Inputs 1-2 will give you input from your Snowball mic. Your aggregate device is now an available device in the Core Audio menu of your Audio Devices. In Logic Pro, open the Audio Preferences menu: Logic Pro > Preferences > Audio. Click Done and close the Audio MIDI Setup. You can use the cardioid with -10dB pad setting to capture loud sounds. The most common for recording is cardioid, of which the Snowball Ice supports. You might want to rename your aggregate devices to something that’s easily recognizable. The Blue Snowball has three types of polar patterns: cardioid, omnidirectional, and cardioid with -10dB pad. If you use your Snowball away from your regular soundcard, like when you’re on the road, you may also want to create another aggregate device with your output set to the “Built-In Output” and input set to your Snowball. Select your Blue Snowball mic as the input and your regular soundcard as the output. In OS X 10.7 (Lion), click the + at the bottom of the Audio Devices window and choose Create Aggregate Device.Ĭlick on the “+” to add an aggregate device. Open Audio MIDI setup in your Applications/Utilities folder and from the Audio menu, select Open Aggregate Device Editor. If you’re stuck trying to get Logic Pro to recognize your Blue Snowball USB microphone, there’s a simple solution.
