I am considering buying a used digital keyboard sampler. I did have an Ensoniq Mirage DSK, but I did not like the split keyboard, and the fact that you could not load in new sounds while playing ones already in. Plus I did not think it a practicle instrument. I read in Keybaord Magazine a while back that a good keyboard sampler to buy would be the Ensoniq EPS-16+. A dealer even told me I should consider and EMAX sampler. Also what about the Roland S-50 I have heard good and bad about this instrument. Or the W-30, or Casio's FZ-10. Any help would be greatly appericated.
