hm, too bad. Same is true for the external, I guess?

yep. vanilla patches are the only option for that ... but when it comes to 1-sample feedback without block~ 1, the only options are the filter objects (rpole~ etc.). i'm honestly not completely sure if this dynamic smoothing here could be achieved in some other way (like obtaining x[n-1] via rzero_rev~ 0) - but i don't think so.
