MIDI Informations
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
Data format: BnH 00H vvH
n=channel number:
00H – 0FH (1 – 16)
vv=controller number: 00H – 7FH (0 – 127)
vv=value:
00H – 7FH (0 – 127)
PROGRAM CHANGE
This message selects sounds or programs on the receiving instrument.
The sounds recalled by each Program Change message is described by the General MIDI standard. Usually,
the recalled sounds can be found on a chart included in the User Manual of instruments using this standard.
This message contains the following data:
Program Change : change sound or program;
Program Change Number : the number of sound/program that has to be activated;
Data format: CnH mmH
n=channel number:
00H – 0FH (1 – 16)
mm=Program Change number: 00H – 7FH (0 – 127)
PITCH BEND
This continuous control message bends the instrument's pitch upwards or downwards.
Data format: EnH vvH
n=channel number:
00H – 0FH (1 – 16)
vv=value: 00H – 7FH (0 – 127)
CHANNEL AFTERTOUCH
This message controls the sound according to the pressure on the key. Only one value is transmitted through
the channel; therefore the said value is the same for all notes, and is set by the last key pressed.
Data format: DnH vvH
n=channel number:
00H – 0FH (1 – 16)
vv=value: 00H – 7FH (0 – 127)
NB:
in the Legend ‘70s the Aftertouch message can be transmitted using a foot controller or modulation wheel (see
FC1 ,
FC2 and Mod.Wheel Dest parameters in the EDIT / COMMON section).
SYSTEM MESSAGES
ACTIVE SENSING
Active Sensing is a type of MIDI message used to prevent unexpected results in the event that a MIDI cable is
disconnected or damaged while the instrument is being played. Upon the receipt of an Active Sensing message,
the stage piano will begin to monitor the status of connected MIDI cables. If no MIDI data is received over the
next 300 ms, the
Legend ‘70s
will conclude that a problem has occurred with a MIDI cable, and in response, it
turns off all notes.
TIMING CLOCK
Timing Clock messages are transmitted at a fixed interval (i.e., 24 times per 1/4 note) to synchronize connected
MIDI instruments. Use the
Master Clock parameter in the EDIT / COMMON section to specify whether the
instrument’s internal clock or Timing Clock messages received via the MIDI [IN] terminal should be used for
synchronization.
