The FB-3300 is a software instrument designed for both Microsoft Windows and Apple macOS platforms, offering support for multiple plugin formats including VST2, VST3, CLAP, AAX, and AU. It faithfully recreates the legendary KORG PS-3300 Polyphonic Synthesizer from 1977, capturing the authentic character and feel of the original hardware. Developed in native C++ for optimized performance, the FB-3300 ensures efficient CPU usage while delivering rich, classic analog sounds.

This synthesizer plugin features three independent polyphonic synthesizer blocks, each equipped with band-limited oscillators and classic two-pole lowpass filters, enabling lush and dynamic sound textures. The resonator section and dual Modulation Generators per bank provide extensive sound shaping possibilities, complemented by additional elements such as Sample & Hold and a paraphonic Envelope Generator. Its semi-modular design allows for creative patching and sound customization, while a micro-tuning option offers precise control over pitch variations.

All parameters of the FB-3300 can be effortlessly controlled via MIDI Learn, allowing seamless integration into any MIDI setup for expressive performance and automation. The plugin supports both 32-bit and 64-bit environments across Windows and macOS, making it accessible to a wide range of producers and musicians. Whether used in studio production or live performance, the FB-3300 delivers a vintage analog synth experience with modern reliability and flexibility.
