Another one is to apply a "morph" to the width parameters in your 
function table in your "score".

Or set-up more than one pulse in your score function table and 
morph between them. That should leave you with some controllability.

I morph amplitudes, frequencies and phase relations to minimize
a mechnical aspects and get it to flow a bit more naturally. It
doesn't sound so robotic and mechnised (well, unless I want it to).

There are many viable approaches.  Off the top of my head, I think one
could create a pwm generator out of these ingredients:

phasor
user-defined opcode
setksmps
if then else endif

I'd be happy to elaborate. Not sure if you want the solution, or if
you want to try doing it yourself. The latter is more fun. :)

Best,
Jake

Hi,

Victor hasn't chimed in, but he develop a methd of producing
bandlimited pulses and other waveforms using FM. He wrote an article
about this for AES, the Csound journal and others.

Some more information:
There's an example in QuteCsound showing the difference between
band-limited and non-bandlimited oscillators (with and without
interpolation).

Cheers,
Andrés
