Thanks!  Actually, I used my mixer module to construct the hypertriangular
LFO back when I was working on it.  My mixer module has Ken Stone's Analog
Logic circuitry built into it on one of the mixers.  I've never been able to
keep the analog logic nomenclature straight in my mind, so I just refer to
the outputs as 'Peak and Trough', because this is what Ken's circuit does -
it performs the same function as the Serge Peak and Trough function, only in
a different manner.

The module has inverted and non-inverted peak and trough outputs (four
outputs altogether).  On one input, I put in ground as a reference, and the
other input I put the sine LFO wave.  Then I would take the inverted peak
output out (the top half of the sine wave flipped upside down) and the
trough output (the bottom half of the sine wave), offset and mix them
together so that they formed a hypertriangluar output.

As Michael mentions, though, there are a number of ways of doing it.  A
couple of ideal diode circuits  (see Jim Patchell's writings) and a mixer
would also get you one with a sine wave LFO, if you already have one.

Listening to it, that term came to mind.  I was going to name it 'The
Flaser', but a google search returned one hit where someone had used that
term in naming a VST plug-in that did some sort of phasing/flanging thing
'The Flaser'.  So, then I thought "Deep Phase".  Bzzzt again.  So, I just
gave it the hum-drum 'MultiPhase' name.  That didn't return anything music
related.

What is a a 'Flangecho'?  Sounds interesting.  Whatever it is, I'm betting
JH's new project will probably do it =0).

I'm trying to visualize all of the things I would like to put on this
thing - there are so many options.  As usual, it comes down to panel space
determining what actually goes into it.  I would love to put in a dual-line
delay (more along the lines of the Dimension D in this case), because Dim C
really embiggens the sound.

Thanks again - I should make a sample of the Compact A arrangement with 16
stages - that really is a very spacy setup.

My new Web Page is here:

I'm in the same boat as Jim - I can't get to the old site to move or change
things anymore.  So, it just languishes there as the links go cold, one by
one.

Take care,
Scott
