Oh my! I forgot to mention one more very important point

4) All keyboards, regardless of being low, mid or high end, should have line outs.

Phones out delivers poor quality when recording. That's the reason I dont share my songs with SZ users.

5) the same applies to midi ports.

I am not a die-hard Yamaha fan. I heard some recordings of the previous Casio models and I admitted the WK3700 sounded better than my present keyboard. If only the new casios had 64 poly I would switch brands immediately.
