Detuning / filter variation per voice like OP-X-ProII

[Annabanna]

With an army of synth vsti's, I end up using OP-X-ProII on nearly every track despite it having on of the worst interfaces of any synth I own. The reason is that every time I A/B the results, it just sounds better.

Not only is it anti-intuitive, an just a mess of features awkwardly piggy backing on the most outdated UI possible, but it's severely limited in it's waveform selection, and missing some key features.

The secret sauce seems to be in the particular way in which it does slight variations per voice in filter shape, tuning, ADSR. Try as I might with something like Serum, the sort of automated approach to detuning and the like just doesn't give the same results.

It occurs to me that MPowerSynth or MSoundFactory might be able to do all the same things, but before I go down that rabbit hole, I thought I'd ask around if there are particular issues, tips, or tricks I should be aware of.

Basically looking for lush 80's sounds with analog character (drift, detuning, etc).

For instance, are there specific ways to (or not to) do this because of CPU spikes or other issues with either of these options? Settings I may need to change to avoid issues? One better for this purpose for any specific reason?

FWIW, I don't usually end up using all 6 voices in unison. More like 2 or 3, but then the way OP-X-ProII cycles through them really helps to differentiate the sound.

Try MSoundFactory. On the global tab there is an analog panel (top right) that creates randomness to all modulators, filters, OSCs and more. You can then go in and finetune each to taste or even add new ones, but the default usually works really well.

Same with TheWaveWarden Odin2.There you can use the modulator called "Unison Index" to modulate any parameter of each Unison Voice individually. So for Voice 1 the Index has value -1 for Voice n it has +1.
After playing around with Odin2 and becoming enthusiastic about the feature, I've created this MSoundFactory Feature Request: viewtopic.php?p=7798347#p7798347
Bottom Line of the discussion: A "Unison Index" the same way as in Odin2 won't be possible in MSF.

That leaves you to the analog dials as jmg8 has already said.
Additionaly you can use the per-voice random modulators like "Note Random 1/2". But you cannot exactly control unisono voices individually but only the whole oscillator.

"But you cannot exactly control unisono voices individually but only the whole oscillator."

If you place the OSC into a unison module and set the number of unsion voices there (as opposed to inside the OSC) you can now modualte each unison voice independently. There are 3 mod sources that work here:
1. Sequence. This creates a different fixed value for each voice and is the same every time you press a key.
2. True Random. This will create a different random value for each voice eveytime you press a key.
3. Random. Same as true random, but will also randomly modulate while the key is held.

I can try to make a video on this. I did something similar before, but I'll try to go more in depth and show 2 ways to do it if possible. No promises though.

Showing a number of options to achieve the same end in one tutorial along with discussion of any settings or system resource considerations would be quite helpful. The stereotypical example of detuning and filter variation fatness would seem to be that old Oberheim "brass" type sound because it's not just the detuning, but it's obvious filter ADSR with a slow attack highlights the filter variations per voice as well.
