PRESONUS S1 Artist 3.0 [18/307] Supported devices

Supported Devices

Studio One supports most audio devices, including ASIO, Core Audio (Mac OS X), and WASAPI (Windows) devices.

When using a WASAPI audio device in Windows, note that WASAPI offers Exclusive and Shared modes of operation. In

Exclusive mode, lower latency can be achieved, but other applications (such as Windows Media Player) cannot use the

audio device at the same time. Refer to the Windows Control Panel/Hardware and Sound/Sound to configure the options

for your WASAPI device.

Performance Monitor

When setting up your audio device (specifically when determining appropriate Internal or Device Block Size, or selecting

Single or Double Process Precision), you should take into account the related performance demands on your computer.

Open the Performance Monitor by selecting it from the View menu, or by clicking on the [Performance] button in the

Transport. This monitor displays the current relative overall CPU and disk performance, as well as the performance of

instruments and automation.

When these meters approach or reach the top of their range, you may need to consider altering your audio device settings

(or changing the Song or Project) to avoid audible clicks and pops or possible instability. For instance, it is common to lower

the Device and/or Internal Block Size while recording to keep monitoring latency low but then to increase Block Size while

mixing to provide as much CPU headroom as possible for effects processing.

If any playback issues are encountered with third-party virtual instrument or effect plug-ins that have their own

multiprocessor support implementation (e.g., NI Kontakt, FL Studio), it is recommended that this support be disabled in

the plug-ins. In this case, Studio One manages all processor scheduling.

Audio Device Input/Output Setup

Software I/O Channels

In most recording applications, audio Tracks directly use your hardware audio device’s channels. In Studio One, there is a

layer of software I/O (input and output) channels between your hardware audio device channels and your Tracks. This

setup affords many advantages over the traditional method.

For instance, let’s say you produce a Song in your studio, using a multi-channel interface, then take your Song file to your

friend’s studio, where you use a different audio interface. Simply connect your friend’s hardware audio device channels to

the correct software I/O channels. When you get back to your studio, the original I/O configuration for the Song is

automatically loaded for you, as if you never left. You can do the same thing if you need to open the Song on your laptop

using its built-in audio hardware.

This is possible because Studio One stores I/O configurations with your Song, per computer and per audio device driver,

ensuring that your Song remains highly portable and is never “broken” by changing audio devices.

Audio I/O Setup Menu

Each Track in a Song receives a signal from an input source and routes to an output destination. The input sources and

output destinations made available to each Track are determined by the software I/O channel configuration created in the

Audio I/O Setup menu. To view this menu and set up a default I/O configuration for each Song, create a new Song by

clicking on Create New Song in the Start Page and navigate to Song/Song Setup/Audio I/O Setup.
