Pitch Bend Range choice is also extended (Allows 4 octaves Bend)
MIDI CC from Pitch antenna (Rod) have 14 Bit resolution when applicable. Example of application: you can create a software synth controled by CC7 for volume and CC16 (MSB) - CC48 (LSB) for pitch without using Note On/Off and Pitch Bend messages.
Urs also made a very clear presentation of the MIDI feature on his website: http://www.gaudi.ch/OpenTheremin/index.php?option=com_content&view=article&id=200&Itemid=121, many thanks !
