Below are 3 vinyl recordings from 1987/8 that feature various Wersi instruments which I thought you may like to listen to, (Not the usual Euro sound) along with the LP covers.
The 1st is called Uberduck by Uli & Mike; they use the Wersi MK1 SIII Synth, CX 5 Drum Machine and Multi-Track 16 Midi Sequencer which were released around 1985/6.
Uberduck The 2nd is called Digital Sound Sensation 2 by Curt Prina, and features the Wersi Spectra Organ. (Part of the CD line launched in 1987)
Digital Sound Sensation 2 The 3rd is called Wersi Special Sounds by Dirk Schmalenbach, and features all instruments in the previous recordings + the EX10/20 Midi Expanders.
Wersi Special Sounds Enjoy
