I have a decent Shure mic hooked up to my Mac via a Lexicon Alpha device. I've set up the Aggregate Device via the Audio/MIDI Setup and the whole thing works fine with Logic Pro, but what I'd REALLY like to do is get that same setup working through Pd.

I have the [adc~] hooked up to a simple distortion patch, and from there it works just fine with the built-in mic, but I can't for the life of me get it working with my good mic.

Help?

My plan is to write a patch that'll distort and effect an English Horn solo in real time. Hopefully once I get this technical issue out of the way it'll be smooth-ish sailing the rest of the way.

Thanks!

you have to go to audio settings and select Lexicon Alpha as the audio input device

and I have, but it's still only accepting sound from the built-in mic. I'm pretty sure I set up the Aggregate Device correctly… I mean… it works in Logic…

Might it have to do with the [adc~ ] object? Or somethin' else? I'm quite new at this whole "Pd" thing, thanks for your patience.

Are you setting the correct channel argument set for [adc~]? i.e., for channel two you'd want [adc~ 2], for three and four [adc~ 3 4], etc. It defaults to one and two, so [adc~] = [adc~ 1 2].

I'm pretty sure I'm setting it correctly. I have the device set as the main audio in, so wouldn't that be just the default input of 1 & 2? I'll do some more messing with it when I get home tonight.

When you say you've set the audio input settings do you mean in the operating system (through the settings program on OS X) or do you mean through PD (PD->Preferences->Audio Settings)?

Because whatever you set in the former will be ignored by PD, only the latter matters.

ah-ha!! I didn't realize that Pd totally ignores the OS X audio settings! Wonderful, it's working for me now. Thanks a bunch to everyone who helped!
