For how long have you been using it?
1 week. I struggled at first. Driver to install mac (poorly used), it will need the latest version of Live 7. Once installed all bingo! The machine lights up and opens our eyes. Plastoc but a little good for the price it is running. The knobs are very nice under the fingers.

What thing do you like most/least about it?
The +: Its direct integration with live, happiness! Super fun, there is a touch interface which opens the possibilities of the software.
Logic and its versatility with the Automap software is just huge for MIDI with the acquisition of software other than Live.
A priori there is a version of the software that exists for iphone / ipod touch.
A touch controller with a more Ipad instead one can dream of a tactile surface that handles extra comfortable automap when other software ...
The - I do not know yet ...
Did you try many other models before getting this one?
A CPU 33 that I keep for the use of faders and knobs ...
With both there is a sort of mini APC40 most versatile for my taste ...
I may be falling for a remote zero SL to be in line with Novation automap pro and my ipod.

What is your opinion about the value for the price?
Very correct

Knowing what you know now, would you make the same choice? ...
Certainly ...
