The original Akai APC40 is one of the rare breed of products in the computer music age to achieve iconic status. Launched in 2009, the APC40 (followed by its more compact sibling, the APC20) was, along with the Novation Launchpad, the first dedicated, plug-and-play Ableton Live controller to hit the mainstream market. Five years later, Akai are releasing a re-imagining of the original APC40, the Mk2. Will it be as widely adopted as its forebear? We spent some time with it to try to find out.
