Full Bucket Music have released a software emulation of the 1977 Korg PS-330 polyphonic synthesizer. The FB-3300 will run as a VST instrument on Windows or VST/AU on MacOS and is completely free. That’s nuts, so if you like these sounds why not throw them a donation.
The original Korg was a huge two-piece machine with a Moog style, wooden enclosed synthesizer panel with a separate keyboard. They were plugged together with what can only be described as the ugliest cable known to synthesis. But it was one of the first polyphonic synthesizers. It quite literally stacks together 3 PS-3100 synthesizers to produce 48 voices and 48 VCOs, VCFs, and VCAs. And it’s another one of those synths that can lay claim to aspects of Vangelis’ original Blade Runner score.
The FB-3300 virtual instrument claims to emulate the behaviour and controls of the original synth. The GUI follows the hardware with the three individual polyphonic synthesizer sections or “Blocks” which are then combined in a mixer block. The oscillators are band-limited and the filters are classic two-pole lowpass. There’s a resonator section and two modulation generators per bank. It even has the microtonal functionality of the original. And all the parameters can be MIDI controlled.
It’s been coded using native C++ and so should run very efficiently. It’s free so there’s no reason why you shouldn’t go and try it out right now.
