You have cut to the core in this post! There are indeed two different applied meanings for 'anaog logic or analogic. One which is truly digital-aka binary- 'underneath' analog inputs and often outputs too. The other is what you had in mind based on your post here. More akin to the fuzzy logic you mention in the next paragraph. They are truly different things and the results are different too. But fortunately they may be combined for even greater effect than used singly.Dolphinwolf wrote: ↑Wed Sep 22, 2021 10:50 amWhen I started this thread I had a preconception that was not communicated well. Min and Max were all that I considered to be analog logic. Now I understand that some people consider this term to be a misnomer and other modules are important to this concept like comparators and slew and such.
You'll need a NOT aka inversion too. <--One reason I try to champion making and using moog style V-trig to S-trig patchcords. Add a couple diode patchcords I also regularly champoin and you have the means for both analog and binary logic.Here is the gist of my concern and curiosity. If Min and Max are functional generalizations of And and Or gates then why the hell are we not able to stack and combine these analog gates to extract all kinds of significance from musical signals?
Sure. Serge T also recognized what you've typed here about the massive utility of functional AND and OR and agreed! That's why there's a peak and trough module in his systems. Those are simple circuits. Why not make up a bunch of them and see where it leads? that may give you more and quicker answers than we could share here.This thing I am typing on uses a whole bunch of boolean gates to do all kinds of things, wouldn’t it stand to reason that combining analog gates could yield enormous profit?
Yes. This would be a useful path, I think. I would expect that looking into NLC's range of modules will also bear *much* fruit. Probably no one has ever done as deep a dive into this arena -for synths- as he.I think I just need to research fuzzy logic and see if it can be applied to music processing equipment.
The ARP2500 is the queen of this. The matrixswitch patching sets up all kinds of inherent non-linear mixing, aka analogic. While you can patch it in a style of a 'patchcord' subtractive synth, there is much to be found going outside that approach! In your own synths, stop relying on the -mostly!*- outdated advice to avoid patching outputs-to-outputs and your world of sounds grows widely and immediately.Also patching things into other things with only the smell of rationality hovering above my head.
*It was mostly an outdated understanding of the electronics needs -that OPAs would be broken by this**- and the Serge module owners manuals that started this now-held-as-sacred advice. But it doesn't hold up in actiual practice outside Serge. And some Buchla too. Some early 'digital' like the circuits of the EDP Wasp. Be careful with modules based on those ancestors. But in the large, almost all other synth modules handle output-to-output patching just fine. Alan Strange was talking about it way back when his book was published, ARP was doing it with both the 2500 and 2600 patching examples and advice. Not patching passive mults freely -to avoid some inherent 'danger'- is some of the most limiting and 'stupid' advice that ever rose to supposed fact in the modern synth world.
**Besides opamps which *did* need care to prevent various problems. In the 60s. There was also the *huge* growth of TTL logic in the early 70s and especially its 'totem-pole' output structure which fed this fear of putting outputs together. Because if you do that in TTL, the outputs DO try to fight each other and that *can* lead to high current draw, heat and failure. But that doesn't really apply to most synth circuits. By the early 70s, the op amps used in synths were mostly protected and the fear of output to output no longer was based on much truth.
This 'analogic' ground was well plowed and seeded in the past, with a bountiful classic harvest of music and other results that led to some of the lust we see today for clones. But then became overgrown and thick with unruly brush in the fear brought on by the first wave of digital and the fresh memories for opamps of the elders.
It has lain fallow too long! Take up your plows and hoes! The ground is rich and with tender care it will repay and not forget evermore.
