Quick pulse-width question

[Timo]

Forgot to upload this one:

[2 x detuned saw-oscillators with/without PW]

...Which shows the difference between: a) two x detuned saw oscillators with pulse-width modulation, and then b) without the PW modulation.

Both in mono, and no unison used. Definitely livelier and fatter. w00t. Even beats Hypersaw.

I reckon the JP8000 uses some form of PW for at least a few of the individual saws that make up the supersaw. You don't need to modulate PW via LFO like I did in the examples above, instead you can have individual saws at various static pulse-widths so there's no 'movement' but it's still phat (but not 'overwhelming', like what would happen when doubling up on unison).

My Z1-card unfortunately only has two main oscillators, but imagine three oscillators with individual PWs! Or seven, like the supersaw.

but timo thats not really modifying the pulse width of the saw...there is no real width to a saw just what is givin by freq...those instruments might use it as a pseudo name but that looks more like 2 saw waves synced rather then a width modulation...

well blank i think it is not a classic sync function as we know it in the virus, there is a parameter you can change which is not available in the virus sync function, look at the waveforms, they all look like synced saws but with some variations, so i guess it is a customizable sync function

what about using an lfo to modulate the sync?

It's still synced saw.

yeah...

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.
