Yeah the Kronos absolutely does wavetable stuff with the wave sequencer aspect of HD-1. It's difficult to approximate the programming of something as sophisticated as say, Codex, but it is possible nonetheless. I've cross programmed sounds from Codex into the K without a hitch.

Unfortunately the entirety of the signal is passed through the digital effects which does make the sound essentially digital. Aliasing occurs when a high pitched frequency (usually an overtone) breaks the Nyquist limit and appears as an "alias" at a lower register. So when the analog signal is digitized it could create such artifacts.
Naturally Korg has very good anti-aliasing tech and will have a proper hidden filter before the ADC. I'm crossing my fingers for a "true bypass" routing on the hardware level but it seems unlikely.

I would like to see the result ( Programs/Combis using Al-1/Mod7) of sophisticated and/or deeper programming of Kronos.

couldn't Kronos, with a knowledgeable sound designer, approximate many of the sound characteristics of Prologue ?

That's a good question.
Just one point about that, one example as regards the VCF Cutoff parameter. On a real analog synth, of course, it's a no-step setting. On the Prologue, as the cutoff is digitally controlled, it's a 1024 steps setting.

As the Kronos cutoff is controlled by a 128 steps setting, some could say Kronos is far from a true analog synth.
Not so sure, because there are the AMS MIXERS, with "Smoothing" setting, you can apply as a modulator to the cutoff frequency. That way you don't hear steps in modulation anymore. This is a really powerfull characteristic.

It was just a very little example.

So I'm quite sure it would be possible to get near of a Prologue synth with the Kronos, (as many other analog synths, by the way).

Thanks for that. I realize there are going to be ' control differences', different filters, difference in routing.

I was curious if both boards had numerous similarities in underlying architecture- which could result a similar result, given a talented sound programmer.

Even, after 7 yrs of popularity, I don't see where Kronos has been thoroughly
exploited, as in expertly programmed with the Al-1/Mod7 engines + wave sequencing.

Korg had the talent in house, as we can see. I am not aware of a similar bunch of deep programming talent.

Great discussion here. :)

Ah, you've tried it out then! Good stuff. Yeah, crossfading is of course not the same as interpolation, but I would think for a good subset of wavetable type patches, the difference would be more semantic than audible.

I was originally thinking that the wave sequencing was a completely separate offline process, but it looks like you can turn 'run' off, and then AMS modulate position - so maybe control the "wavetable index" with an EG or LFO. Definitely need to spend some time exploring this. Looks awesome!

Have you seen Synthesis Technology WaveEdit? It's a nice piece of software for creating custom wave tables. They built it to create wave tables for their E352 and E370 [Eurorack] modules, but they generously made it free/open source. Might make for some real fun in the wave sequencer.

Do you think there's some kind of smoothing algorithm on the filter without even running it through the AMS Mixer smooth function? If I go to an init AL-1 patch, go into RT control mode and crank up resonance (knob 2) and sweep cutoff (knob 1), I don't really hear a zippering/stairstep effect.

Couldn't agree more. Good gravy, MOD-7 is such a monster synth architecture. You could probably spend a lifetime making new patches and never run out of possibilities.

I'm definitely looking forward to going deep into the K's synth engines. Happy to share any successes here. Would love to get some new 'buzz' going here despite the K being 7 years old. Hope I'm not being naive, but I think there's tons of new territory left.

You could say that the Kronos covers everything but having a dedicated Analogue machine, is like having the ultimate crossover/hybrid synth. The JDXA does this quite well and enjoyed owning it but the Kronos/Prologue combo is simply huge to my eyes and ears.
Midi layering them can take you to some real goose bump places and sequencing it with the Kronos is going to be awesome.

I think they will be an awesome pair. Looking forward to hearing about it.

Hope I didn't inadvertently side track this post into 'where there's overlap'. I'm just an excited new Kronos owner. :)

Even if the K could theoretically reproduce every sound the Prologue can make, in practice, I think the Prologue is going to lead to very different sonic territory just by nature of the design. The combo definitely piques my interest!

Well, I don't think so but you're right : I can't say I hear some step without AMS Mixer Smoothing.

All in all, I'm quite sure the Prologue won't bring sounds the Kronos would be unable to play. But I could be wrong, of course.

Well you bought the right one first. :D

You won't be needing a Prologue anytime soon. The Kronos is 'the' beast.
The Prologue a supporting act for us owners that have had the Kronos for some years.
There will be overlap in some areas but I'm hoping to programme bespoke Analogue stuff, twiddling knobs. The Kronos is always going to be the foundation of my playing.

I have to use HD-1 when it comes to Wave Sequencing. I'll post a new thread with further details.

That's exactly correct. In fact, the difference between wavetable, granular, and wave sequencing are all more or less semantic.

Right again. I'm surprised you were able to understand that much without trying it first hand!

I have not seen that. VERY powerful. And yes, very useful for creating waveforms to load into a Wave Sequence. Never heard of the term 'posterization' for bit reduction but I'll take it. I guess it's a common term for visual effects but the same math applies to audio.
WOW in video #2 when he's applying varying amounts of transformations to each waveform in the table... That shouldn't be free. That's amazing.
Between what that can do, and what HALion6 can do... the future of wavetable and additive resynthesis is very bright.

There's definitely an interpolation algorithm. Fun fact, the MMT engine tunes each position of it's 8bit filter steps to chromatic notes. Always thought that was neat. The Kronos does not behave the same way though.

Charles, I think its great you are wrapping your brain around Mod-7.

I don't have the skill or patience but know how important it is that we see
something significant from Mod-7. I also think it might be a business opportunity since creative musicians are always considering new expensive synths.

Since Kronos has a loyal user base, it would seem to follow, that many of us would greatly benefit from further development of Mod-7

I think the Kronos is the best thing since, well, everything! Having just seen the Who last night here in Toronto and getting to watch Loren Gold play his K88 on the screen and just HEARING the sheer beauty of his piano sound, well it brought tears to my Wife's eyes!

My thing is, I really need to get a good handle on the step sequencer. Among many many other things.
