Mac OS X: Select your chosen playback (output) device from the Playback Device menu. Select your chosen record
(input) device from the Record Device menu.
Windows: Select your device for audio input and output from the Audio Device menu.
3. Some devices offer a selection of configuration options. If your connected device has those controls, you can click on the
[Control Panel] button next to the device selection drop-down menu and make your changes within the device’s control panel.
If your device does not offer these options, the Control Panel button is greyed out.
4. Set Device Block Size to fit your needs. Lower settings minimize latency, which is useful when tracking. Higher settings bring
more latency, but give you additional processing power for effects and instrument plug-ins. Generally, you want to pick the
lowest block size that still lets your system perform correctly. If you require higher performance but want to keep latency low,
you can increase the level of Dropout Protection and employ Low-Latency Monitoring.
5. When the aforementioned settings are selected, your system’s current total input and output latency, sample rate, and bit

Audio Dropout Protection and Low-Latency Monitoring
When you are working with a large amount of audio tracks and virtual instruments, computer performance can limit your capabilities.
You can increase the amount of buffer to help free up computer resources, but this traditionally comes at the cost of greater latency
(or delay) when monitoring audio inputs or playing virtual instruments. Set the buffer too low, and audio dropouts and glitches can
occur.
To remedy this, Studio One features Audio Dropout Protection and an advanced Native Low-Latency Monitoring system. Under this
system, the tasks of audio playback and monitoring of audio inputs and virtual instruments are handled as separate processes. This,
in effect, lets you use a large processing buffer to handle heavy audio playback and effects processing tasks, while keeping latency
low

Block Size Vs. Process Block Size
The latency that you hear when monitoring audio inputs or playing virtual instruments is based primarily on the Device Block Size
that you specify in the Studio One/Options/Audio Setup/Audio Device (Mac OS X: Preferences/Audio Setup/Audio Device) window.
For the lowest latency, Device Block Size should be set to the lowest setting that provides the performance you need.
The Audio Dropout Protection system uses its own buffer for playback and processing of audio tracks, distinct from the Device Block
Size setting. The size of this buffer (also known as the Process Block Size) depends on the Dropout Protection level that you specify
in the Studio One/Options/Audio Setup/Processing (Mac OS X: Preferences/Audio Setup/Processing) window. If you use Native or
Hardware Low-Latency Monitoring, the Dropout Protection level has no effect on audible latency, though higher levels can affect the
responsiveness of onscreen meters and displays.
As long as the Process Block Size is larger than the Device Block Size you've specified, you have the option to use Native Low-
Latency Monitoring.
Monitoring Latencies
The Monitoring Latencies display shows you the latency values for audio inputs (round-trip, from input to output) and virtual
instruments, based on the current Device Block Size and Dropout Protection settings. The "Standard" column shows the latency for
the current settings if you choose not to use Low-Latency Monitoring, while the "Low Latency" column shows values for the Native
Low-Latency Monitoring system.
Plug-in Use with Native Low-Latency Monitoring
When monitoring an audio input or virtual instrument through the Native Low-Latency Monitoring system, any inserted FX on the
corresponding Channel continue to function and can be heard in real time, provided that they add 3 ms or less of latency.. Plug-ins

ative Low-Latency Monitoring. They begin functioning again when recording/monitoring mode is disengaged.
The following plug-in types and configurations are not supported on Channels that utilize Native Low-Latency monitoring:

1. Navigate to the Studio One/Options/Audio Setup/Processing (Mac OS X: Preferences/Audio Setup/Processing) settings
window.
2. Choose your desired level of protection from the Dropout Protection drop-down menu. The Process Block Size display shows
you the corresponding processing buffer size. If you want to use Native Low-Latency Monitoring, choose a Dropout Protection
level that sets the Process Block Size to a value that is higher than the Device Block Size you have selected.
3. For low-latency performance when playing virtual instruments, enable the "Enable low latency monitoring for instruments"
option. If you run into performance issues when using a virtual instrument with particularly high CPU usage, you may want to
disable this option.

a supported DSP-enabled audio interface, you have the choice to use its onboard Hardware Low Latency Monitoring
(and hardware DSP-based effects when available, as with the PreSonus Studio 192) for incoming audio inputs, or to use the
Native Low Latency Monitoring that Studio One provides. Enable "Use native low latency monitoring instead of onboard DSP"
to use Native Low-Latency Monitoring, or disable it to use Hardware Low-Latency Monitoring.
Note that when using Hardware Low-Latency Monitoring to monitor an audio input, Insert FX do not function on the
related Channel, since the audio input is being monitored before it reaches Studio One. If Insert FX are needed while
tracking, use Native Low-Latency Monitoring instead. To do this, navigate to Studio One/Options/Audio
Setup/Processing (Mac OS X: Preferences/Audio Setup/Processing) and enable the "Use native low-latency
monitoring instead of hardware monitoring" option.
Enabling Low-Latency Monitoring in the Console
Once you've configured your system to use Native or Hardware Low-Latency Monitoring, you can toggle low-latency monitoring on
and off for the Main output as well as any Cue Mix outputs you've specified, by clicking the Enable Low-Latency Monitoring button
("Z", short for Z-Mix) below the volume fader for the related output. When low-latency monitoring is disabled, the "Z" button goes

Precision
By default, Studio One’s process precision is set at Single (32-bit). If using Studio One Professional, you may choose double
precision (64-bit) from the Process Precision drop-down menu.
Supported Devices
Studio One supports most audio devices, including those that run on ASIO or WASAPI (Windows) or Core Audio (Mac OS X) drivers.
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.

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.
The configuration of the Audio I/O Setup is done within each Song, so that it is possible for each Song to have a separate I/O

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

In the Audio I/O Setup menu, there are two tabs: one for input configuration and one for output configuration. In each tab, a
Matrix Routing view shows the current configuration, with the vertical columns indicating hardware audio device channels
(hardware I/O) and the horizontal rows indicating created software I/O channels. Software I/O channels function as the input
sources and output destinations available to individual Tracks in Studio One

move Software I/O Channels
Click on the [Add (Mono)] or [Add (Stereo)] button to add an Input or Output Channel, depending on which tab you are currently
viewing. When a new channel is added, the next unassigned hardware inputs or outputs are assigned to the new channel by
default.
To remove any channel, click on the channel to select it and then click on the ]Remove] button. To rename any channel, double-
click on the name of the channel, type a new name, and press Enter. In order for software I/O changes to occur, be sure to click
Apply before exiting this menu.
Assigning Hardware I/O to Software I/O Channels
Hardware inputs and outputs are assigned to software I/O channels in a matrix router, which is a visual representation of the
routing. Software channels (mono and stereo) are each given a horizontal row, and hardware inputs and outputs are given
vertical columns. The points at which these rows and columns intersect represent potential connections, or routes, between the
hardware I/O and software I/O channels.
By default, Studio One creates three Input Channels: one stereo and two mono. These channels are labeled Input L+R (stereo),
Input L (mono), and Input R (mono). By default, the stereo Input Channel receives input from the first stereo hardware input pair
of your selected audio device. The two mono Channels receive input from the same stereo hardware input pair.
The Output Channel is labeled Main Out (stereo) and is routed by default to the first stereo hardware output pair of your selected
audio device.
To create a route between software I/O channels and hardware I/O, click on the empty square at the intersection of the desired
hardware input or output and the software channel input or output. A colored square appears with an M, L, or R label, indicating
whether the route is a mono route (M) or the left or right side of a stereo route (L or R).
While it is uncommon for Audio I/O Setup changes to be required in the middle of Song production, the audio I/O routing can be
changed at any time. However, you should be aware that routing changes affect all associated Tracks, possibly switching inputs
for audio Tracks, changing the hardware output for the Main Output, and so on.
When making new routes in the Audio I/O Setup menu, notice the meters to the left of the software I/O channels. By displaying
signal levels on each channel, these meters help you ensure that the appropriate routings have been made.
Default Device I/O Setup
We recommend that you create a default Audio I/O Setup that can be a starting point for all new Songs. This lets you immediately
begin working in your new Song, with little or no preliminary setup.
To do so, create software I/O channels for all of your audio device’s commonly used inputs and outputs and name them
appropriately. Then, click on the [Make Default] button in the Audio I/O Setup menu, and a pop-up window appears to confirm
that you wish to make the current I/O setup the default for new Songs. Click on Yes, and from that point forward, all new Songs
are created with this audio I/O setup.
Audition Channel
The Preview Player in the Browser and in the Import File menu uses the Audition channel for audio playback. Any stereo Output
Channel can be used as the Audition channel, allowing you to audition sounds from an output other than your main output.

External Devices: Keyboards, Instruments, and Control Surfaces. While each device type functions in a slightly different way,
there is one menu to add and configure any External Device. The menu can be found by navigating to Studio
One/Options/External Devices/Add Device (Mac OS X: Preferences/External Devices/Add Device).
Set Up MIDI Keyboards
A MIDI keyboard controller is a hardware MIDI device that is generally used for playing and controlling other MIDI devices, virtual
software instruments, and software parameters. In Studio One, these devices are referred to as Keyboards. Before recording a
performance with a Keyboard, the MIDI keyboard controller must first be set up in Studio One. Once a Keyboard is set up, it is

rnal Hardware Instruments
In Studio One, an External Instrument is an external MIDI hardware synthesizer, workstation, or other device that can generate or
manipulate sound. External instruments are set up globally and then are available for use in any Song.
To set up your Instrument, navigate to Studio One/Options/External Devices (Mac OS X: Preferences/External Devices) and
follow these steps:
1. In the Options/External Devices menu, click on the [Add...] button.
2. In the left-hand browser, choose your device from the predefined device list. Set this to New Instrument if you do not see
your device in the list. If set to New Instrument, you may wish to type in a Manufacturer Name and a Device Name in the
appropriate fields. This makes identifying your New Instrument easier.
3. Specify which MIDI channels to use to communicate with this Instrument. MIDI Channel 1 is selected by default. If you are
unsure of the appropriate MIDI channels to use, just leave this at the default setting.
4. Specify the device to which Studio One is sending MIDI and the device from which the software is receiving MIDI. Select
the appropriate MIDI device from the drop-down menu for Send To and (optionally) Receive From. It is likely your external
instrument is not connected directly to your computer. In this case, your external instrument must be physically connected
to another MIDI device (such as a MIDI interface) that does connect to your computer; you need to select the driver for
that device.

t if your instrument is also a controller (such as a keyboard workstation), you need to set it up twice. First, set it up as an
External Instrument without a Receive From selection, and then set it up as a Keyboard, without a Send To selection. This allows
the keyboard-controller section of the workstation to be used as a source for Instrument Tracks, while allowing the synthesizer
section to be used as an external instrument.
Set Up Control Surfaces
In Studio One, a Control Surface is a hardware device that includes transport controls, faders, and other specialized controls. The
control surface might use MIDI directly or via a special control layer such as Mackie Control.
To set up a Control Surface, do the following:
1. In the Options/External Devices menu (Mac OS X: Preferences/External Devices, click on the [Add...] button.
2. Choose your device from the predefined device list. Set this to New Control Surface if you do not see your device in the
list. If set to New Control Surface, you may wish to type in a Manufacturer Name and a Device Name in the appropriate
fields. This makes identifying the Control Surface easier.
3. Specify the device to which the Control Surface is sending and the device from which it is receiving via Studio One. Select
your MIDI device driver name from the drop-down menu for both Receive From and Send To.
4. You do not need to specify the MIDI channels your Control Surface should use, as control surfaces use alternative
protocols, such as Mackie Control, to communicate with Studio One.
5. Your Control Surface is now ready for use in Studio One.

surfaces appear under the Ungrouped tab. To place a surface in a group, select a Group tab, then click-and-drag the surface
from the Ungrouped area to the selected group area. To adjust the order of the grouped surfaces, click-and-drag them left or
right. Channels in the Console appear in order across the surfaces from left to right.
Up to four Groups can be created, to allow for mirroring of Channels across multiple surfaces. This is helpful if you have more
than one location in the studio where you wish to use control surfaces (e.g., an A room and B room or a control room and live
room).
Only supported and predefined Control Surfaces appear in the Placement window. User-defined devices do not appear in this
window.
Use Your Computer Keyboard as a MIDI Keyboard
You can use your regular QWERTY computer keyboard as a MIDI Keyboard to play virtual instruments and record musical data
in Studio One. To do this, add a new device in the Studio One/Options/External Devices/Add Device menu (Mac OS X:
Preferences/External Devices/Add Device), choosing the QWERTY Keyboard device from the PreSonus device folder.

double-clicking on it in the External panel of the Console. Any record-enabled Instrument Track then receives input from the
QWERTY Keyboard, as shown in the QWERTY Keyboard device interface. Your keyboard only transmits data to Instrument
Tracks while the QWERTY Keyboard device interface is open.
Using the PreSonus FaderPort
If you have a PreSonus FaderPort connected to a computer running Mac OS X or Microsoft Windows, Studio One automatically
recognizes it and configure it for use. Just open a Song or Project to use the FaderPort immediately.
Reconnect Devices
In most applications, when MIDI devices become disconnected while the application is running, you usually have to restart the
application, and the software may crash. In contrast, if an external MIDI device becomes disconnected while Studio One is
running with a Song or Project open, the device can be reconnected without restarting Studio One.
If this occurs, navigate to Studio One/Options/External Devices (Mac OS X: Preferences/External Devices) and click on
Reconnect at the bottom of the menu. Then reconnect your devices and click OK. The devices should now work normally in
Studio One.
If an external device is not present when Studio One is started—for instance, if you’re traveling and don’t have some of your gear
with you— the application still runs normally. You should see a warning message that makes you aware of the situation. If your
setup frequently changes, you may wish to turn off this warning message by disengaging the Notify Me If Devices Are
Unavailable When Studio One Starts option.
Later, when you start Studio One with the device connected to your computer, Studio One recognizes the device automatically,
and it can be used exactly as before, with no further setup required.

Managing Y
our Content
Content m
anagement and file management can become unwieldy when working with digital audio workstation software due to
the sheer volume of loops, effects, song ideas, individual tracks, and so on. In Studio One, you only need to locate your
preexisting content once, after which all of the locations are remembered. Any content you create using Studio One is similarly
m
anaged. In Studio One, your content is kept in distinct categories.
The following describes the process of managing your content using the Studio One/Options/Locations (Mac OS X:
Preferences/Locations) menu.
User Data
Any content you create using Studio One is automatically stored in the location you specify. This includes Songs, Projects,
Effects Presets, and all of the files these categories contain. All of your creative output can be logically organized and kept in a
single place, which makes future location and backup a breeze.
When creating a new Song or Project, the User Data folder is the default save location. While we recommend using this location,
you can specify any save location when creating any new Song or Project.
Engage the Auto Save Documents option to automatically save any open document at a specified interval of time.
Engage the Ask to Copy External Files when Saving Song feature to be given the option to consolidate any outside files to the
central data folder when saving a Song.
File Types
All supported file extensions are listed in the Studio One/Options/Locations/File Types (Mac OS X: Preferences/Locations/File
Types) menu. Only these supported file types are displayed in the Browser.
It is possible to add file extensions to this list by clicking on the [Add...] button. In the pop-up menu, you can choose an icon, enter
the file extension, and provide a description for the file type. Select a user-added extension from the list and click on Remove to
remove it.
Sound Sets
Preconfigured packages of loops and samples are bundled with Studio One. The Browser’s Sound Sets folder makes finding this
content quick and easy. These packages also contain information about each content vendor, which is displayed in the Browser
when a package is selected. Click on the Visit Website link in the Browser for more information about the vendor and the content
they supply.
Instrument Library
Studio One includes a native virtual instrument called Presence XT that utilizes a cross-platform sample library format, as well as
standard libraries in Giga, EXS, Kontakt (version 4 and below), and Sound Font (SF2 and SFZ) formats. Using the Instrument
Library function, you can tell Studio One where your sound sets are located, giving you access to them as presets in Presence
XT.
To add sound library file locations to your Instrument Library, in the Studio One/Options/Locations/Instrument Library (Mac OS X:
Preferences/Locations/Instrument Library) menu, click on the [Add...] button and specify a file location, then click OK. You can
specify as many locations as you need.
For more information on the Presence XT built-in virtual instrument, refer to the Presence XT section.

Studio One fails to find certain plug-ins, adding them is easy.
To add any missing VST plug-ins, navigate to the Studio One/Options/Locations/VST Plug-ins (Mac OS X:
Preferences/Locations/VST Plug-ins) menu and click on the [Add...] button, then specify a location and click OK. You can also
drag-and-drop any folder from the Explorer/Finder into the Locations list. Studio One then scans these locations at startup,
including searching for new plug-ins you’ve added. You can always add more locations if needed.
AU, VST 3, and ReWire-enabled plug-ins and applications have their own pre-set file path in the OS and do not have to be
located manually.
Failed Plug-ins
If any plug-in fails to start correctly when scanned at startup, a notice appears next to its name in the startup message list, and a
warning message is shown. If the plug-in continues to fail at startup—for instance, if it is not authorized correctly or a required
iLok key is not present—Studio One puts the plug-in in a blacklist and ignores it at startup from that point on.
To reset this blacklist and force Studio One to scan missing plug-ins again at startup, navigate to Studio
One/Options/Locations/VST Plug-ins (Mac OS X: Preferences/Locations/VST Plug-ins) and click on [Reset Blacklist]. The next
time you start Studio One, the previously blacklisted plug-ins are scanned again. If the issues that caused the plug-ins to fail the
scan have been resolved, the plug-ins are made available.
VST Format Support
Studio One Producer and Professional support VST 2.4 (including VSTXML for hierarchical parameter structure) and VST 3.

Sample Rate
“Sample rate” refers to the rate at which incoming analog audio is sampled per second during conversion to a digital signal. The
most common setting is the standard sample rate for audio CDs: 44.1 kHz, meaning 44,100 samples per second.
The Studio One sample rate should match the sample rate of your audio interface, so by default, the sample rate is set to your
current audio interface’s sample rate, and changing this setting initiates a sample rate change in that device. If the sample rates
don’t match, Studio One resamples all audio files to match the sample rate of the hardware, but this can cause performance

problems and should be avoided. Studio One is capable of recording at any sample rate your hardware audio device offers.
Not all devices allow a third-party software application to change the hardware sample rate. The desired sample rate should be
set before creating a New Song.
File size is directly proportional to the sample rate and resolution. The higher the sample rate and resolution, the larger the
resulting audio file is.
Resolution
“Resolution” refers to the bit depth of digital audio, which is related to the audio’s dynamic range. Standard CD audio has a 16-bit
resolution, which results in roughly 96 dB of dynamic range. Thus, with “CD-quality” audio, the difference between the quietest
and loudest sounds possible is 96 dB. The most common resolution setting in professional recording is 24-bit, which produces a
dynamic range of approximately 144 dB.
Studio One can record audio with 16, 24, or 32-bit (floating point) resolution. Which resolution to use is a matter of preference. If
you are unfamiliar with these concepts, try experimenting with recording at each resolution and comparing your results.

However, if you do not intend to work with Timestretching in your Song and want to ensure that nothing gets timestretched
automatically by mistake, make sure this option is deselected.
Only audio files with encoded tempo information are stretched automatically with this option engaged. Studio One remembers
tempo information you specify within the Inspector view for any audio file.
