You can create an 'Aggregate Device' to glue the devices together by
following the steps in this link.
If you are trying to use soundflower
you need to create an
'Aggregate Device' for both directions, you can not mix your soundcard drivers and
soundflower in the same
'Aggregate Device'. Once you have done this the

'Aggregate Device' is not enough, it also
needs to be set as the default device to use in the 'Audio Midi Setup' of
the mac control panel.
For routing MIDI from another
VFX you can use the IAC feature that is built into the MAC
OS. Be sure to disable any MIDI drivers that send
MIDI from the

By setting up
soundflower you can use the
VFX application like a
Rewire application and
use plugins that normally only run on a PC.
