The Arturia AstroLab 37 is a compact, standalone stage keyboard that transforms Arturia’s acclaimed software instruments into a powerful, portable hardware instrument. Launched in late 2024 as a streamlined alternative to the 61- and 88-key versions, it delivers professional sound design capabilities in a lightweight 37-key format.
