Stein Strings

String machine with an FM layer

Strings with a soul and a second voice. Layer A is a lush ensemble string machine; layer B brings 124 FM sounds to put under it. Together they sound like nothing else in your plugin folder.

What it does

Ensemble strings

Register (8′, 4′ and both), bow, glass, tone, ensemble and motion: the thick, moving string sound that filled a thousand records.

FM layer B

124 FM sounds — pads, choirs, organs, bells, brass and more — under the strings, with its own pitch, envelope and mix.

Mutate on five axes

Bright or dark, short or long, moving or static, soft or aggressive, dirty or clean: push layer B in the direction you want, then undo or reset.

Four starting points

Strings, Pad, Glass and Cello: one click to a playable sound, then shape it by ear.

Room

A space that sits the strings in the mix, from close to wide and deep.

Mono, Uni, Poly

Full chords, a single line or a stacked unison lead.
