Sounds a lot like the early Yellow Magic Orchestra records... They maybe used the Sigma!

Worked on Windows 7 SuperNano as well so far. Has a very low cpu usage. Definitely no cpu-hog. If you can't get it started in your host like savihost or Reaper, try opening the dll file with a hex-editor like HxD. Search the dll-file for the string "dll" and check if every mentioned dll-file is actually present in your C:WinowsSystem32 directory. If there should be a needed dll missing download it on a site like "dll-files.com". Worked for me a few times. Greets, Ersin.

The fact that there are like 19 separate Oscillators that can all be turned on or off in any combination means this synth is a lot more complex and trickier to use than it looks. Also the sounds aren't that nice IMO. CPU usage seemed pretty low to me.

This is the only Full Bucket plugin that has high CPU consumption for me. I can have multple instances of the others and something like Omnisphere, but even one instance of this in Reaper makes sessions crackle. Weird.

Hey... maybe I do anything wrong... I tried with VSTHost on Windows 10. And it does'nt work. Also FB3300 won't work. Any Idea?

They definitely work under VSTHost as this is one of my workhorse tools for debugging.

Some of my mac AUs do not work on the newly updated version of Logic Pro... So I am switching back to Ableton and will reinstall them there...

Quirky synth but sounds great.

Real fun to play and it sounds powerful. I guess, it sounds close to the original, which I never owned, but tested quite often that time (early 1980's). Easy going GUI, but with the hidden additional controls also perfect tweakable. Love it!

Ideal for retro-sounds, sounds and works very fine. A lot of fun to work with or combine with other synths; hardware & VST! Thx a lot

Some interesting old school sounds. Reminds me of Alan Parsons and Dr. Who. The old Dr. Who... I think I can use this!

I've been a FBM fan from the start....but Stigma is my current fav. Nice presets and easy to come up with your own sounds, especially if sound design is not your forte( like me ).Good job FBM and thanks.
