A class that converts byte streams into MIDI messages, and stores them in a FIFO. This is useful if you wish to read MIDI messages via polling instead of interrupts. The class supports every type of MIDI message, and System Realtime messages can be interleaved with regular ones.

Detailed Description
A parser that accepts bytes and outputs MIDI messages.
Example:
#include "mbed.h" #include "MIDIparser.h" MIDIparser myParser; Serial pc(USBTX, USBRX); int main() { while(1) { while(pc.readable()) { myParser.parse(pc.getc()); } while (myParser.available()) { MIDIMessage myMessage = myParser.grab(); pc.printf("%d %d %d %d\n", myMessage.type(), myMessage.channel(), myMessage.key(), myMessage.velocity()); } } }
