So would you know about the MP3 recording on the T4?

If it's like the S910 it will playback mp3, but actually records in .wav.

Hello All You Yamaha Fans,

I listened to many of the Tyros 4 demo's this morning. Yamaha seems to put a lot of emphasis on the human voices.

I like the incorporation of the voices in several of the styles.

The overall sound engine to my ear, appears to be the same as the 3.

There is no doubt Yamaha builds an awesome arranger. In fact their entire line up of keyboards are really good.

From what I've listened to so far of the tyros 4, It may be difficult for me to justify the expense involved in upgrading from the 3.

I'll devote more time to listening to demo's as they become available and re-post a more detailed review.

So far, I really like what I hear.

Jim
