Is DIVA the end of the road?

Our current favourites are the Polivoks filter, a Steiner-Parker filter and a diode ladder (TB, System 100)

Steiner-Parker à la Synthacon ? Please ?

Damn, now I want them three. Diva beggs for some more unpredictable/wilder components : Bite feels lonely

TB's enveloppes could be great too !

[EvilDragon]

Polivoks filter in Diva would be a MUCH better choice than TB-303!

I'd still really love a little Pro One magic. It's the only vintage synth I GAS for at all.

Yep, our recently refurbished one is a really cool sounding machine.

One thing I remember people saying about the Minibrute is that the resonance is extremely unstable and chaotic at high levels. Think there'd be a way to employ digital trickery to control the resonance of a Steiner-Parker, via a knob or slider? Or do you think that chaotic resonance is part of the charm?

Chaotic resonance is a part of S-P filter's charm.

Hmmm, they are not much different from MS-20 filters. Structurally there's two or three more resistors, which allow for multiple inputs (BP/LP/HP) at once. Not sure how they're realised in the Minibrute, but the original ones have some sort of symmetric approach that makes them look more complicated than they are.

Our intern (who's currently all over the Polivoks) might wnat to have a look at those.

I suppose it just goes back to my interest in the idea that digital emulation of analogue circuit behaviour could allow things that are difficult or impossible in the real world.

I'm extremely intrigued by the idea that there might be synth designs that were never realised, because the circuits were too large or complex; component values had to be ridiculously exact; or the design would only work at a specific temperature. But I'm not really educated enough on the subject to be anything more than enthusiastic about it.

Something like an analog Comb filter could be interesting:

So far i only used digital Comb filters like that in the Waldorf Synths (e.g. Blofeld, Largo).

An interesting filter could also be an analog formant filter based on e.g. multiple resonant BP filters:

I had done a comparable approach in MuTools MUX with a bunch of BPFs at fixed frequencies which were close to certain "vowel" frequencies:

There also was the Moog 914 filter bank (1 LPF, 12 fixed BPFs, 1 HPF) for the Moog Modular:

Audio Damage made this emulation:

There also seemed to be a smaller 907 module (with 8 fixed BPFs), this is a DIY version:

Not sure… any noise we'd add would be kind of fake.

It's one of those things that we found not-so-desirable to model.

There used to be noise sources in the vintage age that were more prominent: Tape noise, cables, cheap consoles. It makes more sense IMHO to add those than to add noise into the synth itself.

We did consider scratchy knobs as a means of copy protection though

I've been experimenting a bit with Satin of late. It is soooo good. It satisfies my craving for noise. It works great in combination with Diva. There is also a subtle warming type effect that I get from it. Great job!

From my experience with the Minibrute, the SP-filter's resonance almost sounds like it's being modulated by noise when you set it to high levels. This is intereting because with smaller resonance, you don't get that sound, but instead a slurpy, shallow resonance that reminds me of the SID chip's filter.

You can sort of emulate this in Diva by using the Bite filter and adding noise modulation to the cutoff and/or the resonance to taste.

I purposely avoid dedicated hardware-software combos. I have done so ever since NI abandoned Kore. I have Maschine, too, which I bought into before Kore was abandoned and was all rah-rah about the combo, but I just totally soured on it when Kore was dropped, especially when links to my Kore sounds were made to go away from NI's we've site (to be fair support sent me links right away when I complained and now I can see them in the NI service center so they fixed the issue). I have not yet upgraded to Maschine 2 and don't know if I will ever do so.

There are plenty of advances to be had in software synths. The human-computer interface is one of them.
