Uploading samples

Hey, i’ve been loving playing with this opz but need to start adding in samples. downloaded some stuff from op1.fun and dropped them into the sample folders (1 -kick) but when I power back up they aren’t there. They don’t seem to be winding up in the rejected bin either. I’ve upgraded to the latest firmware but still not working. Would appreciate some help


What does the Op-1 show when you restart?
The drum sample length is not longer than 12 sec and it is aiff, right?
