Hey,
no problem for me to add it to wslib. would be a pleasure :-)
I am unsure on how to get the EQ-stuff properly to work; fiddled a
bit with SynthDef:wrap, but ended building this Pseudo-Ugen with
the predefined control name. Not really an option, I guess.
Using Busses is way cooler, but unfortunately incompatible with how
I use JITLib.
One solution would be to add a controlName slot to BFilterChainGUI
that specify the control name that controls the BFilterChain UGen,
which then should have just nirmal inputs instead of a named control.
It would also be cool (but completely unrelated to the above) to
use the GUI interface for effects in the MasterFX chain of the
SpeakersCorner quark.
for litlib style eq flexibility, maybe try ProxyChain?
