  Here we show that, given a finite homological system $({\cal
P},\leq,\{\Delta_u\}_{u\in {\cal P}})$ for a finite-dimensional algebra
$\Lambda$ over an algebraically closed field, the category ${\cal F}(\Delta)$
of $\Delta$-filtered modules is tame if and only if, for any $d\in \mathbb{N}$,
there are only finitely many isomorphism classes of generic $\Lambda$-modules
adapted to ${\cal F}(\Delta)$ with endolength $d$. We study the relationship
between these generic modules and one-parameter families of indecomposables in
${\cal F}(\Delta)$. This study applies in particular to the category of
filtered by standard modules for standardly stratified algebras.
