“You are bidding on Wersi DX400 Beta from the mid 80’s which is faulty.
I purchased this keyboard many years ago from the original owner from new. This is a unique piece of kit and although made in the mid 80’s it has a very analogue 70’s sound. In particular the string patches.
This machine was fully working until moving it from downstairs to my son’s bedroom. It now plays notes at varying pitches, not the correct notes. This may be a dry joint or a card loose inside. I have not even taken it apart to look as we want the space in his bedroom.
I have some documentation for it which will be included in the sale. It also has a MIDI interface, and from what I have found on the internet you have to use a combination of the ‘W’ ‘E’ ‘R’ ‘S’ ‘I’ buttons to enable it.” Click here to visit listing on eBay
