I saw the new T3 video too...styles are good, this we know all, but the sounds not impress me at all.
SA2 is what they shown in the video demos??
this is just one key midi controller that activare a different layer sounds and the sounds response different.

hey...with gigastudio and Linuxsampler editor: http://linuxsampler.org/screenshots/gigedit_0_0_3.png
we can make totally the same!
for each sound we can add a new layer and add a new midi CC controller, the result is the same like a SA2.

4 years OLD feature...

Soon we release also the 32 sliders and 32 keys ON/OFF programmable CC controller, mean 64 CC new controls = SA64??
