v1.9.0
There was a mismatch between the factory and filter function naming for some of the MIDI 2 Channel Voice Messages (e.g. make_registered_controller_message() vs. is_midi2_registered_controller_message(). midi has been removed from those filter function names (e.g. is_registered_controller_message()) , the midi versions are now deprecated.
Also introduced is_registered_per_note_controller_pitch_message() and convenience conversions between controller_value and pitch_7_25. These changes should improve readability of the code.
