Set Up Your Audio Device

Studio One automatically selects, from a list of devices installed on your computer, an audio
device to use for audio input and output. To select a different device, navigate to Studio
One/Options/Audio Setup (Mac OS X: Preferences/Options/Audio Setup).
Then follow these steps to configure your audio device for use in Studio One:
1 Select a device from the Audio Device drop-down menu under the Studio
One/Options/Audio Setup (Mac OS X: Preferences/Options/Audio Setup) menu.
2 If you wish to change the settings for the selected device, click on the Control Panel
button next to the device-selection drop-down menu and make your changes within
the device's control panel.
3 When using a Core Audio device, you will see a Device Block Size setting. The Device
Block Size is the audio device's buffer size, which has a direct impact on your audio
device's performance. You can increase or decrease the Device Block Size by sliding
the horizontal fader left or right. The appropriate setting depends upon your specific
use of Studio One. For more on this refer to the
Power section of the "Mixing" chapter.
4 In the Windows version of Studio One, Internal Block Size can be locked to the Device
Block Size by checking the Lock box (checked by default). The Internal Block Size is the
software buffer size, which will have a direct impact on your computer system and on
Studio One's performance. For more on this refer the Maximizing Computer
Processing Power section of the "Mixing" chapter.
If unlocked, the Internal Block Size can be selected from a drop-down menu. If you are
•
unsure of the best setting, leave Internal Block Size locked to Device Block Size.
For hardware-driven effects and virtual instruments, such as the TC Electronic
•
PowerCore and Universal Audio UAD card, locking the Internal Block Size of your
Audio Device is critical to ensure proper operation.
