Full Bucket Music Fury-800 v2.5: free Korg Poly-800 Synthesizer emulation gets an update - November 6, 2025

Full Bucket Fury-800 v2.5 is out now: new major update refines the free Korg Poly-800 Synthesizer (1983) emulation for macOS and Windows.

Good news for Full Bucket Music plugin fans. Björn, the developer, has just released Fury-800 v.2.5.0, an update for its Korg Poly-800 emulation. Following a significant update in 2020, the free plugin is now getting another boost.

The new update 2.5.0 introduces a reworked Poly-800 mode, which more closely matches the original hardware characteristics. According to FBM, they refined the filter behaviour with updated resonance, envelope intensity, and trigger mode.



They also modified the modulation generator to match the Poly-800’s original characteristics. This includes:

• waveform: it now produces a triangle wave (only in POLY-800 MODE)
• oscillator: values of parameter 81 (frequency) and parameter 82 (delay) are matched to those of the original hardware
• The “slope” of the delayed modulation contour was adjusted, too.
• adjusted mod range (about two notes)

Alongside this, Full Bucket Music added a new MIDI CC2 (breath controller) parameter to the Fury-800. It’s now possible to select whether the VCF modulation is controlled by MIDI CC 1 (mod wheel) or CC 2 (breath controller.

Additionally, the BRIGHT function has been recalibrated to match the Poly/EX-800 characteristics.

Thanks a lot, Björn, for this second major update for Fury-800.

Full Bucket Music Fury-800 is a free download and runs as a VST, VST3, AU, AAX, and CLAP plugin on macOS (native Apple Silicon + Intel) and Windows.

Korg Poly 800. My first real synthesizer in my first band. Keyboard had only 4 octaves and no sustain pedal. Can't believe that that is already more than 40 years ago and I am still just 28 years old......

 

Full Bucket has some great stuff at a very low cpu suction pressure.
