could triangle be affected by the pulse width modifier?

TO= triangle output
2TO= double triangle out
As the triangle is derived from the sawtooth by a rectifing process,
it goes only positive (0 to 1).
Don't know how the doule triangle is output , though.
The sine is obtained by slewing the triangle tips, so as you hear you
get a very good sine, though not a perfect one.

PS(and OT): I'm looking for infos about the roland VP330, or at least
a good scan of the ensemble's diagram. any help?

wave shape converter....IC9 IG00158

I believe

SO is Saw out, PO is Square(pulse) out, SIO is SINE out

What would TO or 2TO be???

Wow. So the solo/monokeyboard is the only one with any touch
sensitivity.

Definitely send us pictures! I love how they mount the EG level
sliders vertically and the EG time sliders horizontally.

Following up on this, I looked at the voice-card parameters from the
tone board and compared it to the CS80. I put a picture here:

It looks like the GX1 adds a triangle wave and static filtered
versions of thesquare and sawtooth waves. There's also apolarity
switch on the VCF EG output. It looks like it's missing the sine wave
bypassing the VCFs (which I think is really useful). It also looks
like the touch response settings are missing, which make sense given
the previous info from Niklas. I'm also not sure if each voice has
it's own PWM oscillator.

How do people who have used both instruments think these differences
affect the sound? I also remember Crow's analysis and recreation of
the VCFs in both and that they sounded different from each other. How
close can a CS80 come to sounding like a GX1? What about stuff other
than the voice cards? Ring-mod? Sub Oscillators? Other controls?
