Yep, despite differences in reverb, the Tyros4 sounds mellower. I took in a lot of my styles, and the OTS would bring up the same voices and effects on the Tyros5, as well as the same parts (and their settings and effects) in the styles.

Now, if I was going the other way, the Tyros4 may not "see" the same instruments and settings due to T5's new voices, so probaly harder to make the comparison that way. I will try it, if I get the chance.

The difference may not jump out at a person who doesn't play Yamaha instruments a lot, but, I do, and there is a distinct enough difference to my ears to be able to say the Tyros4 is mellower, or warmer.

The T4 still has all the detail I like so much, and the Tyros5 is far from being harsh or hard.

Let's put it this way...if I had to get a Tyros5 for some logical reason...say Fran borrowed my Tyros4 and loved it so much he wouldn't give it back...I know I'd be very content with the Tyros5, and I'm sure I could get it sounding mellower, much like the Tyros4.

Conversely, there is a HUGE amount of tweaking available in the Tyros4, with the Filter, Master EQ, extensive Compressor settings, Main Voice, and Style Voice Filters and EQ's, and I might be able to get it sounding a bit more like the Tyros5.

But, I do believe their overall basic sound is definitely different, especially out of the box.

One thing for sure...my buddy sure loves the Tyros5-76...he says it's the "Lexus of arrangers".

I have to agree with him...it is pretty posh. If you want a great sounding, deluxe feeling semi-weighted 76'er, it's a great choice.

PS...I also found the PSR-S910 mellower than the S950 (and almost identical to the S750), when played through the same system. It may be different D/A converters, and maybe that's the reason for the above variations as well.
