RAX turns your Mac into a virtual rig for live performance, slaving instruments and effects from another app or offloading DSP to a second computer. With its streamlined UI, this is an easy way to play AudioUnit instruments and process live audio through your AudioUnit effects. One-touch record lets you capture a great riff without delay.

Rax comes with many features such as multiple synths per rack, flexible effect routing including insert, send and master effects, a 16 channel mixer, and support for live audio inputs.

MIDI features include layering, keyboard and velocity splits, multiple inputs, host based MIDI learn for AudioUnit controls and external MIDI clock sync.
