Bc2000 (for the BCF2000 & BCR2000)

Hi everyone, 

I'm trying to set my BCR-2000 up as a MIDI Interface, because my Pulsar is broken :(

now I'm encountering the problem, that if I send straight 16th notes to my synthie, it does a random shuffle effect. It' like I programmed something like vocal house, but I swear I didnt :)

I'm using a IBM ThinkPad running XP Professional and Ableton Live 8. The BCR is the only USB Device connected.
You only notice slight glitches, sometimes it forgets to play a note, it's not working.
Even If I only play one pattern and leave the Computer by itself, it randomly happens.

So, if anyone has any suggestions, it would be nice to hear from you :)

cheers
