6.2 MIDI functions supported by
the C-180
The C-180 can transmit and receive various MIDI
message types, some of which are straightforward,
while others require some insight into the workings of
the MIDI standard.
MIDI channels used by the C-180
The C-180 uses the following MIDI channels for
sending and receiving MIDI messages:
These channels cannot be changed, so be sure to set
the external device to the channel number of the
desired C-180 part.
Note messages
The C-180 transmits and receives note messages that
translate which keys you pressed on the keyboard.
Program change, bank select messages
In Orchestra mode, pressing a tab to select the desired
sound will cause the C-180 to send two bank numbers
(Bank Select MSB & LSB) as well as a program change
number. When receiving such a cluster, the C-180
selects the corresponding sound. Note that only the
following numbers are recognized. The ones in the
grey box can only be selected via MIDI, and are thus
only received.
Control changes
In Orchestra mode, the C-180 transmits and receives
CC64 messages that describe when the optional SUS-
TAIN footswitch is pressed and released. Furthermore,
the C-180 sends and receives CC11 messages that
describe the movements of the EXPRESSION PEDAL.
Other control changes that the C-180 transmits are
CC07 for the volume (Organ/Orchestral Bass & Lay-
er) and CC91 to communicate the Reverb depth set-
ting (see page 11).
Note: Some of the above MIDI messages are only available
in Orchestra mode. See also the MIDI implementation
chart at the end of this manual.
SysEx messages
The C-180 also transmits SysEx messages that have a
rather complex structure and are thus only meaning-
ful to seasoned MIDI enthusiasts. If you work with
the internal Recorder or an external sequencer, it may,
however, be possible to record them without even
knowing what they look like. See your sequencer’s
manual for details.
If the sequencer does accept SysEx messages, you can
also record the settings of the BASS and MANUAL
tabs as well as of the temperament in Organ mode,
and transmit these registration data back to the C-180
for realtime automation.
SysEx messages sent and received when the tilt tabs
are operated in Organ mode:
These data are followed by the SysEx body comprised
of a Sub-Command byte, an optional Offset byte, 34
data bytes, the Checksum and “F7” (End of exclusive).
The Checksum value can be calculated using the for-
mula [128 – (Offset byte + data bytes)].
The data bytes respresent the new state of the bitmap.
The registers (tilt tabs) are assigned to the values listed
below.
