In my opinion the MZ beats the 740 in several areas...... The sound quality
is unbelievable! It's hard to believe that those sounds are coming out of a Casio.
My suggestion to you is this. Go the Yamaha's site and print out the specs on the 740,
then go to www.mz2000.com This is a full interactive tour on this keyboard. It's got to
be one of the best demo sites I have ever seen. All the info on the casio is there including full
lists of sounds, styles ect. One big thing to keep in mind is that the 740 lacks a true sequencer... It
lacks most of the features needed like copy, paste, and many others... Also the sounds on the 740 are as is, meaning
that you are stuck with them and no room for editing. The Casio has a synth engine on it so you can edit the voices.
There are just so many good features on the MZ, Go check it out and make a comparison. A friend of mine did a side by side with
the two and said the MZ in his opinion was the better of the two. I value his opinions too because like me he has been playing for over
20 years and knows a great deal about synths...
