The Future of MIDI Generation

W. A. Production and Liminal Sphere proudly unveil LOOP ENGINE 2, the trailblazing successor in their lineup of multi-voice loop tools, now even more potent with cutting-edge enhancements.

LOOP ENGINE 2 continues the evolution of MIDI generation, building upon the esteemed legacy of the CHORDS plugins while breaking new ground.

Progressions for any genre in no time

No matter your preferred genre, Loop Engine 2 will effortlessly generate note progressions based on chord shapes and rules that you select.  This plugin is your one-stop shop for assembling tonally and rhythmically engaging patterns - from simple to complex designs. 

Intricate loops across multiple tracks

Loop Engine 2 into your DAW project is now easier than ever. The eight voices of the plugin can be routed to any number of MIDI instruments, using our included Loop Engine Listener plugin. With these tools, you can create intricate loops that span across multiple tracks in your DAW, or use the presets as a starting point for crafting fantastic loops.

LOOP ENGINE 2 goes beyond the norm, enabling you to craft MIDI loops with unprecedented intuitive controls to sculpt the algorithms, ensuring a constant stream of inspiration and innovation for your tracks.
