Thank you for this.

I've never had a Poly800 so I can't comment on how close this gets, however I have heard and loved a lot of old skool Detroit techno and this synth has the exact same feel and sound to it.

Excellent - oh and also thanks for the version that works on older macs lol my studio cheese grater loves it .

I think this sounds too good to be a close emulation of a Poly800, which never sounded good at all. The problem with it is that they have slavishly copied the original's UI and it really doesn't work here. You can't see the value of anything until you hover your cursor over it and there is simply not enough contrast between the background and the markings to comfortably read any of the parameters. Overall, the GUI is way too large, too, even at it's minimum scaling.

Overall it's an interesting exercise in showing why slavish emulations of old hardware is a bad idea. Some of FBM's other synths are absolute crackers, like Mono/Fury, but this one is way wide of the mark, I'm afraid. Some years ago Synapse made another Poly800 clone and I think they did a better job than FBM have done here. If you can find a copy of that for sale somewhere, it's a better bet, I reckon.


- Sounds nice enough, better than I remember a Poly800 ever sounding.

- Can't argue with the price.


- GUI too big at minimum size.

- Slavish copying of original UI hampers usability.

- FBM have much better synths than this one.

Sounds close enough to the hardware to me.

It might not a be a 1:1, but the spirit is there.

Overall, I get poly-800 vibes playing this.

Comes with an awesome little set of patches.

This thing generally excels at evolving pad sounds, cute keys and sound.


It's limited, but that's why you want to use it.

A good clone of a niche cheapo synth from the past.

Thanks fullbucket.

4 stars for even creating this beast. The most hated/ignored synth on the planet. It sound way better than I remember, but it lacks the constant noise, distortion and whining...no just kidding. Great work.

5 stars if you add a way to import real poly800 patches.

I'm so happy I've got such faithful emulation of this great little synth. It has its unique character! What a pleasure to shift back in time...

I'm getting crashes in Tracktion Waveform 11 when opening the GUI.

Is it working i a different host? Maybe the latest LICE-based version (see my website) works on your machine?

Cheers, Björn.

LICE is nice. Works great, THANKS.

Sorry I missed the very clear suggestion to try this version if the other didn't work.

No problem! Glad it works! :-).

Super excited to try this ad I owned an original. Reaper crashes every time I try and load the VST sadly (Win 7 P).

Did the LICE version that Full Bucket pointed out not work for you in Reaper? It works for me in Reaper 6.11.

Until now all Full Bucket Music plugins have worked extremely efficiently and flawlessly. I'm using linux and the reaper DAW through WiNE. Fury800 is the first VST that doesn't work - the GPU accelerated version at all and LICE does not display the interface elements correctly (and VST window size too). When I saw that this plugin appeared on KVR with the option of changing the size, I was extremely happy. Meanwhile, it is the first VST that is not suitable for use in my environment. Nevertheless, thank you for the whole set of great vst's. The above only informs that something has changed in GUI development, which stopped the possibility of using this plugin in my OS.. I suspect that every new plugin will also have the same problem. All the best.
