1. Received data
■ Channel Voice Messages
● Note off
● Note on
● Control Change
• The value specified by a Control Change message is not reset by a Program
Change, etc.
❍ Bank Select (Controller number 0, 32)
• Only for Free Bass.
❍ Expression (Controller number 11)
• 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.
❍ Hold 1 (Controller number 64)
❍ Program Change
❍ Channel Pressure
■ System Realtime Messages
❍ Active Sensing
• 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
• 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.
■ System Exclusive Messages
The System Exclusive Messages received by the FR-7/FR-5 are messages related
to Data Set (DT).
● Data Set 1 DT1 (12H)
• 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
each packet must be sent at an interval of about 20ms.
2. Transmitted data
■ Channel Voice Messages
● Note off
● Note on
● Control Change
❍ Bank Select (Controller number 0, 32)
❍ Volume (Controller number 7)
• Volume messages are used to adjust the volume balance of each Part.
