[sdiy] opto LFO

[Peter Blackett]

Hi,
just a quick comment that if you do sue an LDR then they will be a
slight delay as you change from one speed to another ,as from what I've
been told the resistance of the LDR doesn't change instantaneously.
but this does simulate the behavour of the rotary Speaker effect units
[Leslie speakers ] when they change from a slow rotation speed to fast .
[ or from fast to slow ].
more info on Leslie speakers at http://www.captain-foldback.com
details of one  other instrument that use light sources and
photodetectors ,the photosonic instrument
