A manufacturer of Eurorack modular synthesis modules and equipment, based in Barcelona, Spain. The company has a line of modules focusing on West Coast methods of synthesis, with complex VCOs and control voltage processors; they also feature a MIDI/CV converter module which is equipped to receive MIDI over USB. Their feature product is the Shuttle, a skiff pre-configured with five specific modules.
Originally Endorphin modules had panels with a gold background, and featuring some rather whimsical graphics. However, they are transitioning to panels with a black background and generally fewer graphics elements. Of the modules which were originally issued with the gold panels, the ones still in production can now be had with either style. Newer designs come with the black panel only.
