I think Paul has a pretty good description on the news page "basically 
a small analog computer" - meaning that with this module you can 
multiply waveforms, divide waveforms, raise to powers or take roots.  
So here is something to think about:

A common "math function" in an analog synthesizer is the VCA where you 
are essentially multiplying an "audio" waveform with a control 
voltage.  Another common operation is a ring modulator where you are 
multiplying two "audio" waveforms.  So you could do things like this 
with an analog computer but, being a "generic" computational unit, you 
can come up with other possibilities:

If you start with a pure tone (sine wave) and raise it to a power, 
harmonics are added to that pure tone.  If you were looking at the 
waveform on an oscilloscope, the higher the power you rise to the more 
"spiky" the sine wave will become.  (It will start to look something 
like a bell curve.)  Alternately, if you were to raise to a fractional 
power (take the root) the sine wave will start to "flatten out" - the 
larger the root, the flatter the tops of the waveform.  (In other 
words, it will start to look like a square wave.)  So in this example, 
you have something of an "un-filter" module - adding harmonics instead 
of removing them.


So Paul - is there an expectation as to cost of this 510 yet?  It 
seems useful - as in it would be cool to have more than one in a 
system :)
