Pattrstorage "by default"

Howdy folks. It's been a second since I last stopped in, hope all are well.

Consider the following patcher. My goal is to create a system that writes a pattrstorage preset programatically when (and only when) a number is sent to the flonum or a user chooses a value from the umenu. This presents an obvious problem; when a preset is recalled it is also stored, leading to a collision and a hard crash.

Putting a deferlow on the store message seemed to work in max, but not so much in live. The solution using a set message to prevent storage on recall does not crash, but somehow the wrong value always gets recorded for the umenu.

Many thanks in advance for any help
