Quasimidi Musikelektronik GmbH was a German synthesizer manufacturer from Hesse. It was founded in 1987 by Friedhelm Haar and Jörg Reichstein. It was originally based in Kirchhain, but moved to Rauschenberg in 1998. The company folded in 2000.

A groovebox is a self-contained electronic or digital musical instrument for the production of live, loop-based electronic music with a high degree of user control facilitating improvisation. The term "Groovebox" was originally used by Roland Corporation to refer to its MC-303, released in 1996. The term has since entered general use, and the concept dates back to the Movement Computer Systems Drum Computer in 1981 and Fairlight CMI Page R in 1982.
