[sdiy] 60s organ sound

[Ken Stone]

Adding to this, a lot of them used pseudo sawtooth waves too, either by
charging caps from the square waves, or by making stair-cases by mixing a
few octave separated saves together.

My suggestion - feed the oscillator into a sub octave generator with at
least 3 sub octaves, and mix the sub-octaves to taste, then feed the result
into a fixed formant filter (or a VCF that is not under voltage control).

Of course, this is a much simplified arrangement, but it will be a good
starting point.

Hammonds start with sines, but most importantly, their harmonics are false -
taken from the nearest existing frequency to the desired harmonic. Forget
about simple emulation of this - it never sounds right.
