United Heavy ADpak is a drum kit expansion (ADpak) for XLN Audio's Addictive Drums 2 aimed at the heavy end of the range. The territory is worth describing specifically, because heavy drum production is not simply "rock drums louder": the kick is heavily compressed and often sample-reinforced to hold a consistent attack at high tempo; the snare is tuned high and ringy or gated short depending on the era; the toms are tuned low with a strong fundamental for the big fills; and the cymbals are recorded to sit above a dense guitar wall rather than to blend — the recordings have to be made with that density in mind, since a kit recorded for a sparse arrangement can disappear under distorted guitars. Its place in the range is documented by the format's rules: ADpaks include complete drum kits and tons of production-ready presets, against MIDIpaks supplying beats and grooves and Kitpiece Paks adding individual snares, kicks, toms, and percussion. Because every ADpak loads into the shared Addictive Drums 2 engine, the design premise applies: build your ultimate custom kit by freely combining kit pieces from your Addictive Drums collection, or pick a starting point from hundreds of mix-ready presets for any style and adjust to taste — so a heavy kit's shells can be combined with another ADpak's cymbals, which is the reason a niche kit is worth buying on top of a broad one. ADpaks are commonly priced $69 to $89, with the Addictive Drums 2 Custom Collection letting a buyer choose 3 ADpaks, 3 MIDIpaks, and 3 Kitpiece Paks, and with the Addictive Drums 2 range and its MIDIpaks and Kitpiece Paks being documented as expanding your sonic palette with individual snares, kick drums, toms, and percussion, carefully chosen to complement your kits.
