In this section we provide a few steps to help you quickly get UVI Workstation up and running. UVI Workstation can be used as a stand-alone application or as a plug-in inserted in a host sequencer. The steps below assume that your

MIDI/Audio system is configured correctly and includes a MIDI device for transmitting MIDI data, and an audio monitoring option to hear the sound.

UVI Workstation application

Load & Play

UVI Workstation includes the UVI Tutorial Set. This soundbank contains a basic selection of instruments and loops. Follow the steps below to load a sound.

1. Start UVI Workstation. Double-click or press the Browser icon

To open the stand-alone version, go to your Applications or Program folder and double-click on “UVI Workstation”. The software interface will be displayed. Select the menu File > Audio Settings to configure your audio and MIDI settings. Once you’ve confirmed your configuration connections, you’re ready to go.

UVI Workstation plug-in

2. Select a sound in the “UVI Tutorial Set”

(or any other UVI Soundbank located in the UVI Soundbanks folder)

3. Play a note on your MIDI device to trigger the sound. Note: make sure your

MIDI device is transmitting on the MIDI channel of the desired loaded part.

UVI Workstation can be used as a plug-in in host sequencers supporting AU, VST,

MAS and RTAS formats. To add UVI Workstation to your host sequencer project, simply select UVI Workstation from the virtual instrument list in your instrument track. Please refer to your host sequencer’s user manual for details on how to insert and use virtual instruments with your sequencer program.


The browser provides the ability to load sounds into a single part or multiple parts. In the “multi” page, part parameters such as Mute, Solo, Volume, Pan, etc. can also be edited while the browser is open.

Sound files and presets

There are two different types of objects that can be loaded into a part.

- UVI Instruments: Ready to play presets (pianos, violins, drum kits, etc.)

- Sound file: WAV/AIFF/REX and Apple Loops files.

Note: when you load a sound file, the sound is mapped across the keyboard.

When it’s a sliced sound (like REX files), the sound will automatically play with the browser’s default setting.

4. Repeat the steps above to load additional sounds.

Drag & Drop

UVI Workstation also allows you to import via the browser or by a drag & drop method. To load your own WAV/AIFF/REX and Apple Loops files via the drag & drop method, drag and drop the files from anywhere on your computer to the desired part in the part name, even in Single or Multi views.


UVI Workstation™ Manual


This section takes you through the process of creating your first sequence with the

UVI Workstation. The following screens are in the Multi mode.

1. Create your first sequence

1.1 Open UVI Workstation within your host software. Press the Multi button.

1.2 Let’s first check out the MIDI channel assignment for 3 parts. By default the parts are assigned from MIDI channel A1 to A8.

2.2 We can add more reverb to the Electric Piano by using the Mix slider.

2.3 Now let’s apply a Tremolo effect to our Electric Piano: click on “add FX”.

The FX Browser will display. Use the Browser to navigate to the folder named “07- Stereo & Amplitude”, than “01 - Tremolo”, and double-click on “Fast Tremolo” to load it.

1.3 Let’s load our first sound in part 1: double-click the word “Empty” to open UVI Workstation browser.

1.4 Click on “UVI Tutorial Set”. Use the multi-column browser to navigate to the folder “UVI Presets” and double-click on “Electric Piano” to load it.

3. Using a loop in a sequence

3.1 First, let’s replace our “Jazzy Drumkit” with the loop “100-Hip Hop Beat”.

Double-click on the part “Jazzy Drumkit” to open the Browser. Under the

“UVI Tutorial Set”, click “Loops-Rex” to reveal the loops.





Set up your MIDI host application so you can play on MIDI channel A1.

Now when you play, you should hear the Electric Piano. If not, check the part’s MIDI LED or refer to the chapter “Troubleshooting”.

Next, let’s load additional presets “Synth Bass & Synth” in part 2 and the “Jazzy Drumkit” in part 3 by simply selecting the respective part and double-clicking the desired preset in the Browser.

The drum part might be a little loud, and maybe the Electric Piano would sound better if moved a little to the left... Use the volume and pan controls for each part to improve the mix of this tutorial.

Double-click “100-Hip Hop Beat” to load it in this part. The “Jazzy

Drumkit” preset will be replaced, and you will hear the loop playing at your sequencer tempo. Click OK and then click Stop to stop playback.

3.2 To display the loop parameters, click on the icon to go on single page.

A cool feature of the UVI Workstation is the ability to drag and drop audio files directly into your host sequencer. Let’s check it out.

3.3 To import this loop into your host sequencer, simply click and hold the

“Drag & Drop” waveform icon in single page, and then drag and drop the icon (loop) into a track in your sequencer.

>>> You can now play and record through your host sequencer !

2. Effects and more

2.1 Select the “Electric Piano” part to display the FX section.

Note: In the following example, there are two effects currently inserted in the

Electric Piano preset . (“8 Band EQ” and “Simple Reverb”).

3.4 The loop has now been imported to your sequence. The audio you’ve imported can be manipulated like any other audio track in your host.


you are well on your way to becoming a UVI Workstation power user. :-)



Stand-alone operation

UVI Workstation can operate as a stand-alone instrument application, independent of a plug-in host. This option can turn your Mac or PC into a streamlined virtual instrument powerhouse with unlimited parts, disk streaming, multiple independent audio output pairs, and playback of a virtually unlimited library of instruments, loops and phrases. Stand-alone operation also allows you to:

- Play UVI Workstation directly from an external MIDI keyboard or other MIDI controller. Great for live performance!

- Use UVI Workstation as a comprehensive multi-timbral sound source for an external MIDI sequencer or MIDI-capable music software running on another computer.

- Use the UVI Workstation as a comprehensive multi-timbral sound source for

MIDI-capable music software that does not host 3rd-party instrument plug-ins, but that is running on the same computer as UVI Workstation.

Audio & MIDI Settings

The stand-alone version of UVI Workstation has a few basic audio and MIDI settings that can be found in the File > Audio Settings menu.

The Audio Settings preferences window provides the ability to configure the settings of any available audio hardware devices.

have a 3rd party audio interface installed or connected, and you do not see it in the output menu, be sure that you have correctly installed its driver and that it is otherwise functioning properly, independently of UVI Workstation.

Sample Rate

Choose the desired Sample Rate for playback. The choices in this menu are provided by your audio hardware driver, and the setting you choose here is the sample rate your hardware will be set to. 44.1 kHz is the standard rate for audio compact discs. UVI Workstation samples are provided in either 16-bit or 24-bit resolution at sample rates that range from 44.1kHz up to 192 kHz.

Note: If you choose to operate at a sample rate that is different from the actual samples (presets or loops) , the samples are sample-rate converted on the fly to match the rate you’ve chosen.

Audio Buffer Size

This setting is crucial for managing your computer’s processing resources. In general, settings of 256, 128 or 64 samples produce better latency performance than higher buffer settings.

Note: Lower buffer settings place higher demand on your CPU.

Active MIDI Inputs

This setting allows you to enable or disable the active MIDI inputs of your computer. If you have a 3rd party MIDI interface installed or connected, and you do not see it in the menu, be sure that you have correctly installed its driver and that it is otherwise functioning properly, independently of UVI Workstation.

Load & Save a Multi

The UVI Workstation Multi section offers a Load and Save feature that allows you to load and save multi configurations. Please refer to the chapter “Multi view” for more information.

Audio Device

Choose the desired audio hardware from the Audio Device output menu. For example, you could choose your computer’s built-in audio hardware. If you

The browser provides quick access to your library of sounds. Once a preset or sample (audio file) is located, it can be loaded into a part. You can open the browser in the Single and Multi pages.

- To open the browser: click on the «eye» browser icon

- Or double-click the current preset (or double-click the word Empty)

Browser in Single page

Loading a preset or a soundfile

1. Use the browser to navigate to the desired preset (or soundfile).

2. Double-click the preset name and click the “Ok” button at the bottom

> In Multi mode you can load sounds into parts without closing the browser.

> You can import your own audio files by simply drag and dropping them directly into a part. Remember that if you drag and drop from a location outside of UVI

Workstation (ex. from the Desktop), the file must remain in that location or it will become missing.


Browser in Multi page

Note: The display info option is only available in the browser on the Single page.


When the browser opens, you will see two tabs labeled Search and Soundbanks.

Simply click a tab’s disclosure triangle to view its contents. The “Soundbanks” tab automatically displays any authorized UVI Library.

You can browse through a soundbank just like a regular disk. UVI Workstation includes a tutorial sound library named “UVI Tutorial Set” that contains several

REX loops and UVI presets to get you started.

> You can use the arrow keys on your computer keyboard to navigate through the

Browser and select items.

- On the Search tab, select the category where you would like to search (Loops, Instruments or Sounds)

- Type your search and the browser will list the matching files.

You just have to (double-)click on the name to load it.

- If a library is not authorised or missing the volume will appear in red.

Auto Load / Auto Play / Original Tempo

“Auto Load”, “Auto Play”, and “Original Tempo” boxes are located at the bottom-left portion of the browser. “Auto Load” and “Auto Play” are enabled by default. When

“Auto Load” is toggled, selected loops are instantly loaded so you can preview the sound without exiting the browser.

“Auto Play” allows you to listen to loops as you select them. If the “Sync to Host” option is enabled, and your host software is currently playing back as you are browsing, selected loops will play in tempo with your music.

If you wish to listen to the currently selected loop in the Browser at its originally recorded tempo (during browsing only), toggle “Original Tempo”.

This option is useful for getting a sense of how the loop is supposed to sound and how it was originally recorded. Once you select the loop and press “Ok”, it will play the loop at the current sequence tempo.

Drag & Drop from the Browser to where you want

In addition to drag and dropping audio files to UVI Workstation, you can drag and drop a loop or a sound file directly from the UVI Workstation browser to any destination on your system: your host sequencer, the desktop, etc. You can even drag and drop directly to an UVI Workstation part.





3 4




UVI Workstation is a multi-timbral instrument that provides unlimited Parts. Parts are where you load Presets and can be accessed by clicking individual part slots

(as shown below). A Part is like a channel on a mixing console (or an instrument track in a DAW) and can contain its own preset and settings.


1. Adding / Deleting a Part

By default, a UVI Workstation session starts with 4 parts. You can add as many parts as you want by clicking on “+”. The new Part will be added after the last part on the list. To delete the currently selected part, press “-”


MIDI activity LED lights up when a part receives MIDI data.

3. VU-Meter

Next to the MIDI LED, it displays the volume of the part.

4. MIDI Assignment

UVI Workstation provides up to 64 MIDI channels, divided into four banks (A-D).

You can assign any MIDI channel for any part. Parts can also share a MIDI channel. To select a bank and a MIDI channel, click on the channel number of the part you want to assign, and then select a bank and a channel number.

-> New in V.2: omni mode, parts can now receive data from all midi channels.

(very useful when saving single instrument presets in GarageBand)

Important note:

4 MIDI banks are available in the MAS and RTAS versions of UVI Workstation.

However, the VST and Audio Unit standards do not support multiple banks of MIDI channels, but you can always open additional instances of UVI Workstation.

Tip to stack sounds:

If you assign multiple parts to the same MIDI channel you can easily create interesting and complex textures by stacking the presets: all parts that share the same

MIDI channel will play exactly at the same time with the same notes.




12. Load / Save / Clear Multi

Load and Save Multi use the standard Open File dialog.

Loading a Multi

> Be aware that your existing settings will be replaced by the loaded Multi, so if you want to preserve the current state, be sure to save it as a Multi before

What is a Multi ?

A Multi is a complete “snapshot” of the UVI Workstation. A Multi saves the entire engine’s state, including: all presets and effects that are currently loaded, as well as any tempo and loop settings. Using a Multi is a convenient way to transfer your

UVI Workstation settings to other projects, clients, colleagues, and even other host applications. Multis are platform independant.


UVI Workstation™ Manual


Managing your UVI Sound Banks

General - Global Tune

> Preferences section

Global tuning stage for UVI Workstation, it’s applied to the entire Multi, in addition to any other instrument-specific tuning adjustments that have been made. You could, for example, set the overall tuning to reference “A” at 442 Hz

(instead of 440 Hz).

If you’ve made changes to the global tuning of the UVI Workstation, you can

Alt-click the Tune value to return it to the default value of 440 Hz.

> If you have multiple UVI Workstation plug-ins instantiated in your host application, the global tune setting will affect each plug-in separately.


> Search paths: locations on your computer that are scanned for soundbanks when loading UVIWorksation :

- To add a search path, you can click on the search path bar and type in the path by hand. You can also click on the button on the right of the search path to browser for a new location.

- To remove a search path, click on it and hit the delete key.

> Indexed: enabling Indexed means that soundbanks in that search path will be indexed for the Search function in UVI Workstation’s browser.

> Recursive: when enabled, all the search path subfolders will be scanned for soundbanks. Otherwise only the top-level files will we scanned.

Warning: if you have many files and subfolders, this can significantly increase the startup time of UVIWorksation.

> Auto-mount: enabling it will automatically mount any soundbank file in the search path.

Global Memory & Volume

Disk streaming allows you to load programs that use a large amount of data, because rather than loading the entire sample set into RAM, the samples are read (streamed) from the hard disk as the program is being played.

The Streaming preferences pane provides settings to optimize streaming performance for your computer. In most cases the default settings will be ideal.

> Preload Time: is the amount of each sample preloaded into RAM when the program is first loaded. Lower values require less RAM overall, but increase the load on the host computer processor and the hard disk. Don’t use very small values because this causes many samples to be streamed unnecessarily.

In situations where a program consists of a large number of very large samples, and you have lots of extra RAM installed in your computer, a higher sample preload size can actually allow you to play more parts because the strain on the processor and hard disk will be lower.

> Ring Buffer Size: is the number of samples reserved for each voice after streaming has begun and the sample is being played. Lower values can sometimes help eliminate dropouts and similar artifacts, but lower values also increase the load on the host computer processor and the hard disk. Higher values reduce processor strain, but require more memory.

NOTE: Disk streaming performance can be affected by the speed of the hard disk, so the faster the hard disk is, the better.

> Memory indicator: show the RAM used by the whole UVI Workstation

> Volume: Overall volume setting for the entire UVI Workstation.

BPM screen

The “BPM” screen allows you to set the tempo of the overall UVI Workstation. To change the tempo of the UVI Workstation:

- Click and drag the BPM setting (the actual number value).

- Click directly on the BPM setting and type in a new value.

> Sync (to host application)

When “Sync” is on, the tempo of UVI Workstation is linked to the host tempo and the “BPM” screen displays the host’s current tempo. Use the tempo controls in the host to control the overall tempo of both the UVI Workstation and the host.

> “Sync” only works when using UVI Workstation as a plug-in in your host software.

When working in the Stand Alone version, the “Sync” setting is inactive.

TAP Tempo >

Simply click TAP in rythm to find the tempo you’re playing.

About matching grooves

As you can easily load and play tons of loops at the same time. In some cases, you may notice that loops may not be matching with other loops. When this happens it certainly because the underlying “grooves” of the loops may be different.

> In cases where loops are not matching with other loops, try using the “MAP” and

“MIDI Drag’n Drop” features as shown in the “Loop” chapter of this manual.

To use MIDI Learn:

1. Right-click any UVI Workstation control to assign a MIDI controller.

2. When the MIDI Learn dialog is displayed, send the desired MIDI controller data from your MIDI device. When you move the physical knob or slider on your MIDI controller, the controller data type is accepted and the window is closed.

> The MIDI controller type and the MIDI Channel assignment is then saved in the multi, or when you save your song in your host sequencer.

3. To remove a MIDI controller assignment, right-click the UVI Workstation control and press “Delete”.

Automation is assigned per part

When you assign a MIDI controller as described above, the control is connected to the currently selected part. This gives you the maximum amount of flexibility, allowing you to control multiple parts simultaneously.

UVI Workstation™ Manual


UVI Workstation offers a wide variety of FX (effects processors) to cover all your audio processing needs. The FX implementation is robust and includes the ability to insert unlimited FX slots in several stages of the signal flow.

- Click the “FX” tab to open the FX page on the Single view.

- In Multi view the FX section is always displayed.


FX can be inserted on presets and some presets are even pre-configured with their own FX. To view the FX that are inserted on a loaded preset, click the

“Preset” tab of the FX tab.


The “Part” is like the channel on a mixing console. FX inserted in the “Part” tab applied to what ever preset is loaded into that part. Part FX appear after Preset

FX in the FX signal flow chain.

Aux 1 & 2

“Aux” FX work exactly like aux sends in a normal mixing console. The UVI

Workstation provides two Aux FX to work with (AUX1 and AUX2). Once an FX is inserted in AUX1 or 2, it can be applied to any preset or part that’s loaded into your UVI Workstation session.

When you select an “Aux” tab, a “Return” slider will appear to the right of the

FX screen. By default, the return slider is set to “0.00 db” (unity gain). Use an

Aux’s return slider to set the overall amount of Aux FX that is heard in your

UVI Workstation session.

- To bypass an individual FX:

Click the FX’s “Bypass” button to temporarily disable (bypass) the effect.

- To bypass an entire FX tab:

There is a global bypass for each FX tab (Preset, Part, Aux1 & 2, Master). Click the vertical bar next to the FX tab name to bypass all effects inserted in an FX tab.

- To delete/remove an FX slot:

Press the “X” button (located to the right of the effect’s “Bypass” button). Be careful since this action cannot be undone!

- To replace an FX:

Right-click or Control-click the name of the effect. This action opens the FX

Browser, enabling you to choose a different effect.

- “Arrows” that appear to the right of an FX slot are only active if there are more than five parameter controls available for an effect. Active “Arrows” will be shaded darker. Use the “Arrows” to show or hide these additional controls.


“Master” FX appears at the end of the overall signal flow chain of the UVI

Workstation...that means any inserted Master FX will be applied globally to your entire UVI Workstation session.

Working with FX

To add an FX slot:

1. Select an FX tab. If you want to use a Preset or Part FX, be sure

to also make a part selection (in the “Part” section).

2. Click “add FX”. The FX Browser is displayed.

3. Select the type of effect (FX algorithm) you want to insert.

The algorithm’s FX presets are displayed.

4. Click on a preset name to preview the effect in real-time.

5. Double-click or press “OK” to insert the effect.

- The “Sync” option will appear for tempo-based effects like delays, autopan, and tremolo. When “Sync” is enabled (highlighted), the effect’s tempo related features will be locked to the host or UVI Workstation tempo.

Here is the list of the current FX algorithms included with the UVI Workstation.

Each FX category contain their own presets... hundreds of FX presets in total.

About IR Verb

UVI Workstation is equipped with convolution (or sampled reverb).

Convolution is a process where the characteristics of a real acoustic space are directly sampled, such as a church, concert hall, theater, or outdoor space. The resulting impulse response (IR) consists of an audio file that stores the actual sound decay characteristics of the acoustic space. By sophisticated signal processing, that impulse response can then be applied to any audio material, making it sound exactly as if the audio were being heard in the acoustic environment captured by the impulse response.

> Convolution reverb is the most realistic type of reverb ever developed because it faithfully reproduces the actual characteristics of real acoustic spaces. As a result, it requires intense computer processing. So for best performance, when you choose a convolution reverb preset, be mindful of the amount of processing demands it imposes on your computer.

Convolution Reverb settings

Here is a brief summary of the reverb settings for convolution reverbs.


PreDelay is the amount of time before you hear the very first reverb reflections.

For example, if you are in a large room, it takes longer for the first reflections to return and be heard. PreDelay is useful for clarifying the original sound. For example, if you apply a larger amount of predelay to an instrument, the reverb reflections won’t start until after a note has been played.

Reverb time

Reverb time controls the length of the reverb tail (the portion of the sound as it trails off to silence). Longer reverb times make your music sound like it is in a larger space; shorter times sound like a smaller space.

The maximum allowed reverb time varies and depends on the specific acoustic space you have chosen to use. Longer reverb times cause your computer to work harder. So you can conserve computer resources by choosing shorter reverb times.

HP damp

HP damp is a high shelf filter that reduces low frequencies of the reverb as you increase the HP damp setting. Positive values damp high frequencies, while negative values expand high frequencies.

LP damp

LP damp is a low shelf filter that reduces high frequencies of the reverb as you increase the LP damp setting. Positive values damp low frequencies, while negative values expand low frequencies.


Spread controls the stereo imaging of the reverb. If you turn this control down, the reverb effect will become mono.


A signal with no reverb applied to it is commonly referred to as being “dry”.

Therefore, a signal that is being processed with reverb is referred to as being

“wet”. The Wet setting does what its name implies: it controls the amount

(volume) of the treated (wet) signal.

> If you want more reverb, turn up the Wet setting; if you want less reverb, turn the Wet setting down. If you want to hear reverb on a part, make sure you turn up the part’s reverb slider.

Computer performance

Because of the intensive processing required to produce a convolution reverb in real time, a fast PC or Apple Mac is highly recommended when using the convolution reverbs. The processing demands of convolution reverb can be reduced by the following techniques:

- Shorter reverb times require less processing power. Choose shorter reverbs.You can also simply turn down the reverb.

- Raise the buffer size of your audio device (hardware).

- If your host audio application has track freeze or bounce-to-disk features, use them to “print” CPU-intensive UVI Workstation tracks.

Once the parts are rendered as audio, you can take them off line to free up resources.


UVI Workstation™ Manual



Name convention

Loop: a pre-sliced audio file (Rex, Apple Loops, UVI Loops ...)

Phrase: any other audio file (Wav, Aiff, SD II, mp3 ...)

In Single view, the Loop section provides settings for the loop or phrase loaded into the currently selected part. This tab won’t display if an instrument has been loaded to the selected part.




Click the Slice button to put the loop into Slice mode. If a “non-sliced” soundfile is loaded in the currently selected part, the Slice button becomes unavailable.

1. Modes (sample - stretch - slice)

When Auto-play is deactivated on the selected part, Slice mode can work in the same fashion as described above for Stretch mode: the MIDI note you play to trigger the loop or phrase affects the part’s pitch, but not the tempo of the part. Slice mode also lets you play chords.

Slice mode differs from Stretch mode in that it can play the sound without any MIDI triggering. It’s like having a very basic loop sequence for each part. To see how a part responds to tempo sync, review the “Loop sync” section of the manual.

Slice > Map

Sample, Stretch, and Slice modes provide different playback behaviors.

SAMPLE: plays the soundfile (loop) like a regular sampler

STRETCH: the length of a sample is not pitch-dependant.

SLICE: the default mode for loops

Note: A native “sliced” soundfile can be switched to Stretch or Sample mode, but a “non-sliced” soundfile can’t be switched to Slice mode.


In Sample mode, the loop or phrase is triggered like a traditional sampler: as you play the sample with different keys up and down your MIDI controller, both the pitch and the duration of the sample will change. The higher the note, the higher the pitch of the sample and the faster it plays. The lower the note, the lower and slower the sample plays.

In Slice mode you can enable the Map button. The Map button splits up the loop into different slices, mapped chromatically to MIDI notes starting at C3. This allows you to play each individual slice by itself from a note on your MIDI controller.

By playing the notes upwards chromatically, you can recreate the original loop. But you can mix up the notes up to play the slices in any order you want. Slices open up a world of possibilities for restructuring the beats of a loop, quantizing or groove quantizing loop slices, etc.

Map mode also allows you to drag and drop the MIDI version of the loop, into a

MIDI track in your host software. You can then manipulate the loop as MIDI data in your host.


> Summary of modes

Loop mode Works with MIDI note affects Tempo set

In Stretch mode, the MIDI note you play to trigger the loop or phrase affects the sample’s pitch, but not the tempo. For example, if you play a three-note chord, all three triggered loops (or phrases) will play at the same speed (but at the different pitches you played). Playback speed is determined by the speed controls.

> UVI Workstation uses one of the best real-time time-stretch in the market.

2. Controls


Speed control

The Speed Control slider lets you speed up or slow down the selected sound.

This setting is applied relative to the other sync and tempo settings. The speed range is from 50% slower to 50% faster than the original, which is represented by the center position of the slider. Double-click the slider to return to zero.


Half and Double buttons let you slow down the loop or phrase to one half or one quarter of the loop’s current tempo, or speed the loop to twice or four times the current tempo.

Similar to the Speed Control slider, the Half/Double setting is applied relative to the other sync and tempo settings. It can be combined with the Speed Control slider, allowing you to specify any tempo within a range of 25% to 400% of the current tempo. The current tempo of UVI Workstation can be set from 1 BPM to 300 BPM. These tempo settings give you an extremely wide range of tempo control.

Note: Half/Double speed controls do not work when in Sample mode!

Sample Start / Slice Start

The Sample Start slider lets you specify any point in a loop or phrase as the starting time for the Sample Start setting.

In Sample mode or Stretch mode > the Sample Start slider provides a range from zero 0 to 100%, where zero is the very beginning of the loop or phrase.

In Slice mode without mapping > the Sample Start slider provides a range from the first slice (0) to the last slice in the loop. The number of the last slice depends on the actual length of the loop and the number of slices in the loop.

> Example: if a two-bar loop is divided into 16th note slices, the loop will have a total of 36 slices. This also means that slice 18 is the downbeat of measure

2. So if you set the Sample Start slider to 18, the loop will start at the downbeat of measure 2.


When the Latch button is off (disabled), a loop or phrase plays for as long as you hold down its corresponding note on your MIDI keyboard (or any other controller).

When Latch is on (enabled), a loop or phrase continues to play, even if you lift your finger from the key on your controller. If the loop or phrase is in Stretch mode, or if it is a loop in Slice mode (without mapping), it will continue to repeat indefinitely. If the loop or phrase is in Sample mode, it will play once and then stop. In either case, play the same key again to make the loop or phrase stop playing.

The menu under the Latch button lets you specify when the loop or phrase begins to play after you trigger it.

In Stretch mode, loops and phrases always begin playing at the beginning of the loop or phrase (plus any offset added by the Sample Start slider). So if you choose “Next Beat”, the loop or phrase will begin playing at the next beat.

The Position sync setting keeps the loop’s beats aligned with the global tempo, regardless of when the loop starts to play (either on the next beat or next bar).

> Position sync is only available for loops, not phrases.

3. Sync

Note: In this section, the Key display shows the root key for the loop or phrase. The

Key display is for informational purposes and it cannot be changed.

The Sync settings in the Loop Sync menu let you synchronize the loop or phrase to UVI Workstation’s global tempo setting. If the Sync to Host option is enabled, the loop or phrase will also synchronize to the tempo of your host software.

Synchronization mode




The loop or phrase does not sync to tempo.

The loop or phrase follows tempo, but not position.

Loops and phrases always start at the beginning.

Not available for phrases. Loops follow both tempo and position (their beats and barlines always align with the tempo).


UVI Workstation™ Manual



When you choose Tempo in the Loop Sync menu, the loop or phrase will play at the tempo indicated by UVI Workstation’s BPM setting (or your host software if the

Sync to Host option is enabled). In Tempo mode, the loop or phrase always starts at the beginning (or at the location determined by the Sample start setting).

In addition, the loop or phrase will play at the instant it is triggered, so it is up to you to trigger the sound “on the beat”.

> If you trigger the loop or phrase between beats, it will play in tempo, but offset from the beat (relative to where the loop was triggered).


The Position sync setting only affects loops, but only when they are in Slice mode

(without mapping). When a loop is in Slice mode with Position sync, it might be helpful to think of the loop as looping indefinitely, whether you are actually playing the loop or not.

When you play a note to “trigger” the loop, you are actually just “unmuting” it, and it begins to play at the position in the loop that currently matches the tempo and meter of your UVI Workstation session.

> For example, if the loop is two bars long, and you trigger it at the second measure of your music, then the loop plays starting at bar 2 of the loop.

Loop Sync summary

Putting a loop into Slice mode and choosing Position sync gives you the highest degree of tempo synchronization because the loop will not only play in tempo, but its beats and barlines will always match the beats and barlines prescribed by the tempo.

Here’s a summary of the different loop modes and sync settings:

Sync off Tempo sync Position sync

4. Drag & Drop

Dragging audio data

When the audio data (audio waveform) icon is showing, this means that you are dragging a standard mono or stereo audio clip. You can drag and drop the audio loop (phrase) anywhere in your host software that accepts audio clips via drag & drop. For example, an audio track.

> A good rule of thumb is: if it works from your computer desktop, it should work from UVI Workstation.

Conforming audio to the host tempo

If the Sync to Host option is enabled, when you drag and drop a loop or phrase to an audio track in your host application, the loop or phrase will snap to the host’s tempo and will conform to the host’s timeline.

> If your host software has the ability to “snap” the drag and drop operation to measures and/or beats in your session, you can produce rhythmically accurate results quickly.

> If Sync to Host is disabled, the loop or phrase retains its original tempo when placed in the track.

Dragging MIDI data

When you see the MIDI data icon (shown above), this means that you are dragging a sliced, mapped loop in the form of MIDI data. Therefore, you should find a destination in your host software that accepts MIDI data, such as a MIDI track.

> Your host application may also provide other possible destinations for mapped loops. For example, a MIDI loop can be dragged into a clipping window in DP.

Triggering UVI Workstation slices from the host

When a mapped MIDI loop is dropped into a MIDI track, it looks similar to the

MIDI data shown above (in the example graphic). Each MIDI pitch triggers a different loop slice. If you play notes chromatically upwards from C3, you will recreate the original loop. If you play the notes rhythmically in a different order, you’ll play the individual loop slices but the result will sound quite different from

(but similar to) the original loop.

> In order to hear the dragged MIDI loop, be sure that the MIDI output of the host software MIDI track (the MIDI track where you dragged the mapped loop) is routed to the UVI Workstation part that contains the mapped loop.



The UVI Workstation Expert Mode is a powerful and very useful mode for live playing and studio productions. In the Multi view, click the Expert Mode button to display the Expert settings. The Expert controls can be divided into three main parts: Performance, Streaming, and Output settings.



1. Performance : Split, Velocity & Key Switch

The Keyswitch settings allow you to load multiple presets into two or more parts and then dynamically play and mute them from your MIDI controller using key switching, note range, velocity range or any combination of the three parameters.

This powerful feature gives you a great deal of real-time control over the instruments you are playing from your MIDI controller.

Setting up parts for keyswitching

Load the instruments you would like to include for use. Then assign the instruments to the transmit MIDI channel you will use to control them (from your MIDI controller). The instruments should all share the same MIDI transmit channel.

The Keyswitch settings

Individual Keyswitch settings are available for each UVI Workstation part.

Configure the Key Range, Velocity Range, and/or Key Switch settings as desired for each part (instrument). You can use any combination of the three settings.

- To enable a Keyswitch setting: click the check box next to the setting, so that the check box appears filled in. An empty box means that the setting is disabled

(not used).

- To change a note-on velocity number or pitch with the mouse: drag up or down.

- To change the note-on velocity number or pitch from your MIDI controller: doubleclick the value to make it turn red, and then play your MIDI controller to enter the desired velocity value or note pitch.

Key Range

The Key Range determines the note range over which the instrument will play.

Velocity Range

The Velocity Range determines the MIDI note-on velocity range that will trigger the instrument.


Key Switch

The Key Switch determines the MIDI note that can be played to toggle the instru- ment on and off. Note that multiple instruments can have key switches, allowing you to turn them on and off independently or in groups (for instant stacks).

> A good way to learn about keyswitching is to just see it in action. Keyswitching is used in some of the multis provided with UVI Workstation, so you can load them up and play them to see how keyswitching works.

2. Streaming

Disk streaming allows you to load very large presets (that consist of a large amount of audio sample data) into the UVI Workstation, even if the samples are larger than the amount of free memory (RAM) available in your computer. Rather than loading an entire sample set into RAM, UVI Workstation reads (streams) the samples from the hard drive as the preset is being played. This allows UVI Workstation to play combinations of presets that add up to a gigabyte of sample data or more.

By default, every part is set to streaming mode.

Enabling streaming

Disk streaming can be enabled for each part in UVI Workstation. For example, you could turn on streaming for Parts 1-16, but leave it turned off for parts 17-

32. Streaming can be enabled on as many parts as you like.

To enable streaming for a part in the Expert mode Streaming settings: click the part’s Streaming check box (located to the left of the Output column). The check box will appear filled, when disk streaming is enabled.

3. Output

The Output setting let you assign each part to one of 17 possible stereo output pairs (the main outs + 16 stereo aux outputs). Each output pair can be assigned to a pair of physical outputs on your connected audio hardware. This provides a great deal of flexibility in sub-mixing with UVI Workstation.

> The list of stereo pairs that you see in each Output menu depends on the situation in which you are running UVI Workstation. (When working in Digital

Performer for example, UVI Workstation will list the MAS outputs).

Multiple outputs and Stand-alone operation

If you are running UVI Workstation as a stand-alone application, the Output menu displays a Main Out pair, plus 16 additional separate output pairs (num- bered 2-17).

Multiple outputs and plug-in operation

If you are running UVI Workstation as a plug-in, the Output menu displays the outputs that are made available to the plug-in by your host software.

> For example, in MOTU Digital Performer, you will see pairs of busses, as supplied by Digital Performer’s current studio configuration. Use your host software to map the virtual busses to the physical outputs on your audio hardware.


UVI Workstation™ Manual


To instert an arpeggiator in a part, you need to display the Single view in the UVI Workstation, then click on the note icon

Using the Arpeggiator

The Arpeggiator can be employed as a pattern gate, arpeggiator, or even an advanced rhythmic processor for your live MIDI performance or sequenced MIDI tracks. Arpeggiotor can be insterted in an unlimited number of parts.


The number of steps is set with the NumSteps knob, from 1 to 128. The Resolution menu sets the value of the steps, in metric values from 32 bars to 64th note triplets.

You can manipulate each step in the following ways.

Enable/disable step >

Click checkbox

Merge with previous step > Shift-click checkbox

Change velocity >

Change length >

Drag slider/up down

Shift-drag slider left/right

Additionally, the step length can be set globally with the Step Length knob. The

Step Length knob setting is combined with the setting of each individual step. For example, if you have shortened a step to 50% by Shift-dragging it and have the

Step Length knob set to 50%, that step will be 25% of the usual length.

The Arp Vel. Blend knob controls the depth of the steps’ velocity. At 0%, the full velocity range is used; at 100%, a constant velocity is used (effectively making all steps the same velocity, regardless of their individual values).

Trigger Mode

Trigger Mode determines where in the pattern of steps each note will start.

Note: Each played note restarts from the first step.

Legato: the first played note starts on the first step, and the pattern of steps continues as additional notes are played. If all held notes are released, the pattern will restart from the first step when the next note is played.

Song Position: the position in the pattern is determined by the song position, regardless of how notes are being played.

Hold >

when enabled, arpeggiated notes are held.

Mode >

to determines the order in which the arpeggiated notes are played.

Octave >

number of octaves above/below the notes will be arpeggiated.

Strike and Repeat

To further tailor the way in which each arpeggiated note is triggered, use the following settings:

NumStrike: number of times the note is triggered before moving on to the next

RepeatBottom: the bottom note is repeated

RepeatTop: the top note is repeated

Groove Amnt: applies swing to the steps

Arpeggiator presets management

Loading presets > the apreggiator provides three sub-menus of well programmed presets : Arp, Chord, and Mono. You can also use the arrow to browse between all the presets.

Saving your own presets > press save and give a name to your own preset. It will be added in the User part on the loading preset browser, and you will be able to load it at any time in any part you want.



UVI Workstation is just the begining of your UVI experience...

Now you’re familiar with the UVI Workstation - hoping you did read the full manual until this page ;-) -, you now have access to all the excellent sounding UVI libraries and instruments.

UVI Workstation™ Manual


> How do I make UVI Workstation work in my sequencer?

UVI Workstation is an audio instrument plug-in. You will call UVI Workstation up in your sequencer on an audio track, aux track, or instrument track, depending on how your sequencer handles virtual instruments.

To get MIDI into UVI Workstation, you need a MIDI track (or instrument track).

The MIDI or instrument track must be record-enabled in order to receive MIDI from an external source into UVI Workstation.

> I have my preset loaded, but I don’t hear anything.

If you are playing notes from an external controller, make sure the MIDI track or instrument track in your host software is record-enabled. For other MIDI troubleshooting tips, see chapter 9.2 “MIDI trouble- shooting”.

> UVI Workstation’s MIDI activity LEDs are flashing, so it’s receiving MIDI data successfully, but I still don’t hear any sound.

It’s time to check audio. See chapter “Audio troubleshooting”.

> When I play on my keyboard, there’s a delay before I hear a note.

In order to get the fastest possible response, you’ll need to set the sample buffer of your audio hardware driver to a low number. Experiment with this setting to get the best response and computer performance.

> How do I get UVI Workstation to send each part to a different audio output?

Not all sequencers support this feature. If your sequencer does support this feature, you’ll see several choices in the audio output menu for each part. The additional choices (other than Main) let you assign the part’s output to a bus, which can then be routed anywhere in the virtual mixing environment.

> Why is the output of UVI Workstation distorted?

It is possible for UVI Workstation to output more than unity gain. This can happen if you layer presets or in some cases, if you use resonant filters that add gain. Keep an eye on the output level of the UVI Workstation track and attenuate that signal if it gets too hot.

> How do I record the audio output of UVI Workstation?

Most sequencers have a freeze function that renders the output of the UVI

Workstation as an audio file. If your sequencer doesn’t have this feature, bus the output of the the UVI Workstation track to another audio track, and record the audio output of UVI Workstation onto that track.

> Everything is working fine, except that intermittently, samples don’t play for no apparent reason. Why?

Check your polyphony setting for the part. If you’re sure the part has more than enough voices, are you running Mac OS X? If so, how many samples have you loaded into the UVI Workstation? As a general rule of thumb, you shouldn’t load more than about 70% of the total amount of RAM your computer has (±10%).

For example, if your computer is equipped with 1 GB, don’t load more than around 700 MB of samples into the UVI Workstation.

Because of Mac OS X’s built-in memory management features, there is potentially an unlimited amount of “virtual RAM”, but when Mac OS X runs out of real

RAM, it starts caching the overflow to disk. This can wreak havoc on the UVI

Workstation performance. Unfortunately, Mac OS X doesn’t provide any means for applications to know — or report to the user — that it has run out of real

RAM, so there is no way for UVI Workstation to alert you if Mac OS X is caching the UVI Workstation samples to disk. Therefore, if you are loading lots of sample data, you need to keep an eye on how much RAM they use up. There are third-party utilities available that can help you keep tabs on your RAM usage.

This is also true in Windows OS.

> Can I use UVI Workstation and the UVI Tutorial Set sound library on film trailers, multimedia, or game projects?

Absolutely. No specific license is needed.

> Do I need an iLok key to run the UVI Workstation ?

No you don’t. But you will absolutely need an iLok key if you want to load copy protected libraries like the ones you can buy at

> UVI Workstation is really great as a free player, but what should I get to have more editing feature ?

The answer is simple : the incredible MachFive 3 Universal Sampler from

MOTU. This is the big brother of UVI Worktation. So everything you can do in

Troubleshooting is always simplest and most effective when the exact problem can be specified clearly and concisely. If you are surprised by an error message or by seemingly erratic behavior in the program, take a moment to jot down the relevant details: exactly what the error message said (including any error ID numbers), what actions were done on-screen just before the problem occurred, what kind of file you were working with, how you recovered from the problem, and any unusual conditions applying during the occurrence of the problem. This may not enable you to solve the problem at once, but will greatly aid in isolating the problem should it reoccur.

If the problem you are encountering seems inconsistent, try to determine what the necessary pattern of actions are that will cause it to occur. Genuine bugs in application software like UVI Workstation are almost always consistent in their manifestation: the same set of actions under the same conditions invariably brings about the same results. Determining the exact cause of a bug often requires experiments which replicate the problem situation with one factor changed: choosing a different (smaller) preset, opening UVI Workstation in a different host application... If the problem is truly inconsistent, then it is likely to be a hardware problem: a bad hard drive, a failing computer motherboard...

Isolate the problem...

One of the best troubleshooting techniques is to try to isolate the problem. If you can whittle down a complicated setup or scenario to a much simpler case, chances are you’ll zero in on the problem more quickly. For example, you could try running UVI Workstation in a different host application to see if the problem persists. If it does, it may have to do with the actual samples, presets, and/or performances being used.

Simplify your setup...

One of the most common causes of problems is a conflict with other software in the system. Run UVI Workstation by itself, with no other plug-ins or virtual instruments, and see if the problem you are having still occurs.

If you cannot open a particular UVI Workstation project or session in your host application...

First try opening other existing files, or a new file, to be sure the UVI

Workstation is working at all. If other files work fine, try temporarily removing the UVI Workstation plug-in, or disable audio in your host application. If other files also exhibit similar behavior, then you know that the problem is not specific to one file.


The most important tool for tracking down MIDI input problems is the MIDI

Activity LEDs for each part. If there is a hardware problem, or if your channel assignments are wrong, the problem should be apparent by looking at the MIDI

LEDs. In order for external MIDI to get to UVI Workstation, the MIDI track or instrument track must be record-enabled. A quick test to determine whether

MIDI is reaching the track is to hit record and tap a few notes on your controller.

If no MIDI appears in the track, check that your controller and MIDI interface are set up properly. If MIDI data does show up in the track, and your sequencer uses a separate MIDI and audio track for virtual instruments, make sure the

MIDI track output is assigned to UVI Workstation and is assigned to a part that has a preset sound ready to go.

If UVI Workstation is unable to play any MIDI data...

Does your host software receive MIDI data from your MIDI controller? Does

MIDI play back successfully to other MIDI instruments? If the answer is no to either question, double-check your cable connections and MIDI controller settings. See if your controller registers in the MIDI system management software on your computer, if any (ex. Audio MIDI Setup on the Mac). If you are trying to play the UVI Workstation from your MIDI controller, make sure that the UVI

Workstation MIDI track or instrument track in your host software is record-enabled. Often times, only A/B tests will reveal the source of the problem. It may be necessary to switch your MIDI cables, and if possible, to try using a different

MIDI interface or synthesizer for input/output. The easiest way to test if MIDI data is actually getting to the UVI Workstation is to look at the MIDI activity

LEDs in the Part list.


In order for audio to be heard from UVI Workstation, the output of the audio, aux, or instrument track in your host software must be sent to an output that is connected to speakers or headphones. Can you play back any pre-recorded audio? That’s always a good way to check that the rest of the audio system is set up correctly. In some cases, a sequencer requires an available voice for the

UVI Workstation playback.

• Make sure all outputs and voice assignments are correct in the track.

> If you still don’t hear sound, check the following things:

•Make sure the volume is turned up on the part you are playing, as well as the

UVI Workstation’s global volume setting.

• Make sure that the appropriate faders are up in your host.

• Make sure you have cables connected to the correct plugs on the outputs of your audio hardware.


Keep up-to-date backups of your UVI Workstation sounds folder, so that you always have copies of the most recent work you have done. Almost any software problem is survivable as long as you have kept backups of your work.

Keep plenty of free space on your hard drives to prevent the computer from running out of disk space.
