Shows they are listening. I have always thought that the clarinet was so bad it was unusable as a solo instrument and always used flute or oboe instead. Pretty cool. As previously stated. Won't know if the same can be reproduced in realtime but given the other voices in the T2 I would expect that it would. Don't expect a download to T2. One, it doesn't get you to buy a T3 (Yamaha's goal, of course) and two, even if you could load time of samples is way to slow on the T2 to be usable for any normal gigging musician (can you wait several minutes for keyboard to boot up and confirm all is well and ready to do?).
