I finally just got my new machinedrum uw (from factory direct)and 
after what seemed like a long wait,i am dissapointed, as it is 
defective. First of all, one of the drum buttons has some sort of 
hang up or catching problem which prevents it from functioning as 
smoothly as the other buttons. 
The other problem is that when i try to play the drum buttons 
rhythmically to record a beat into live recording, they randomly will 
double trigger the drum sounds(problem happens with all buttons). 
This throws off the beat and is completely unacceptable for a $1700 
drum machine! I read a couple posts from 2004 where someone asked 
about the same issue. Somebody replied saying that it is basically 
normal. I have to disagree with that. In all my experience with 
hardware, it is NOT normal. Also, it is not any kind of a "bounce" 
that is happening. When the problem occurs, what actually happens is 
that when the button is pressed down, it triggers once. Then, when it 
is let up, it triggers again. I once had an older roland drum machine 
with the exact same problem, but my friend who had the exact same 
drum machine did not have this problem. I replaced all the tactile 
buttons on that drum machine with replacements from the factory and 
still had the exact same problem. That whole experience made me 
realize that it had to be an electronic problem instead of a 
mechanical problem.

What i really need now, is for some people to PLEASE help me out by 
playing about 12 meassures(or more)at different speeds of a beat 
manually on your machinedrum and tell me if you have any double 
triggering happening. I really need to find out if this is normal 
behaviour in the machinedrum, or if i got a bad one. I do not want to 
settle for a unit that may have worse problems in the future. I have 
had a LOT of bad luck with buying hardware in the past. I am almost 
ready to completely go the software/midi controller route. I mean, 
$1700 is ALOT of money for something like a machinedrum, and it 
should be a solid piece of gear. I just can not believe how they 
seemed to have cut corners on the knobs and buttons(in a way, those 
should be the most high quality parts on the machine, as they are 
actually "USED" the most! The reason a person would spend so much on 
just a drum machine, is for the HARDWARE interface. Thanks for your 
time.
