Since we put the exclusive demo of the V-Piano on line from NAMM where we were ushered into a private room to see the new keyboard, we've had several requests to post higher resolution audio files of the session. Thanks to the marvel of modern technology, we did record them to a separate stereo recorder and have indeed now posted them at 48kHz/16-bit for you.
Once again, thanks to John Maul for the great demo and Sean and Amanda from Roland for making this possible.
Here they are (taken from the stereo output of the soundsource):
