I’m surprised at myself for not being able to sort this out after a day’s poking and proding. I’m trying to mix two system audio channels — the external mic and iTunes — and then be able to monitor the mix. I’ve lost myself in the baroque Soundflower configurations and basically got nowhere. I’m able to get Max/MSP to hear my audio — but I can’t monitor it through the headphones or internal speakers. I’ve configured all kinds of *Aggregate Devices and none will let me monitor the output. Seems like it should be simple. I mean — Max/MSP hears the mix..but it won’t output it. And the DSP windows won’t let me (I’m on an MBP 10.6.3, Intel Core 2 Duo) configure the *Playthrough option.
Basically I want to be able to mix a couple of processed sources, or voiceover, and have it actually go somewhere that I or anyone else could actually listen to live — rather than just get dropped on the floor.
I have a similar problem using Jack Router, even if you route your audio to dac~. Once I route iTunes and the "system" captures (internal mic) into Max, there’s no way to route the Max outs to the "system" outs. When I run my Firebox, no problem–all of the outs are accessible in Jack, but I can’t pull any audio from the internal mic.
I’ve got an MBP 10.5.8, Intel Core 2 duo also, and I wonder if there’s no separating the internal input and output.
