Thanks, Gilberto. Even with the d_filter.c being essentially synonymous 
with pd vanilla (latest version), the problem apparently persists. I am 
not sure why. Essentially, the behavior is the same in both the latest 
version of pd vanilla and the one we currently have in pd-l2ork. Did you 
see it behave differently in vanilla? If so, what version were you using 
and can you please create a video of that version running the same patch?
