FR-7x V-Accordion
The FR-7x’s sections use the following MIDI channels:
As you see, there are separate channels for the chord
and bass buttons, even though they both belong to the
Bass section. That separation may look distracting at
first, but it actually makes sense. It allows you to use the
bass buttons for controlling an external bass sound,
while the chord buttons could control a piano sound, for
example. If they used the same MIDI channel, the bass
line would have to be played by a piano, or the chords
would be played by a bass sound (unless you own a MIDI
instrument that allows you to program note ranges for
incoming MIDI messages).
Working with a sequencer and other tone
generators
The FR-7x can be used as “input device” for recording
your music. In the case of a keyboard instrument, such a
device is usually called a “master keyboard”.
The FR-7x can be used for two things: to “input” new
parts (i.e. MIDI events) and to play them back.
When you play on the FR-7x’s keyboards, it sends MIDI
data to the FBC-7’s MIDI OUT socket. That socket must
be connected to the sequencer’s MIDI IN port. MIDI data
always go from OUT to IN:
If the FR-7x is used as tone generator for an external
sequencer, you must connect the sequencer’s MIDI OUT
socket to the FBC-7’s MIDI IN port (because MIDI data
always go from OUT to IN).
Though you can also play the FR-7x from another MIDI
instrument, we do not really recommend doing so,
because your V-Accordion has far more versatile perfor-
mance functions than any other MIDI controller avail-
able today: the FR-7x translates all known accordion
techniques and physical effects into MIDI messages to
precisely reproduce the natural behavior of an acoustic
accordion.
If you use the FR-7x as a MIDI controller while recording
a sequence, all actions you perform on the FR-7x
(including the bellows pressure strength) are included in
the recorded part. They can therefore be sent back to
the FR-7x (by the sequencer) – and then, all expression
details are preserved. Be aware, however, that you also
need a versatile sound source (like the FR-7x’s) to use
the recorded MIDI events to their full potential.
Final note regarding sequencers
If you use the FR-7x as MIDI controller for recording
new songs, always ask yourself which MIDI sound source
should play back the part you are recording.
If the FR-7x’s tone generator is not used for the part
you are recording, you need to connect the external
module’s MIDI IN socket to the sequencer’s MIDI OUT
port and activate the sequencer’s “MIDI Soft Thru” func-
tion:
Note that this is only necessary for recording new
material. You do not have to worry about them dur-
ing playback.
