abacus,

This is similar to what we're doing - hence not all chords need to be sampled ... just the strategic few! Ofcourse when you look at Audio drums, Audio Bass, Audio chord parts, a lot of processing is required for real-time (unlike say the example shown here which is close anyway) -

... which is why the Intel P3 becomes useful to upgrade to. Audya also has the AI to react in real time/live to the chord changes either via Arranger chord input, or Midifiles or both. So even a Midifile (the way you see and hear it now) will be perfected with Audya! Notice the difference in the fluence of chord changes from the Prototypes we have now versus those shown at the Namm 2008 or Frankfurt 2007 shows!! A P4 might eventually be used, but not yet confirmed.

Thanks,

AJ
