Background
I haven't played drums nor percussion in nearly 20 years. I stopped
when I moved from a house in the countryside to an appartment where I
couldn't obviously play a 26" BD with 14,15,18&20" toms

. I also got involved in other interests. Now, I am in need of some midi drum pads to trigger samples for guide tracks of a record I am producing. The keyboard trick just won't do for Latin style. And I must admit, I sort of got into the grove of hitting things again.
The need now
As I mentioned, I need some decent quality pads that I can play both
with sticks and bare hands. The pads should be able to output Midi to
record in Logic Pro. I have decent collection of samples already, plus some "vintage" samplers at my disposal.
The lucky stroke
As I was wondering around music shops today in my quest for an
affordable Midi percussion device, I saw a DrumKat for around $350.00
with footpedals.
Question 1
I did some research on the web, but am not sure which model it is.
IIRC, it has 10 pads displayed in a mouse's head shape, it had 4
inputs for footswitches, 10 inputs for pads (no idea what they are
for, Midi I/O, a small display between the mouse's ears, was a black
painted metal box and the pads were greyish. So far I could only see
the DrumKat and the DK10 that had a resemblance with what I
*remebered* seeing. Could it be some older model?
Questions 2a - 2zz
The shop assistant, who has never seen one before and doesn't have a
clue how it works couldn't tell me much. He didn't have the power cord nor an external PSU which he said he will source tomorrow. Lets say he finds a PSU, how do I test it? What should I look for? What is likely to go wrong with these things? Were can I find a user manual for download? How do I find the version of software it is running?
Question 3
Does the DrumKat output sounds of its own, or is it just a midi
controller?
Questions 4-ad lib
Given what I have told you above, is this thing worth it. I mean not
just money-wise, but to what degree is it likely to fulfill my needs?
