The first softsynth that really sounds like a synth. How did they do it?

In general things keep running. This is why some emulations (EG Softube) will continue to consume resources even when doing nothing. They emulate this aspect. Personally, I feel it’s poor use of resources, and methods should be found to “fake” things (since it’s faking everything else anyway! ;) )

Good to know. Is this true for all analog poly synth hardware? I definitely have some mono synth plugins where they do keep truly free running in the background. Appropriately, a good example is the Korg ARP 2600 plugin.

Well, many things have digital aspects too. So it can vary. But generally analogue means everything is in motion, which can be a plus or a minus depending on what the goal is :)

Synths like the 2600 aren’t fixed architecture. It can have lots of things feeding into other things and, in that case, I’d say it’s more justifiable you’d just leave everything running on an emulation Vs a more fixed architecture.

It's make sense. May be DCO can do that. But not only analog. I just checked the manual. Some hybrids, like both Peak and Summit, seem to have a free-running OSC

Are you joking ?

A DCO, is just a digital controlled analog oscillator. Why they should do this, to save CPU Power? Very unlikely.

Peak and Summit have digital (FPGA) software oscillators.

I really don't know how they managed to do it. This thing blows me away.

It dosen't matter. Potentially possible. Nothing more.
Who care if it's digital. Hybrid can do.

To my ears. Xils-lab, Softube and Gforce sound more analog.
But Korg MP can do some crazy stuff.

I'm quite digging this, though it's far from perfect. Purchasing is a tough call.

It sounds great. I dig the filters, the VCA, the number of mod options, the voice controls, etc. I even think the number of good presets to duds is above average.

But there are definitely some issues here: the extremely limited MIDI Control is a big problem for me. The GUI is another problem area. I could live with it, but there's a LOT of room for improvement here with how they implemented the Edit panes and tabs. Do the OSC's need so much space dedicated to them? Does the keyboard view add so much value that it warrants hiding other elements of the GUI when combined with all that OSC screen real-estate? I don't know, it's just very awkward to use.

But I love the Korg is doing stuff like this even if I don't think the execution is perfect. Compare this to Roland's sofsynth offerings for example. Korg is doing cool stuff.

Agreed. The sound is great and the features are great. There are currently enough bugs and minor jank that it gives me pause about buying it right away, because I would hesitate before inserting it into projects, knowing there are tradeoffs to using it in its current state.

I guess that's not unexpected for a new release. I know they will continue to fix and improve stuff. But wavestate native still today has a similar problem as multi/poly native with editing knobs in the plugin GUI causing CPU "spikes" (probably thread locks?) I still use it despite that, but... hmm.

The other thing I really miss is MPE. Man, MPE is great for bending individual notes in a chord or doing micro-tuning to adjust the intonation of chords :(

But I don't want to end on a negative tone. This thing really sounds amazing, I like the layering, and it has some really cool modulation and sequencing features.

I was playing around with it again for a bit, and noticed that sometimes I would hear unexpected clicking right at note-ons. It's only obvious with certain combinations of settings. But it looks like something is going wrong because I see, well, this, when I've clearly set the attack to be longer, and I'm only playing a sine wave. This is playing one note at a time and waiting a moment between each note, to make sure it's not voice stealing going wrong or something.

It's quite noticeable in a few preset patches, like 'Air Drops'. Try loading that preset and playing up and down a scale.

If I turn up the "Delay" knob on the amp envelope by even a tiny bit, the click goes away. Hmm. Intended? Not intended?

edit: I'm pretty sure this is a bug. The delay shouldn't affect the attack transient like that, I think, and these attack clicks sound digital and unintended. If this was an intended artifact, I don't think the Delay knob would be getting rid of it.

edit 2 from the future: it was indeed a bug, and it has been fixed in multi/poly native 1.0.4!

is it me or is this plugin completely broken in ableton 12 with a push 3 connected. changing a preset takes literally 1 minute as it goes through every single parameter. I can see it in my push as its going through settings and changing them. wtf?!

After enough time (I think!), I reached to a general overall conclusion.
The analog section is wonderful. Can’t say it’s an emulation of Mono/Poly but sync and x-mod make this synth very aggressive and scream quite easily!
On the other side, I didn’t like the wavetable and wave shaping engines. Let’s say I have better sounding alternatives.
So, I’m still on the fence! I might buy it next 50% discount. The NZ dollar is really weak now, so that makes things really expensive :(
I don’t have major issues. One crush with S1. Works fine with Ableton. Very good cpu usage when using one layer and analog engine only (This is what I Will be using anyway). I didn’t tried on Mac though.
Using: Cubase Pro 15, Reason 13, Tascam US-4x4HR, MODX6, DM12D, LaunchKey 49, Yamaha guitar(Pacifica 612v) and bass (BB234) and some virtual instruments and synths.

Did You try the standalone ?
It ork fine on Reaper, Bitwig, Cubase

Does this happen with any envelope curve?
