Thanks to a great contribution by theremin engineer Thierry Frenkel all OpenTheremin V3 can now be software updated to High Definition Audio with 16 bit dynamic volume control.

He notes: I played through my entire repertoire for two hours last night and couldn’t stop. As if it were a completely new instrument.

Thank you Thierry.
