First of all, qjackctl doesn't save its own configuration in ~/.jackdrc 
but rather in ~/.qt/qjackctlrc .

The .jackdrc file is used (only) when you set your environment 
accordingly to let jackd start automatically when some client gets 
launched, outside of qjackctl. Can't remember which precise environment 
variables are of value ATM. Maybe something like $JACK_START_SERVER, or 
something. Please check jackd man page ...

The qjackctl/Setup/Misc/Save option is only there for the convenience of 
   .jackdrc be in sync with the qjackctl settings. Reasons why this is 
not your case is not very clear to me.

In fact, qjackctl just writes (never reads) $HOME/.jackdrc whenever the 
jackd is started under its control (and Setup/Misc/Save option is on). 
Be sure you're looking under the same user $HOME directory that you're 
running qjackctl. Check for write permissions, etc. You can try to 
remove your .jackdrc file and see what qjackctl writes right after that, 
if anything at all.

I don't know a thing about BiaB, even less about wine. What I know is 
that qjackctl only cares about ALSA Sequencer client ports. No matter 
for old-fashioned OSS (/dev/midi*) stuff. However, if that's precisely 
the case,q you probably want to know that ALSA's snd-virmidi module can 
be of some help here.

Bye.
