I'd like to use [pattr] object with Matrix values in order to recall last values when closing/opening Live Set. (I've checked "Parameter Mode Enable".
In my example below, it seems to keep only the last value.
Try the patch below, what you patched would only remember the last value the matrix sent to its outlet. With objects that use their outlet to send the complete state it would work, but the bindto outlet is the way to go in most cases (needs only one cable...)
