Detailed description

No detailed description exists yet for this component

Examples

Basic example to play a series of notes getting higher in pitch and then going down in pitch. This repeats in a loop and each time the loop repeats the instrument is changed. The current note and instrument are displayed on the LCD. FC6 Icon.png MIDI Test File MidiDemoRun.jpg


The MIDI component during simulation has functionality to allow it to work with MIDI synthesizers installed on your PC.

To select your software or hardware synthesizer select from the property selector.

MidiSim.jpg


If you don't have a MIDI interface installed then IP MIDI seems to be a good option that works well.

Once installed the MIDI output should play through your computer speakers.


The console window can be used to view the MIDI data as it is sent out and received.

The MIDI component during embedded operation will communicate using a UART serial channel. An EB021 MIDI E-block is available to allow standard MIDI cables to be connected up to a system.
