AKAI Professional APC 40 Mk2

I've bought it 4 years ago.

Pros:
It is very steady, very easy to use with ableton live, superb if you use it for triggering clips, mixer and fx processing.A very good daw controller.
Good for live shows and studio. Very nice light buttons colored function. It helps you understand without looking on the screen which clip is playing and what you can choose next. It is a plastic but solid enough hardware.

Limitations/Cons:
Fx knobs: The fx functions are following a random appearing order on the dock, depending on the specific effect you want to manipulate. So you have to customize sometimes.
Not easy to use the volume faders, if you want control more than 8 channels.
The volume faders are not reacting according to the values / (fader position in the software) of the new channels.
If you move them a bit the track volume can change rapidly in to an extreme high or low position.

Problem:
Until few months ago it worked perfectly well.Then a problem with solo buttons occurred. The buttons suddenly stopped working - also no lights on -. AKAI told me there was maybe a problem with the usb connection/power system.
Thanks to thomann warranty and the great work of thomann service team it now works as new.

I recommend it even though the cons and the solo buttons problem.

Setup was such a breeze that it was almost counter-intuitive. I?m so used to having to download remote scripts for Ableton, that I spent ten minutes trying to figure out where to download one, before I read the manual and found out it was already installed. Go figure... Once I?d chosen the APC40 MK II from the list of hardware, I was up and running. And, I have to say I was impressed from the start.

Construction-wise, and like all of the current Akai controllers I?ve seen come around in the last few years, the APC40 MKII is nicely put together. The pad/buttons feel and look really nice. There is also high level of LED goodness, here, too. As soon as you?re in Live, cued scenes and the clips, therein pulse green, slowly within the APC40 MK II?s own grid of buttons. And, to be honest, out of many of the controllers that I?ve looked at, I?d have to say that the way the LED default color assignments are set up would have to be one of my favorites. The default color assignments of the LEDs, for me, were very helpful in guiding me in to trying new things, with the APC 40 MKII.

Just intuitive in every single step and way.
