The Mercury-4 is a said to be a (mostly) faithful recreation of Roland's iconic Jupiter-4, which improves upon the design of the original by adding 16-voice polyphony, infinite patch storage, velocity sensitivity, and MPE support. Roland's Jupiter-4, first manufactured in 1978, offered limited patch storage and only four voices of polyphony.
To accurately replicate the sound of the Jupiter-4, Cherry Audio have modelled the plugin on a vintage copy of the synth owned by Greg Hawkes of '80s new wave legends The Cars, that can be heard on their double-platinum 1981 release Shake It Up. The Mercury-4 also comes with an integrated emulation of Roland's famed tape delay, the Space Echo.
