[sdiy] State Variable Filter in AudioXpress

[Paul Perry]

Can anyone say which issue this is in?
I can't tell from the magazine website..
If I knew which issue, I could wait & snag one when it turns up in Australia
in a few months..

(I must say, speaker testing seems a strange application! Doubtless all will
be revealed..)
