Tapas, I've seen all of Roland's demos for the V-Piano online, and actually, the feature that stood out for me MORE than just about anything is the ability to retune, or detune any and all of the strings to whatever degree you want (or in what area of the keyboard you want, it doesn't have to be even). So, if what you heard was entirely perfectly in tune, lacking 'character', I just don't think that you got a chance to explore this part properly...

But thanks for the report. Glad you came here and shared. Can't wait to try the V-Piano board fro the RD soon. Will it work with a FantomG?
