Preventing the transmission of certain MIDI
messages
(12.5 Global Filters)
The parameters on this page allow you to filter all or
some MIDI messages each section can transmit (see
"MIDI parameters for the various sections/parts" on
p. 113).
Use these settings if the receiving MIDI device poses
problems whenever the FR-7x transmits a given MIDI
message.
Note: This parameter applies to the FR-7x as a whole (all Sets).
(1) While the main page is displayed, press and hold
the [EXIT÷JUMP] button.
(2) Press register [12] to specify the function group.
(3) Press register [5] to select the following page:
(4) Press the [DATA÷ENTER] knob to select the
"PARAM" parameter.
(5) Rotate the [DATA÷ENTER] knob to select the param-
eter whose setting you want to change.
The available options are: Note Tx, CC00, CC32, PC,
AftTouch, Volume, Panpot, Reverb, Chorus (see
p. 113).
(6) Press the [DATA÷ENTER] knob again to select the
"VALUE" parameter.
(7) Rotate the [DATA÷ENTER] knob to select "Tx Off"
(don't transmit this MIDI message) or "Default" (as
specified for the "MIDI TX" parameter of the regis-
ter in question.
(8) Press the [DATA÷ENTER] knob again to confirm your
selection.
(9) Repeat steps (4)~(8) as necessary.
(10) See page 103 if you want to save these settings.
If you don't save them, they are reset when you
switch off the FR-7x.
Preventing the transmission of certain MIDI messages (Advanced)
Sending program change messages
(Send PC & 12.6 Bank for 'Send PC')
Though each register can transmit a program change/
bank select cluster when pressed (see "CC00, CC32, PC"
on p. 114), you can also transmit sound select messages
on the fly – without changing registers on the FR-7x.
These are MIDI messages that cause an external instru-
ment or device to select a different memory (i.e. another
sound or effect).
This functionality is mainly intended for selecting set-
ting groups of various sounds on external instruments.
Such setting groups may be called "Performances" or
"Multis", which you may want to select while playing,
because working with "finished" Performances, etc.,
does away with the need to program sound select
addresses for the FR-7x's registers (see "CC00, CC32, PC"
on page 114).
This function transmits messages to an external device
whose MIDI IN port is connected to the FBC-7's MIDI
OUT socket.
Here is how to take advantage of that function:
Defining the 'PC' format
Despite the function's name ("Send PC"), the value you
enter on that page is not really a program change num-
ber, but rather the memory number used by the receiv-
ing device.
"502" (for example) therefore refers to Performance
number 502 of the receiver, but that number cannot be
conveyed as such via MIDI.
The MIDI standard provides only 128 program change
numbers (for selecting memories) and two messages
called "Bank Select" that allow you to select 128 banks
each. Two bank addresses ("MSB" and "LSB") with 128
possibilities each, plus 128 Program Change numbers
provide 128 x 128 x 128 values= 2,097,152 possible
memories.
The numbers you enter on the "Send PC" page should
therefore be taken to mean "memory XX of the receiving
device". How does the FR-7x convert it to a MIDI address
that conform to the CC00/CC32/PC format (each of
which supports a maximum of 128 possibilities)? Enter
the following parameter:
