Obviously some of the posters here have not yet read my previous posts & reviews, (Understandable as they have been spread over a number of years) however it is only the T3 I have issues with (I haven’t heard the S910 so can’t comment) as the rest of the range is fine, because they have a nice CD quality sound (Not my cup of tea, as I prefer a more live sound) which is great, the T3 on the other hand really is a dog, as apart from the SA voices it just sounds so compressed.
I regularly go to live music venues, (One of the advantages of where I live) so know exactly what live instruments and players sound like, and I can give you a 110% absolute total guarantee that apart from the SA voices, T3 doesn’t even get onto the bottom rung of the ladder.
The closest hardware board to real sounds (Personally) I find to be the Korg/Ketron range (With or without DNC) as they really do sound more like a live band.
The above is why I never compare boards with boards. (I only compare boards with live sounds)
BTW If you are after Jazz & Big Band sounds, one of the best value ways is this http://www.garritan.com/products_jabb.html (They really do sound like real instruments, and at an amazing price)
