Hi,
Thanks very nuch for the information. I have visited the sites you have recommended and also Simon William site http://www.svpworld.com/tools.htm. I have downloaded the mp3 files from the two keyboards, with sounds, styles and I have heard them through the same sound card in the P.C.
Indeed the MZ2000 has much more features and it's more atractive. But, it seems that the quality voices imitation is a little better in the PSR740. Am I wrong in this conclusion?
Thanks,
Carlos Rodrigues
