MIDI channel number:		0H~FH (Ch.1~16)
kk = note number:		00H~7FH (0~127)
vv = note on velocity:		01H~7FH (1~127)

●Control Change

•The value specified by a Control Change message is not reset by a Program Change, etc.

❍Bank Select (Controller number 0, 32)

Status	2nd byte	3rd byte
BnH	00H	mmH
BnH	20H	llH
n = MIDI channel number:		0H~FH (Ch.1~16)
mm = Bank number MSB:		00H~7FH
ll = Bank number LSB:		00H~7FH

•Only for Free Bass.

❍Expression (Controller number 11)

Status	2nd byte	3rd byte
BnH	0BH	vvH
n = MIDI channel number:		0H~FH (Ch.1~16)
vv = Expression:		00H~7FH (0~127)

•This adjusts the volume of a Part. It can be used independently from Volume (CC07) messages. Expression messages are used for musical expression within a performance, e.g., expression pedal movements, crescendo and decrescendo.

■System Exclusive Messages

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.
dd,...,ee = data:	00H~7FH (0~127)
F7H:	EOX (End Of Exclusive)

The System Exclusive Messages received by the FR-7/FR-5 are messages related to Data Set (DT).

●Data Set 1 DT1 (12H)

10H	Device ID
00H	Model ID #1 (FR-7/FR-5 V-Accordion)
7CH	Model ID #2 (FR-7/FR-5 V-Accordion)
12H	Command ID (DT1)
aaH	Address MSB: upper byte of the starting address of
	the data to be sent
bbH	Address: upper middle byte of the starting address of
	the data to be sent
ccH	Address: lower middle byte of the starting address of
	the data to be sent
ddH	Address LSB: lower byte of the starting address of
	the data to be sent
eeH	Data: the actual data to be sent. Multiple bytes of data
	are transmitted in order starting from the address.

ffH	Data
sum	Checksum
F7H	EOX (End of Exclusive)

•	The amount of data that can be received at one time depends on the type of data,
	and data will be transmitted from the specified starting address and size.
•	Data larger than 256 bytes must be divided into packets of 256 bytes or less, and

■System Realtime Messages

❍Active Sensing Status

FEH

•When Active Sensing is received, the FR-7/FR-5 starts 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 Off, All Notes Off and Reset All Controllers are received, and message interval monitoring will be halted.

❍Start Status

FAH

•When an FA message is received from an external MIDI device such as sequenc- er, the FR-7/FR-5 sends all necessary MIDI information for a song header setup: Treble, Orchestra, Bass/Free, Orchestra Bass, sound setup.

Status	2nd byte	3rd byte

BnH	20H	llH

❍Volume (Controller number 7)

Status	2nd byte	3rd byte
BnH	07H	vvH
n = MIDI channel number:		0H~FH (Ch.1~16)
vv = Volume:		00H~7FH (0~127), Initial value = 64H (100)

•Volume messages are used to adjust the volume balance of each Part.
