hi, this is a not so important thing, but took me some time of searching for the error: the reference-patch 16.morearrays has a help for "setting the bounds rectangle" which says ;array99 bounds 0 -2 10 2 but then the y-axis is flipped (-2 on the top). maybe this has changed for newer pd-versions? it should be ;array99 bounds 0 2 10 -2. sme.
