Control Change: these are control messages (often associated to sliders or pedals)
used to add expression to the performance, by allowing definition (and real-time control)
of the timbre parameters, such as the volume (CC n.7) or the amount of reverb (CC
n.66), etc.
As already mentioned, the system messages are independent of the subdivision of the
channels, and once processed, they take effect on the entire system.
There are various types of system messages, including the exclusive system messages
(SYS-EX), meaning those instructions which can only be interpreted by a device identical
to the one which generated them. These messages include the BULK DUMP data, i.e. the
instrument programming instructions. These instructions contain the programming
parameters normally saved in a memory location. They are used to transfer these
parameters from one device to another of the same type, or to save them on a remote
memorisation unit, such as a computer or sequencer, which allows them to be restored if
they are accidentally lost or deleted. Another function of the exclusive system messages
is identification of the transmitter instrument if the receiver device requests this.
7.2 SETTING MIDI FUNCTIONS
As we have seen, after the [UTILITY] button is pressed the display will show:
now select the
[MIDI]
field using the [UTILITY] or [ENTER] buttons; the display will
show the first page of the MIDI section:
In this page, channels (from 1 to 16) can be enabled for transmission of MIDI messages
as output on the MIDI OUT port. The display shows the three sections to which the channel
in question can be assigned:
- Upper
: for events on the upper manual
- Lower
: for events on the lower manual
- Bass
: for events on the BASS section of the lower manual or on the optional
pedalboard.
If the parameter is set with the
**
symbol, the channel will be disabled and it will therefore
be impossible to send the MIDI messages.
Pressing [UTILITY] again displays the second page of the MIDI menu:
