MIDI Routing

Detailed Description

Operators and utilities for MIDI routing.

Two or more MIDI interfaces can be connected using MIDI Pipes. The simplest pipe just carries messages from the input interface to the output interface, but you can write rules for filtering out certain messages, changing the channel of some messages, etc.

Allows you to use syntax like:

HardwareSerialMIDI_Interface
midiA = Serial1, midiB = Serial2, midiC = Serial3;
MIDI_PipeFactory<3> pipes; // Factory that can produce 3 pipes
midiA >> pipes >> midiB;
midiC >> pipes >> midiB;
midiC << pipes << midiB;
HardwareSerialMIDI_Interface
A class for MIDI interfaces sending and receiving MIDI messages over a Hardware Serial port.
Definition SerialMIDI_Interface.hpp:107
MIDI_PipeFactory
Class that produces multiple MIDI_Pipes.
Definition MIDI_Pipes.hpp:659

Or for bidirectional connections:

HardwareSerialMIDI_Interface
midiA = Serial1, midiB = Serial2, midiC = Serial3;
BidirectionalMIDI_PipeFactory<2> pipes; // Factory that can produce 2 pipes
midiA | pipes | midiB;
midiA | pipes | midiC;

Have a look at the following examples on MIDI routing:

If you're interested how the pipes work, see the documentation for MIDI_Pipe.
