HELLO.
I would like to do something with logic Pro 8 that i used to do easily with Digital Performer > Make it work with 2 Audio interfaces.
The fact is that i have 2 Motu Interfaces and i would like to use both of them in the same time.
And... I love to work with "soundflower", the virtual sound interface that allow me to make audio busses beween software. This way i can record in logic, a sound that is made by an other application. Very usefull.
So , I really don't know in LOGIC PRO 8 how to select 2 interfaces in the same time.

Anyone ?

THANX

OK. I found the solution. I have to make an "aggregate device" in the "audio midi setup" on the OS.
This way, i can create a new virtual interface made with more that 1 interface.
In logic, i can see this new virutal interface, and i have all the i/O i wanted.

:-)

Go into your Application Folder, then to your Utilities Folder, then to Audio MIDI Setup and create an aggregate Audio device. What this is is essentially a way of putting multiple Audio Sources together.

It pretty easy to do!

I bought the Duet to use with my Aluminum iMac and Logic Studio 8 and have had zero problems with the unit. The interface is very streamlined so you have to get used to using a single, multi-function knob for everything. The quality of conversion between analog and digital is head and shoulders above anything else near this price level. It sounds as good as units costing 3 times as much due to the designers' emphasis on quality sound. To get the high quality conversion at this price you are limited to the line outputs and headphone output levels being permanently linked. Some people find this a drawback, so be aware before you buy if this feature is something that is a deal breaker for you. The small form factor is nice because as anyone with a home studio can attest to, space is not a luxury we have. I didn't pick this for its portability but as it is the size of a paperback book I can imagine it being very easy to tote around with a macbook/pro. 70-290 The included Maestro management software is straightforward and lets you set the unit up in seconds with a very easy to understand user interface. Configuring my iMac to use this as the audio input and output took less than a minute from reading the instructions. Making Logic label its mixer to match is equally simple. One thing I found convenient is how OSX lets you still use the iMac's built in speakers for the system alerts so that an error message gong sound isn't sent out through your 100watt studio monitors. You can set the output level of the system alerts separate from the duet's outputs. 70-640 The breakout cable is securely attached and the plugs are labeled with big, clear markings so changing hook-ups is easy. It has phantom power if your mics require it, which is set using Maestro. Most audio interfaces in this price range try to win you over with more I/O channels or other add-ons instead of making the best sound conversion. SY0-201 They trade quality for quantity with predictable results. Apogee decided on doing a simple 2 channel interface, a single physical control and top shelf A/D/A converters so the result is the best 2 channels you can get. When you want more channels without sacrificing quality then you can step up to their Ensemble line.
