[sdiy] What I'm building

I have a three-phase VC-LFO with sine wave outputs.

I made a triple PWM module that runs off a single saw
or triangle, and sums the pulses up.

It is UNDERwhelming.  It looks like a saw, or triangle quantized
to three voltage levels, and varies the width of each pulse.
Occasionally
two pulses line up, and the resulting sound has a distinct 'click' as it
becomes
a two-step waveform.

I'm playing with all nature of logic circuits such as xor gates to try
and get
more interest, but it seems like what I thought would be a dramatic
effect
is really very subtle.

Maybe I need to clock multiple BBDs with this beeatch ???

Any other ideas ?    MUST avoid TV....
