I can hear a breath sound on saxophones & a hand tapping on a guitar body but that's all so far.
A bit disappointing though.
Hi Bob --
I enjoy the Super Articulation saxophones and guitars the best. They seem to enhance whatever gestures I play.
That said, Yamaha have kind of stretched the application of "Super Articulation" into marketing territory. For piano, it might be a key-off sound -- not so audible in a mix.
Regular Super Articulation is an out-growth of MegaVoice. Inside the Yamaha software, SArt is kind of a script that plays an appropriate sample in response to a playing gesture. To get an idea of what's available, check out the MegaVoice which is most similar to its SArt voice, e.g., 50sVintageSolo (SArt) and 50sVintageFinger (MegaVoice). Pages 21 to 25 in the Data List PDF map out each of the MegaVoices. You can see the "ingredients" that go into each MegaVoice and, probably, the equivalent SArt voice. That exploration might give you an idea of what to expect from particular SArt voices.
Hope this info helps and isn't TMI -- pj
