Description
FB-02 by Full Bucket Music is a software instrument that recreates the sound generation section of Yamaha's 1986 FB-01 FM module. It focuses on compact four-operator Yamaha FM rather than modern wavetable-style sound design, so the tone leans into glassy keys, metallic bells, sharp basses, digital brass, and bright 1980s module character.
The instrument includes the original factory ROM sounds, additional patch collections, and a program browser for moving through seven banks of 48 patches. Unlike the hardware, the plugin lets you edit everything directly from a resizable interface, including sounds that were fixed ROM presets on the original unit.
FB-02 is also useful as a modern editor for the physical FB-01. SysEx import and export, direct patch sending, and full MIDI Learn make it practical for hardware owners who want a DAW-based librarian and editor instead of relying on vintage utility software.
For sound design, the draw is the mix of classic FB-01 algorithms, four matched operators, TX81Z waveforms, MTS-ESP microtuning support, and low native-C++ CPU use. It is still Yamaha FM, so it can get bright and unruly, but the single-window workflow makes those tones easier to shape than many deeper FM synths.

Frequently Asked Questions
What hardware does FB-02 emulate?
FB-02 simulates the sound generation section of the Yamaha FB-01 module from 1986. It is centered on four-operator Yamaha FM synthesis rather than the six-operator DX7 architecture.
Can FB-02 edit a real Yamaha FB-01?
Yes. Full Bucket Music states that the user interface can be used to edit the sound of the original FB-01, and the plugin supports SysEx import and export for patch transfer.
What changed in version 1.1.1?
The 1.1.1 release notes list a SysEx import fix. Version 1.1.0, released the same day, added the TX81Z waveforms and fixed MIDI CC learning and VST3 parameter reporting.
Which download builds are hosted here?
The hosted Windows download is the standard VST2/VST3 ZIP, and the hosted macOS download is the standard VST2/VST3/AU PKG. Full Bucket also provides separate CLAP, AAX, and legacy N builds on the official page for users who need those formats.
