GEM was an italian keyboard company that is now out of business. The Gem Genesis is a number a years old now, 6-9 years, not to sure on the exact year. It was a good keyboard in its day, very state of the art, with cd rom and a lot of extras, the styles and sounds were good, somewhat like ketron's but not ketrons. I would not purchase GEM since if you were to have any problems, I not sure if parts are available or customer support does not exist.
