IK Modo Bass is on sale for $29.99
The great thing about their basses is they are physically modeled. So (as far as I know) they do not use much ram.
I am happy with it.
Okay, I bought it.
Unfortunately it doe not work in logi , only in Rosetta mode.
How about in Gig Performer?
in Gigperformer it works fine!
I tried to send it to logic via Relayers but didnt suceed yet.
Strange. I would think plenty of Logic users use it.
The receiving Relayer instance doesn’t care what the plugin is in the sending instance. If there is signal going out, then signal will be received. ( so long as it is configured correctly)
I just dont have any experience with relayer-routing 
I Tried to get support,
but still no answer from ikmultimedia support since one week ago.
Thank you for the comment, and the link.
just solved the relayer-problem,
the problem was not matching sample freqs. between gig performer and logic,
which unfortunately always automatically reset to their old values.
so just a my user fault, it is working now!
