Awsome little Ableton Live tool.
This guy is great. The APC 40 is geared more toward the live club user, However, the APC is geared more towards the home studio. The APC still offers a hands free experience like the APC40. You can control Live sessions view with just this device. Pair this up with push for the ultimate hands free operation. You can also make beats with the buttons. But they're not volcity sensitive. Great little device if you're sick of the mouse.
