Hi...

I had few OB8 keyboards in my studio...(One is stil here)

I notice that not all OB8 have same keyboard.....
in some OB8 are keyboards and keys same as : POLYSIX, Memorymoog,
Prophet 600, Poly61........

in other OB8s there are not just plastic keys..that keys are very look
like this from Polysix but have metal part under key..sticked with glue
and some little diference in design...(I found same keys only on
Emulator II)

bouth are from same manufacturer....

send me a picture (of a key ..from bouth sides)...maybe I can help...If
its Polysix keyboard I have complet one working for
sale!!!!!!!!!!!!!!!!!!!!

Hope this helps...
