MidiDjConsole.ProfileDisplayMidiCommandSet method

Previous pageReturn to chapter overviewNext page

Remarks

 

Sets parameters of the short MIDI command specific for a VFD display control item stored inside the profile. Current parameters of the short MIDI command can be obtained through the MidiDjConsole.ProfileDisplayMidiCommandGet method.

 

The short MIDI command is composed of 2 bytes combining 3 elements:

 

One byte composed by the code of the MIDI Command, typically a "Control change" (hex B0) on the more significant 4 bits and by the MIDI channel on the less significant 4 bits.
One byte of MIDI "Data", usually indicated as "Data1", representing the code of the physical display control.

 

Data to display on the VFD display element are sent through the second byte of MIDI data, usually indicated as "Data2", and can be sent through the MidiDjConsole.ProfileDisplayDataSet method.

 

The combination of MIDI command parameters is usually defined inside the technical specifications of the physical DJ Console and may vary a lot depending upon the DJ Console in use.

 

For further details about interfacing with MIDI DJ Consoles see the MidiDjConsole object section and the How to manage MIDI DJ consoles tutorial.
