hello miquel,

here are just two basic ideas, use these as
a start for your own experiments:

to create new waveforms you can mix the standard waveforms
of a vco together with different polarities, or feed the
mix of these waveforms back to an input of the same vco.

to create new filter responses you can mix the output of
a filter with the inverted unfiltered signal.
for example if you do this with a lowpass filter,
you will get a highpass response at the a138c output.

best wishes
