drummachine - 1st programmable rhythm machine!
transistors made it possible ;)

you need a special controller to program it (some tried to built their own programmer). the WS1 or the WS-1 Memory Write Switch (both rare).
34 preset patterns an 30 free ones.. but well, I have never seen one of those prog switches.. but quite some cr78's..

the CR68 is the same,but not programmable!
the predecessor CR8000 is a non programmable unit. also nice old analogue sounds in here!

the little (extra) WS1 programmer (rare) ..
