I saw the recent thread on the nanoseries and thought I'd ask which drum controller you think is a better buy - the padkontrol or the nanopad. I've had my eye on both but can't make up my mind. Obviously the price is an issue here. The only downside I found about the nanopad is the roll feature is more limited than it is on the padkontrol. Would that be a problem? I'm using steven slate drum software with pro tools, and i'd mainly be playing metal.
