It's a great effort and really generous of Fullbucket to put this out there for free (or donation)

As far as nailing the 800, this is the best VST yet, unfortunately one of the things I was saying to Zerocrossing is that the paraphonic nature of this particular filter is iMO what makes emulating the 800 almost impossible, and this is no exception, it's way off, the filter does not act like a Poly 800's filter at all !

Sorry to be negative as I think Fullbucket is a great designer, I love his Trident

I love that, the opening patch just reminds me of my Korg Poly61 and why I love it- it's that wonky Korg sound ... I've only heard it from their synths, I love it

Unfortunately, no, he didn't come close to the OG. Just try the patch I've shared above [1] on the Fury-800 and compare with my recording of hte Poly-800. No similarities at all.

[1] Korg Poly800??

D'loaded both, I'll check for fun later - it has a nice VST UI though!

Nice for free and like the interface, it has some useable sounds in there and some of the patches are reminiscent of the Poly800 but overall missing the quality of the original by quite a bit.

Patches 17, 23 and 58 are probably the most convincing patches.

so you quite like it then.

Just noticed that myself

OK, I played a bit more with the Fury-800. Envelopes are very much off. The time scales are very different. The same holds for the filter. I'm not sure if it sound anything like the Poly-800 since I can't get it to sweep correctly: The filter doesn't really open up with CUTOFF 0 and EG INT 15. Moreover, the filter (or the filter envelope?) does not reproduce the OG's stepping ;-)

I have come closer to emulating my patch above, though, by tweaking the EG parameters.

Overall, I think, that the Fury-800 actually can be "fixed" to get closer to the Poly-800. I'll send him a note to offer some help if it's wanted.

I've e-mailed him too, and I'll be sending him some examples of how things "should" sound, based upon how the parameters are set in the plug-in and the real thing. Fortunately, he's receptive to this kind of help, and is willing to try to improve the envelopes, filter, and other things.

For anyone still interested in trying out a VST version of the Poly-800, Björn has made several changes to the filter, envelopes and other aspects of his "simulation". I worked with him quite a bit on some aspects, and I know a few others did, too. Overall, I think he's a lot closer to getting the sound of the Poly.

It won't be perfect of course because 1) that was never his intention with any of his simulations; 2) some things done in hardware can't easily be simulated in software; and 3) Björn doesn't have a Poly-800, and was relying upon a few of us to provide samples of different things.

With some of my own patches, this new version is almost indistinguishable. With patches based upon the Poly's "sawtooth" waves, the results aren't quite as close -- but they're still good. (Of course, this is due to the way the Poly creates the "sawtooth" wave, and the way it interacts wit the filter.) When you add in the fact that the envelopes for the oscillators aren't the same as the non-linear (and seemingly erratic) envelope for the filter -- and that no two original Mk I Poly-800s sound the same anyway -- you begin to see how large an undertaking it would be to emulate this synth. And that doesn't even address the Mk II version of the Poly, which had snappier filters and different effects which altered the sound quite a bit.

Also new in this version of Fury-800 is the "Fury-800" mode, which makes the synth more what Björn wanted it to be; the Poly-800 mode is what Poly-800 users will probably want to try out first. Both modes offer some cool sounds.

Due to the holidays I decided to rediscover this synth and did some programming. I actually never programmed it before. In a creative spark, I made about 10 own patches, and this synth now looks more powerful to me.
This ambient theme came to my mind and I just finished it yesterday. I think Poly 800 is not that bad All sounds here are from Poly 800. And actually very little effects.

Fury800 now at v2.2 as of 11th November 2020.

Pretty cool! That sounds like about three tracks of the Poly, is that right? You have some nice textures there.

Steve

Just hear how this thing can sound with the filter mods




Really scratching my head how anyone can not like this synth

Thank you! Technically, all four tracks but I could easily fit them into three.

It sounds better than the earlier version and captures the essence of the sound of the OG, not quite a replacement yet as there is some extra magic going on in the hardware but its impressive, certainly useful in a mix. I personally rate the 800 quite highly, its still one of my favourite synths and a lo-fi alternative to a Juno.

I've owned a Poly 800 II since they were current, it's a slightly different beast with a delay instead of a chorus, that can be used for Chorus, Flanging, or Delay, but this really seems to capture the Poly 800 vibe in a plug good now.
