Control Surface master
MIDI Control Surface library for Arduino


This example demonstrates how to group together two or more MIDI interfaces, so you can send the MIDI output over both MIDI USB and 5-pin DIN MIDI, for example. MIDI input is received from all interfaces as well.

Also have a look at the MIDI_Pipes-Routing.ino example, the MIDI Routing module and the MIDI_Pipe documentation for more information about MIDI routing.
Control Surface can be used as both a MIDI sink and a MIDI source.

When you call Control_Surface.begin(), it automatically connects itself to the default MIDI interface (MIDI_Interface::getDefault()).
If you want to route everything manually, you have to connect it before calling Control_Surface.begin(), or you have to disconnect the default pipes before connecting your own, using Control_Surface_::disconnectMIDI_Interfaces().

AVR USB, Nano Every, Due, Teensy 3.x


Connect the left terminal of the potentiometer to ground, and the right one to VCC.

// Create a MIDI pipe factory to connect the MIDI interfaces to Control Surface
// Add some MIDI elements to show that the MIDI interfaces actually work

* The vertical pipe operator (|) is used to make a bidirectional connection
* between a MIDI sink or source and a MIDI pipe.
* You can also use unidirectional pipes. These can be connected using the
* stream operators (<< and >>).
* For example:
* MIDI_PipeFactory<2> pipes;
* ...
* Control_Surface >> pipes >> usbmidi; // Output to usbmidi
* Control_Surface << pipes << serialmidi; // Input from serialmidi
