I was amazed when I first heard about the existence of the seldom-heard-of Hammond Novachord. First produced in 1938, it's one of the earliest polyphonic sound synths ... 25 years before the first (mono) Moog appeared. https://en.wikipedia.org/wiki/Novachord https://en.wikipedia.org/wiki/Novachord http://novachord.co.uk/ http://novachord.co.uk/ Of course that was in the days before transistors ... and so it used 163 vacuum tubes (and 1000 capacitors). VCAs, bandpass filters, LFOs and on.... Only 1000 were made before the war shut down production; there are only a few dozen left it seems.
