Has anyone tried using Jack OS X or Soundflower in conjunction with a Tascam FW-1884? I have been trying to use Jack to connect between Max/MSP and Cubase, but when I try to connect them in the Jack connections manager, Cubase disappears from the list as soon as I try to click on it. It looks as though the Tascam driver is automatically taking control or something. Is there a workaround, or do I have do disconnect the Tascam in order to use Jack?
I had similar problems with Soundflower. I managed to route audio from Max/MSP to Cubase, only I couldn't monitor the signal via the Tascam.
Any help much appreciated.

have you set jack to use the Tascam as its driver, and the other apps to use Jack as their driver? I have never really used cubase, but i send audio between MaxMSP and Logic all the time with Jack.
