Has anyone purchased the 170 new rhythm styles of the Americana series? I already have the Viking SD card that I purchased from Technote for $119.99.I was pleased with them. I'm curious if anyone has used the Americana series.Does the 30 banks of new performance pads work on my Kn2600? Also, do the 170 new styles have good presets? Are they really "new" styles? I'd like your input.
