These review questions are all wrong for this piece of equiptment
Is it responsive? Yes and no. The keys are great but the drum pads are stiff and you really gottta pound them, which is infamously common with Akai devices. It can be upgraded to more sensitive pads. Does it sound realistic? This is a MIDI controller, so thats like asking if a ventriloquist dummy sounds like the guy making it talk. It sounds as realistic or indane or cool or lame as the module, synth, whatever you gave it plugged into. It is portable? Well...its compact, so its not cumbersome to lug around, but it doesnt accept batteries and it heeds a brain to make it work. So again, these are not the right questions to ask about a midi controller.
Bottom line: I got this cheap because it was used and thefe was more wrong with it than the seller disclosed. It does what I need it to do but not without several managable caveats. If you can get this for less than $100 used then youre in good shape. Its upgradable, somewhat intuitive if you know the ropes and theyre common as they come so theres repair parts out there. It doesnt have a power button or switch, you just plug it in which is pretty lame. I dont think its worth the pruce of one new, but Im very happy with it having ended up paying around $40 for mine because the USB doesnt work and a couple buttons sometimes dont work. Both of these arent big issues since I only use it for MIDI and theres work arounds to use other buttons or knobs i stead of the faulty ones. So find one used and a little beat up that still does everything you need it to, get it for less than $100 and repair/upgrade later. Thats my advice and my review.
