There is, indeed. Wanna join? (;-) We do have a few members in Oz.
In spite of my abysmal ignorance, I still find that I have knowledge to
pass on that people find helpful. But a lot of what I do for the
Institute is managerial.

I haven't noticed one in the local municipal hall. There's an old
Millbank amplifier, a couple of loudspeakers and two microphones. There
are *millions* of rigs like that, compared with the thousands that are
as you describe.

Have you got that the right way round? I thought that pitch shift was
not helpful in a live sound system?

Yes., I've occasionally repaired some geetar stuff (under protest). I
know that if it can be done, someone will make a box that does it, even
if it really *shouldn't* be done in public. (;-)
