I`m not sure how you could emulate an mpc PA with an apc 40.
It is a midi interface and contains no internal storage capability, it has to be used with a laptop or pc.
It works in a completely different way to the mpc.
You might be able to reprogram it all within Max for live to work like an mpc but I have no idea why anyone would do that.
Or I suppose you could set your clips to trigger once and set them up in a grid and do it that way but it wouldn`t replicate an mpc


A laptop is hardware. People seem to confuse this point, and I never understand why people make a difference.

The APC 40 is just a midi interface that happens to replicate the GUI and functionality of what is happening on your ableton screen. That the ableton GUI is already a revolution in live pa functionality is what makes the APC 40 so amazing.
