I bought the Prime 4 and its an excellent controller. It eliminates the laptop usage. My only 1 gripe is not having a sampler function to drop my jingles, could you guys do a firmware update for on screen sampler? it would make this a perfect fit for mobile and radio use. This is all that is missing from this controller. PLEASE INCLUDE A SAMPLER FEATURE FROM THE SD CARD SLOT.
Like the below thread in the feature request section, the more likes then the higher chance it has of bring implemented.
