I am working on a sketch that requires a line in but I would like to use an external microphone rather than my internal mic built into the mac. Using Minim and STT.

I am finding problems selecting a mixer within my own sketch but it will select fine in the minim example.

Through running my external mic through JackPilot, it can pick it up and select it but when applied to my own sketch it doesn't read it.

Is there any simple way to get the mic to register on the mac for processing without defaulting back to the built in mic? 

(I have tried almost everything from changing system preferences to using many different audio servers)

Thanks
