viocaia,

I know that there are not so manny people using SD-1+ but those that use it tell only good words about it (although they might be subjective, most of them had or still have other keyboards, so I guess they can be trusted), and I know some recording studios use Ketron keyboards as well.

I want to buy the keyboard for home use, and would like to play mostly rock (old rock from '60. and '70. but also instrumentals (J. M. Jarre, Vangelis, etc.). From what I see, SD-1+ has sequencer and I can put any sound I want, but it's much easier when I already have it (although on S-900 there is no possibility of extending the keayboards with new sounds). For electronic music (synth and pads) Roland E series also look quite good (about 1000 sounds without GM), but Yammie is kind a easy to learn.

But back to the theme of the topic, I hope someone will try this IDE to CF adaptor, and I hope it will work, cause this way it would be much easier to use the keyboard with PC, adding new songs, setups, and everything.
