Standalone Audio has released Standalone, a lightweight AU and AUv3 plugin host for Mac designed specifically for guitarists and bassists who want to run amp sim and effects plugins without opening a DAW.
Standalone is built around the guitar practice and recording workflow. It hosts AU and AUv3 plugins with low CPU overhead, and includes a built-in recorder, looper, Practice Mode with real-time time-stretching (for slowing down tracks without changing pitch), a Scores and Charts viewer for keeping tabs and charts alongside your plugins, chromatic tuner, metronome, and global keyboard shortcuts for hands-free control.
Standalone is available now for $14.99 at getstandalone.com
