2 x detuned saws PW-modulated[/url]]

.... and that's without unison/unison-detuned, and in mono.

An old example I made showing saws and PW was this:-

Crikey!!

Ive gotta find a synth which does this!

Anyone know which synths or even vstis are capable of Saw Width Modulation?

Correct me if I'm wrong but the MS2000 OSC 1 can do this, It was used for doing hyper/supersaw type of sounds, infact is this not the hypersaw function of the virus?

I know where you are coming from but I will need to look more in to the hypersaw to see which part I'm thinking of, but here's a quote from the MS2000 manual.

Quotenline ms2000b manual

Saw
This is a sawtooth wave, suitable for creating typical analog
synthesizer sounds such as synth bass and synth brass.
• Control1
Adjusting this value will modify the waveform.
A setting of 0 will produce a conventional sawtooth
wave, and a setting of 127 will produce a sawtooth wave
one octave higher.
• Control2
LFO1 is used to apply WFM (wave form modulation) to
the waveform specified by “Control 1.” The “Control 2”
setting specifies the depth of the modulation produced
by LFO1.
By setting the Page 12A: LFO1 “Wave” parameter to
(Tri) and adjusting “Frequency,” you can create the
effect of detuning.

I can't upload the diagram but it looks like the one previous, I never got too far into programming my ms2000, so not sure how good it was.

The Radias will also do this - exactly as you describe for the MS2000. The waveform you would get is exactly as per the diagrams above.

Yes, the Radias can do it too. Seems it's native to Korg VAs.

However, I think Access pinched the idea from this thread and incorporated it into OS v2 of the Virus TI under the "Wavetable PWM Oscillator -
Takes two instances of the same wavetable and phase-shifts them against each other to achieve an effect reminiscent of the traditional pulsewidth modulation of a pulse wave oscillator.", as shown on page 8 of their OS v2 addendum: http://www.infekted.org/virus/files/AddendumOSv2.pdf

Which is exactly as described here.
