MOTM

The responses have been VERY interesting and
insightful.  But they really didn't answer my
question.

What is the relationship (if any) between the pipe
lengths marked on a synthesizer and the frequency
output.  The frequencies mentioned in the replies seem
too low for what I hear on my synths.

That did me think of the psychoacoustics of pipe
organs.  I don't think a lot of churches can
accomodate or afford the largest pipes.  So I have
seen 3 things done to accomodate this:

1.  Lay the pipe sideways on the floor.

2.  Use a synthesized tone with a large subwoofer.

3.  Use an implied tone.  Off the top of my head, I
can't remember exactly how this is achieved.  But this
is the most interesting IMO.

This also brings up the topic of resonant frequencies
of different spaces.  Of of my favorite techniques
when perform is to tune my kick (TR-909) to the
resonant frequency of the performance.  You want to
talk about a hell of a kick.  People can't figure out
how I am doing it.  I have seen a couple of other
performers also use this technique.  Most of my
current work does not have any kicks in it
unfortunately.  I have NOT tried pre-tuning my synths
to the resosant frequency yet.  Has anyone else tried
this?  I think the cool thing is that it comes in
resonating as opposed to tuning it manually during the
performance.  Shake the rafters!  I guess there is the
potential of literally bringing the roof down with a
sufficiently strong sound system and a sufficiently
weak roof.

Mind Your Bass Bins Mate!
