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;

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:

• Dual-MIDI-Interface.ino

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