The biggest Theremin forum in English language, operated by Jason Barile and John Hoge, with my support as a technical redactor.

The actual discussion threads are unfortunately not very interesting for the grand public since they are dominated by “engineers” and technicians” who discuss their abstruse theories which are often far away from the reality, without any proof that they master the subject in practice. None of them has actually built a working instrument which is considered by professional players as playable and seen as a real improvement compared to existing instruments.
