Deanne,
yes the buttons are still rubber but the main white ones are shaped differently. Instead of being square they are shaped with a down angle making them feel much better.
Shim, I know how to make a video but don't know how to upload here. I've never done it before.
Also Shim, you asked about using superarticulated sounds when recording from scratch and after we got off the phone I took a look at the PSRS910 and can see that you don't even have the choice to select a superarticulated sound there but on the PSRS950 all the superarticulation sounds are available and they do work.
As for using the audio drum tracks when going into the style creator and assembling different sounds on the 8 style tracks I can see you cannot do this. If you select an audio styles drum track you just get a metronome sound instead of the newly choosen style track.
