+# group `midi_device` {#group__midi__device}
+
+You use the functions when you are implementing your own midi device.
+
+You set a send function to actually send bytes via your device, this method is called when you call a send function with this device, for instance midi_send_cc
+
+You use the midi_device_input to process input data from the device and pass it through the device's associated callbacks.
+
+You use the midi_device_set_pre_input_process_func if you want to have a function called at the beginning of the device's process function, generally to poll for input and pass that into midi_device_input
