First, bootlegs are illegal and any sort of related question to them on FP is considered a "no-no," so please just buy your software, then you don't have to ask a dumb question like "should I buy reason instead of using this bootleg that doesn't work all the way."
The reason it doesn't work is because YOU didn't buy it and INSTALL it off the MANUFACTUERS CD. This is why you have problems.
Having the program direct from the company also allows you access to online services to registered members, for most software.
Also, to fuquan, Audition and WaveLab DO NOT chop anything for you like you said, but YOU CAN make your own chops with them.
Recycle & Beatslicer AUTOMATICALLY chop/slice samples for you.
To chop a sample and send it to Reason, you need Recycle (though I think beatslicer may have a file format that works in Reason, not sure).
And all you need is Reason, Trigger Finger (or Akai MPD16 if you want the MPC pads), and Recycle to chop. Other than that, a sequencing program.
If you want to use the MPC 1K, its all that stuff in one, but its a bit more difficult to get it to work for you, since you are limited by menus that you have to navigate.
This is about the only drawback, plus they left out the timestretch and reverse features, key factors in sampling.
Those 3 reasons are reason enough for me to not even mess with a 1K. I'd suggest a 2000XL or 2500XL.
