Your FR-7/FR-5 also transmits and receives MIDI data. In this chapter we’ll look at what MIDI is and does and which MIDI 
functions are available on the FR-7/FR-5. 
IMPORTANT REMARK: To take advantage of the FR-7/FR-5’s MIDI functions, you must connect it to the supplied FBC-7, 
because the FR-7/FR-5 itself has no MIDI sockets.
About MIDI
Even though your FR-7/FR-5 is already a remarkably 
flexible instrument (quite unlike any other accordion 
available today), you may also want to use it with other 
MIDI-compatible instruments, sequencers and comput-
ers to record your performances in the same way as 
keyboard players, drummers, guitarists, etc., have been 
doing for a while. 
Another important application for the FR-7/FR-5’s MIDI 
functions is controlling an arranger module that sup-
plies the accompaniment. “Arranger modules” use short 
accompaniment patterns that can be selected in real-
time and whose key depends on the note information 
they receive. You can select those patterns by assigning 
the corresponding MIDI messages to the FBC-7’s foot-
switches (see p. 68), so that you do not have to stand or 
sit next to your arranger module.
Both module types (and all MIDI-compatible sound 
sources) also allow you to use the FR-7/FR-5’s Treble 
and Bass keyboards for playing sounds the FR-7/FR-5 
does not provide.
This is possible thanks to a common language for musi-
cal applications, which is called “Musical Instrument 
Digital Interface
” or “MIDI” for short. MIDI has a lot in 
common with the internet: you can link one or several 
instruments to one another via a cable (but you don’t 
need a telephone line).
You can also use the FR-7/FR-5 as “master keyboard”, 
i.e. an instrument that transmits MIDI messages to a 
device (or software program) that can record MIDI mes-
sages. Such a device or program is called a “sequencer”.
To take advantage of the FR-7/FR-5’s MIDI functions, 
you must connect the FBC-7 as follows:
MIDI OUT: This socket transmits messages describ-
ing actions (such as playing on a keyboard) to the 
MIDI IN jack on the external device. The receiving 
MIDI device executes the incoming MIDI messages 
and plays notes, selects other sounds, etc.
MIDI IN: This socket receives the MIDI messages 
transmitted by an external MIDI device.
MIDI THRU: This socket retransmits the MIDI mes-
sages received via the FBC-7’s MIDI IN port. You can 
connect it to the MIDI IN port of an another MIDI 
device.
Note: The MIDI THRU port does not transmit the MIDI mes-
sages generated by the FR-7/FR-5. Those messages are only 
sent to the FBC-7’s MIDI OUT port.
MIDI can simultaneously transmit and receive messages 
on 16 channels, so that up to 16 instruments (or parts 
of a module or synthesizer) can be controlled. Nowa-
days, most instruments –like your FR-7/FR-5– are mul-
titimbral, which means that they can play several musi-
cal parts with different sounds. This requires the use of 
several MIDI channels. The FR-7/FR-5, for instance, has 
several accordion and orchestral sections that can be 
played simultaneously. They can transmit and receive 
on different channels.
