M.P.W.A. built

[Joe Farler]

I just built the Multi-Phase Waveform Animator from the Electronotes Preferred Circuit Collection.  

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.
It's fairly easy to build - mine worked first time - don't you love it when that happens :)
As for cost, well I used eight TL084's and two TL071's, eight 0.1 caps and a few resistors.
There are no controls and only an input and an output.
Complexity is low - one circuit block is repeated eight times with only 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.  
So those of you with the PCC, I would recommend this circuit as easy to build and good sounding.
