What Synth Is This ?

Any one can tell what Keyboard or Sound Module is this? sound like Roland...
I really like these Choirs, Strings, Acoustic Guitar, Pan Flute, Mandolin Tremolo, Piano, Electric Rock Rhythm Guitar, and some drums...
I dubbed this from old tape to CD... The links contains intros from some songs from this tape...

It sounds familiar, is either a Wersi Organ or a Dr Bohm/ or now called Bohm Electronics, both have a German origen. I recall having a recording on one of the organs mentioned, very much like what you sampled, that was several years ago (late 80's to late 90's).
