Audio examples

Please note that this ReFill requires that you have the Propellerhead PX7 Rack Extension installed on your system.

The Yamaha DX7 is one of the most popular digital synthesizers ever made, known for its signature sound. Propellerhead Software made a faithful emulation of this FM synthesis legend, the PX7 Rack Extension. Programming its unforgivable FM operators was not an easy task, but we did it anyway to satisfy your needs. With precision and care for the sonic details, we made the most modern-sounding textures that this synth can do, mixing it with a bit of the retro vibe and feel.

Product details

The “Extension ReFill-PX7” contains a perfect combination of deep basses, metallic pads, crystal clear bells, smooth keys and special effects that are only feasible with this synth legend. Plus a generous collection of patches inspired by some of our favourite retro synths and a selection of percussion patches, making them as expressive as they can possibly be. We believe that this ReFill will inspire you, in recreating the memories of the past as well as in songs of the present and future.
