The best controller we’ve ever used, the APC40 is a dedicated device for controlling Ableton Live. You can launch clips, control levels, tweak panning and send amounts, manipulate plug-ins and lots more. The backlit buttons and LED-encrusted knobs make it a doddle to keep informed about what you’re actually doing, and the whole thing is so damned intuitive that the inclusion of a manual is really just a formality. Astounding!
