I had the Technics EX-10 Organ since 1998. It was given to me by a piano tuner, he gave me a Yamaha FM Sound Generater FB01 that came with it as he gave me the organ. I still have it, it`s on top of my Technics PR-305 Digital Piano. The Technics EX-10 served me really well, It didn`t have much polyphony to play with both hands on one manual, but for playing one hand on one manual, while playing with one hand on another manual. The Technics EX-10 doesn`t have a disk drive, so you had to put one in. the sound wasn`t very good unless you hooked up something like a Behringer K3000FX Amp to it, or hear it through the head phones, and quite portable. You can look up www.manualslib.com/ on how to operate it.
