killer demo of the BK5 Fran...
Roland surly has such a rich quality sound as shown in so many of their products which makes them stand out. I gotta tell you these MOTL arrangers such as the BK5, Pa600, S950,etc, have raised the bar.....they are all very close in so many ways feature & sound wise,..Same thing goes for TOTL units also ....it's just the players choice which to buy learn, plays & enjoy. This silly mine is better then yours is getting a bit old...all these different demos prove it beyond a doubt.
At this rate it all comes down to the players abilities, experience, and creativity.....
just buy one and start enjoying music I say!
