Dynacord ADD-one Drum Synthesiser
via this auction
"This is a very rare Dynacord ADD-one vintage drum synthesiser.
It is working, although the factory programs were lost when the battery was replaced (yes, they should have been backed up first).
The ROM samples were obviously not affected but the synth parameters/programs were lost. You can of course program your own sounds but there were some very nice patches in the original set so it might be worthwhile trying to find a copy."
