Some basic hints and explanation #45

Closed eriveraa closed 5 years ago

eriveraa commented 5 years ago

In this code: output.Send(new byte [] {MidiEvent.NoteOn, 0x40, 0x70}, 0, 3, 0);

what are the channel, pitch and velocity values? (i am new with this library, please help!) THanks.

atsushieno commented 5 years ago

I wrote some example usage on README.md before, there are byte constants in MidiEvent etc.

For more general learning, maybe some web pages like this helps. https://www.wikiaudio.org/midi-channel-messages-tutorial/

(I will close this issue after some quiet days, but feel free to keep shooting usage questions here if any further, I'd be happy to help.)

Thanks, but i still don't get it. In the link mentions that the first byte is status (voice message + channel) and in the example is just MidiEvent.NoteOn, so where is the channel?

Maybe the wikiaudio description is not easy to understand because it uses binary (0 or 1) representation for MIDI status bytes - they say 1001nnnn where nnnn is the channel part. In MIDI 1.0 world, a channel number is 0 to 15, which fits 4 bits. Note On message is 0x90 - 0x9F in C# notation. Does this make better sense?
