M.P.W.A. built

[Bill Felton]

All I can say is
YES YES YES YES YES!!!!!
This is one wonderful module!
All of you who are building should have
at least one of these [and,btw, look at
the imitation of it on the JP-8000].
Also, I highly recommend these other "oddball"
modules from EN:
The Square-Wave Frequency Division SubOctave Cross
Product Module [what a mouthful]
	simple circuit but 14 pots...  but worh it!!
The 'Timbre Modulator'
	an incredibly simple circuit, which can replace
	a filter if driven by a low-harmonic content wave.
	Brilliant module, easy, I have 4.

Note too that one can take the output of the MPWA
and feed into the TM, or vice versa -- the effects
are amazing, and rated at "bang for the buck",
unbeatable.

Let's see an end to the tired old "vco - vcf - vca"
patch, modified with lfo's and adsrs.  There's
room for LOTS more than that!

Bill F.

"Monster", my hombebuilt analog)

>This takes a sawtooth input wave and feeds it to eight sawtooth phase
shifters, each with its own LFO. Then it mixes them all together.   The
result sounds great - like nine oscillators tuned to the same note but
drifting around.  It's like a sort of chorus effect , but with the eight
LFO's all set at different ( and non-related ) frequencies you cannot
really detect the repetition.  As a result you get a huge sound from a
single sawtooth osc.

when that happens :)
>As for cost, well I used eight TL084's and two TL071's, eight 0.1 caps and
a few resistors.

one resistance value changing each time.
>There is only one value to trim - a 140 K resistor on the schematic which
takes out a glitch in the shifted sawtooth wave.  I used a 100K pot with a
50K resistor on the first block just to find the correct value - this came
out to 143K which I put in circuit and then used for all the other blocks.
