Help looping sample...

aight so i got this sample like 4 bars long i added a drum n bass line. i wanna loop it to be like 12 bars...but whenever the 4 or 8 ends it sounds really bad when it loops...any tips as to how to make it flow better... thanks

trim it, or pitch it, or time stretch it.. have the decay to be 0 instead of the default 5....

Check the "gaps in loops" topic in the forum. I already gave some advice to somebody else about that. I hope it'll be helpful

peace
