EDIT: I’d noticed this first when using a looped sample. Actually it happens with any gated sound. Disaster.
Loop up a sample. Apply Gate. Play in a pattern. Add some drum elements.
EDIT: This seems to only happen if you have at least 3 more tracks in the pattern.
Set the filter up for override recording. Hold your Pad containing the Gated loop and adjust filter with record enabled. After a bar or 2 the values in the pattern get overwritten with 1 long sustained note. Pattern gone. Life is hard.
