Program Change; Control Change - Viscount Cantorum VI Plus Mode D'emploi

User Manual

PROGRAM CHANGE

This message is used to select the programs or sounds of the receiver instrument.
There is also a specific standard called General MIDI which describes which sound should be recalled for
each Program Change received. This association is usually described by means of a table included in the
user manual of the instrument which adopts the standard.
This message contains the following information:
Program Change: voice or program change;
Program Change Number: the number of the program or voice to be activated;

CONTROL CHANGE

These are control messages (often associated to trimmers or pedals) used to add expression to the
performance, allowing you to set (and control in real time if necessary) voice parameters such as volume
(CC n.7) or the position of the swell pedals (CC n.11), etc.
This message contains the following information:
Control Change: a controller has been adjusted
Controller Number: which controller has been adjusted
Controller Position: the position of the controller
SYSTEM MESSAGES
SYSTEM EXCLUSIVE
These messages can only be interpreted by an instrument made by the same producer as the transmitter
device (in some cases only by the same model). They mainly relate to the instrument's sound generation
and programming parameters. The organ uses these messages to control all the internal parameters and for
switching the voices on and off.
REAL TIME
These messages are used for the real-time control of specific modules or functions of a connected
instrument. These messages include the Start, Stop, Pause/Continue and Clock commands.
START: the sequencer has started to record or play back a MIDI sequence
STOP: the sequencer has been stopped
PAUSE / CONTINUE: the sequencer has been set in stop status
CLOCK: the sequencer speed
N.B.
The organ does not transmit / receive the messages described above. They are described for your information only.
The Real Time messages also include the Active Sensing code, sent to keep the dialogue between two
MIDI instruments alive. When the receiver instrument does not receive any MIDI data or the Active
Sensing code in a time interval of about 300 milliseconds, it considers the MIDI connection to have been
deactivated, so it switches off any notes still active. Remember that the transmission and reception of this
message is optional, so not all instruments are equipped to handle it.
