swamiji,
Don't let the tweeking of converted styles on the MZ put you off..... It's that way with any board that converts styles from other makers. Regardless you'll most likely have to tweek them just a bit to get them to sound the way you want. The conversion is just a base for getting the style onto your board. If you use a Technics style you have to remember that the style was composed for the technics keyboard, which used that boards effects and so forth. So it will sound a little different converted on another board. Being able to convert them is nice because you can adjust the style to your liking as well. Tweeking the style isn't hard and doesn't take much work. A little more reverb here, maybe up the volumer there... It's really simple. I think the PSR-740 is a good board, but if you want a good sequencer, the MZ wins hands down.. More user space for styles, and extensive song editing as well.. Also the MZ has a synth engine, and you can really get in there and twist the sounds up....
