01Overview

FM Lab is a synthesizer from Steinberg built around classic eight-operator FM synthesis. Steinberg positions it as a modern take on the FM sound that shaped popular music in the early 1980s, with an interface meant to make FM design more approachable. Alongside the FM engine, it adds VA synthesis for a second layer of sound design. Producers working with FM-style basses, bells, keys and evolving textures will find it a focused option for building sounds from the ground up.

03In depth

FM synthesis and VA layers

FM Lab uses eight operators, the building blocks of frequency modulation, and combines them with additional VA synthesis. This pairing lets you shape the harmonic character of FM tones and then blend in subtractive-style elements for added body.

Steinberg describes the algorithm designer as intuitive, so you can route operators into different configurations and audition the results quickly. An algorithm finder is included to help you locate useful starting points.

For shaping movement over time, the plugin offers multistage envelopes that you can draw freehand, giving precise control over how a sound changes from attack to release.

Patch compatibility with DX7 and TX81Z

FM Lab includes FM-X and DX7 emulation and can import DX7 and TX81Z SYX files. This makes it practical for producers who want to bring existing classic FM patches into a modern workflow and adjust them with the plugin's envelope and algorithm tools.

The SYX import is a useful path for reusing sounds from older hardware libraries, while the drawable envelopes let you refine the results beyond their original settings.
