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.

System Realtime Messages
Active Sensing
When Active Sensing is received, the FR-3 starts monitoring the intervals of all fur-
ther 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-3 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-3 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.
