Böhm 12/24 synthesizer expander demo 

All sounds from the Böhm.
The Böhm 12/24 is a fully programmable synthesizer from Germany.
It contains 4 Yamaha FM-chips. It was aimed at the market of organplayers and it is capable of some decent organsounds but it can do much more than that. It has a memory of 400 sounds, midi in out and thru and a pair of stereo-outputs.
The synth was delivered as a DIY kit, all parts were delivered but you had to essemble it yourself. It was also delivered under the name of Orla.
Böhm als made some very nice drumcomputers.
