Well for starters I'm not an Audya owner, but I own a ketron. I heard all 50 demos and its a nice board, great sounds but I would get very bored with it just like the other yamaha I owned. The right hand sounds are great but the styles are still to cd like, not like the live band sound that the ketrons have. I'm sure anything that is on the T4 could have might as well been on the T3, so why spend $3500-$4000 all over again. Yamaha makes great boards but not for me and the style of music I play. There great for american ballads, club/dance etc. but Latin is a no-go. I hope their latin section is better, but knowing them they just re-packaged it again.

Well I'll pass on this one, good luck to those who buy one.
