Midi input device.
This is the base class for user defined MIDI input devices.
Child classes of MPxMidiInputDevice should define:
- a constructor which defines number of buttons and axes
- nameAttributes() which names the buttons and axes (optional)
- deviceState() which turns a midi event into an MDeviceState or returns NULL if it is not a midi event from this device
- Examples:
-
jlcVcrDevice.cpp.
