i have a tiny bit of beat marked out... when i loop it, it sounds like a full beat with a hi hat and a a kick, but when i take it off loop you don't hear these... something really weird going on here.

i've noticed before that sometimes the 303 shoots beyond the end point on a sample that's supposed to loop - it'll play beyond the end point and later start again at the start point... and does this every couple of cycles.

i swear i'm not smoking! my 303 must be bewitched.

Happens to me all the time. It seems to happen to me mostly when I over-use the mark button to make glitches. Nothing to really worry about, just one of those glitches that occur when you push the 303 a little hard.

It also happens when I try to record something within that is looped.

yep same here. anyway good to know my 303 is not crazier than others' : P
