Leslie simulator, was PAIA and ARIES

[harry]

Hi all:

The Leslie Effect Simulator is going to be a big disappointment if you are
expecting a... (er....) Leslie Effect Simulator.

Its a single BPF driven by an LFO. Don't recall if it is summed out of phase
to
make a notch... (we'll know soon right... ;^)

A phase shifter, or better yet two phase shifters, with separate LFO's would

be a better deal.

OTOH its a simple circuit. And I bet it is very cool sounding for what it
is...

OTOOH: It isn't a "Leslie Simulator" by today's standards.

Yippee !!! It does NOT use any BBDs   ;^)
