Setup.exe. The setup program will suggest C:\Program Files\Native Instru-

ments\Pro-53 Xpress as the path for the destination folder. Youmay also choose another folder if you wish.

Installed Folders, Files, and Links

The setup program creates a new folder called Pro-53 Xpress\ inthe installation directory (Program Files\Native Instruments). Thisfolder contains the files required to operate the software.

If you do not choose a different program group during the instal-lation, links to PRO-53 XPRESS and a ReadMe file are added tothe Start menu under Programs Native Instruments.

VST Plug-in Installation

Start the installation by double-clicking Pro-53 XpressSetup.exe.

When the choice is given by the installer, select VST Plug-infrom the list of components to install.

You can now choose to automatically search for the VST plug-in folder or manually select the VST plug-in folder of yourchoice. Please select the option that best suits your installa-tion requirements.


Note: If more than one host program for VST 2.0 plug-ins is in-stalled on your computer, simply copy the Pro-53 Xpress.dll fileinto the VST plug-ins folders of these programs. Windows: If theVST plug-in files are not visible in the Windows Explorer, selectthe Show All Files option. This option is located in the Explorermenu View Folder Options... on the View tab below HiddenFiles. Optionally, you can set up your programs so that they all usethe same VST plug-ins folder.

HPRO-53 XPRESS as StandaloneThe stand-alone version of PRO-53 XPRESS allows you to use theapplication independently from other programs. In order to usethe Standalone version you have to do the audio and MIDI set-tings first. You can call up the Audio + MIDI Settings setup dialogfrom the File menu of PRO-53 XPRESS. For setting the standal-one interfaces please choose Setup... from the File menu.

Soundcard (Audio Interface)

Audio + MIDI Settings dialog

Interface: Choose the fastest interface protocol supported by yourinterface, which will be ASIO or Core Audio. For Windows, you canalso use DirectSound and Multimedia (also called MME), but ex-pect a significant delay between the time you play a note and thetime you hear it.

Sample rate: The drop-down menu will display compatible samplerates for your audio interface. 44.1kHz is the same sample rateused for CDs, and is the most universal choice. However, someaudio interfaces offer 48kHz and 96kHz (PRO-53 XPRESS ac-cepts up to 96kHz sample rates). These higher rates stress yourcomputer more, but offer somewhat better high frequency re-


sponse. If you are using PRO-53 XPRESS standalone, choosewhichever rate you prefer. When used as a plug-in with a host pro-gram (e.g., Cubase, Digital Performer, Logic, Sonar, etc.), the hostwill determine the sample rate.

Output Device: Use ASIO written specifically for your audio inter-face (not ASIO DirectX or ASIO Multimedia, unless no otherchoices are available), or for the Mac, Core Audio.

Input Device: Here you can define, which of the installed audiointerfaces is used as audio input. This setting depends on thedriver you have chosen under Interface.

Note: For some interfaces (e.g. ASIO or Core Audio) the Input De-vice setting is not available. You can select the inputs for the cho-sen driver on the Routing tab instead.

Output Latency: This field displays the output latency. For somedrivers you can adjust the latency individually using a fader.

Routing

If your sound card offers multiple outputs, you can choose whichones connect to PRO-53 XPRESS. Inputs will not be available toPRO-53 XPRESS. Click on Outputs to select the outputsavaila-ble to you. If you have a multichannel soundcard then you canuse any of the available outputs for PRO-53 XPRESS, just click


EN

GLIS

H

on the drop-down menu to see your choices. Note that the rightand left channels are independent and can be assigned to anyinputs/outputs not just stereo pairs as well as disconnectedfrom audio ins and outs.

MIDI

If your MIDI interface offers multiple ins and outs, you canchoose which one connects to PRO-53 XPRESS. When you clickon the MIDI tab youll see a list of MIDI I/O. Initially, each onewill be Off. This field is a toggle click on Off to turn an input oroutput On, click on On to turn an input or output Off.


PRO-53 Xpress operation

PRO-53 XPRESS contains 64 presets, which reproduce the origi-nal sound of its famous predecessor authentically.

Icon: Click on the PRO-53 XPRESS Icon in order to open theAbout window. The About window contains information aboutthe software version as well as links to the NI website (e.g. ad-ditional sounds and upgrade offers, support and forum).

Presets section

Please note: Some presets are monophonic. This means that youcan only play one note at a given time. This is a wanted behavior.When you play these sounds and you press the second key (whilethe first one is still pressed down) you just hear the note whichyou played last. When you now release the last key (while stillholding down the first one), you hear again the first note whichwas still active but muted while you pressed the second key. Youcan achieve a very expressive solo play with this behavior.

Bank: There is one preset bank included in the PRO-53XPRESS installation. This bank is called Factory Bank. Ad-ditional preset banks can be purchased online following theaccording links in the PRO-53 XPRESS About window whichcan be opened by clicking on the PRO-53 XPRESS icon.

Number: This field displays the number of the currently se-lected preset within the chosen bank. Since it is possible tocall up presets by standard MIDI program change messages,the number displayed in PRO-53 XPRESS corresponds to theMIDI program change numbers -1. Depending on which pro-gram number format your MIDI device has, the PRO-53XPRESS number will match exactly the number of your MIDIdevice when you call up a program change, or it will always beone digit higher when the MIDI device begins counting from 0.Left and right hand of the number field there are buttons fornavigation to the previous (left) and next (right) preset. Youcan also click on the number field and drag the mouse up ordown with the mouse button pressed in order to navigatethrough the preset bank. Dragging up increases the presetnumber, dragging down decreases it. In the standalone versionpresets can also be switched by using the left and right cursorkeys of your computer keyboard.

Preset Name: This dropdown menu serves for displaying thename of the currently selected preset and allows to choose apreset from the list. Click on the small triangle or anywhere inthe preset name field and keep the mouse button pressed untilyou see the preset list. Now move the mouse cursor to the de-sired preset and release the mouse button. If you want tochoose a preset which is not in the visible area of the list, clickwithin the preset name field, keep the mouse button pressed,move the mouse pointer to the right, so that you leave the pre-set list area and release the mouse button, so that the presetlist remains opened. Now you can use the scrollbar on theright side of the preset list to navigate to a different section ofthe list. When you see the desired entry click on it once, sothat the preset will be called up in the preset name field.


NI logo: Click on the NI logo in order to open the About win-dow. The About window contains information about the soft-ware version as well as links to the website (e.g. additionalsounds and upgrade offers, support and forum).

Parameter section

Please note: The first five paramter are always in center positionwhen calling up a preset. This is normal and reflect the behaviourof the PRO-53 Easy Edit page. Any adjustments you make withthese knobs, modify the selcted preset in a relative way. Example:You call up a sharp bass sound with short Attack. When you nowmove the Attack knob to the left, the Attack becomes evenshorter, when you move it to the right, the Attack becomes longer.

Brightness: controls the amount of brightness for the filter.This parameter is often called Cutoff in analog synthesizers.

Resonance: sets the resonance (boost at the cutoff frequency)for each filter. A very high setting will cause the filter to oscil-late which can cause an audible whistling.

Shape: determines the amount of effect the parameters Attackand Decay have on the sound. The higher you adjust Shape,the more you hear the sound modification.

Note: In order to hear any effect of the parameters Attack and De-cay, the parameter Shape has to be set at least slightly higherthan 0. For some presets you have to set Shape to a relatively highvalue in order to hear any modification.

Attack: increases the attack time (the duration between thestart of a sound and its first peak)

Decay: increases the decay time (the duration between thepeak of a sound and its sustain phase)

Effect: increases the effect level. The type of effect you get de-pends on the selected preset and can not be modified in PRO-53 XPRESS.

Pan: stereo placement control for the Instrument. This controldetermines the Instruments location in the stereo field.

Volume: The Instruments level control.

Keyboard section

MIDI lamp: The lamp indicates incoming MIDI events likeMIDI notes and MIDI controller data.

Modulation wheel: You can either use the virtual or a real mod-ulation wheel (sending on CC1) to control the sound parame-ter(s) the sound designer has assigned to this controller. Youcan not modify the modulation target in PRO-53 XPRESS.

Virtual Keyboard: When PRO-53 XPRESS is receiving MIDInotes, you can see the virtual keys moving down. You can alsotrigger notes by clicking with the mouse on a key.

MIDI ControllersPRO-53 XPRESS uses fixed MIDI CCs (Continuous Controller) forcontrolling the interface parameters. Usually you need to have aprogrammable MIDI controller unit in order to produce theseMIDI controllers. Additionally to the visible interface parametersyou can also use Expression and Hold pedals for most expres-sive playing. Here is a list of the supported MIDI controllers:

Brightness (CC74) Resonance (CC71) Shape (CC70) Attack (CC73) Decay (CC75)


Effect (CC12) Pan (CC10) Volume (CC7) Modulation (CC1) Hold pedal (CC64): You can use a Hold pedal sending on MIDI

controller 64. A hold pedal serves for sustaining all playednotes even if you have released the keys until you release thepedal again.

HAppendix A: More About LatencyA computer adds a certain amount of delay (latency) when pro-cessing audio signals. Fortunately, with todays computers andlow-latency sound card drivers, this delay can be so small that youcant hear it (e.g., under 3 milliseconds, which is about the samedelay caused by moving your head one meter further away from aspeaker).

Optimizing System ResponseAny computer-based audio system has some delay between theMIDI input and audio output. Even the most powerful computercan only do a certain number of calculations per second; signalprocessing demands a lot from a processor, so its important tominimize any computer-based delays.

Fortunately, three main factors make delays virtually insignificant,assuming you have a suitable computer setup (see SystemRequirements).

Todays multi-GigaHertz computers are so fast they dramati-cally reduce latency.

Many sound cards and audio interfaces include drivers opti-mized for low latency.

PRO-53 XPRESS, despite its superb sound quality, is writtenvery efficiently.

Use Low-Latency DriversDrivers are pieces of code that handle communications betweenyour computer and audio interface, whether built into a computeror attached via USB or FireWire. The more efficiently they transferdata between audio interface and computer, the lower the latency.

PRO-53 XPRESS works with two low-latency driver types:

ASIO (Advanced Streaming Input Output). This cross-platformprotocol was originally developed by Steinberg.

Core Audio (Mac only). This low-latency protocol was createdby Apple for the Macintosh, starting with OS X.


If your audio interface does not support one of these protocols,you will likely hear an audible delay if you play through PRO-53XPRESS. Although PRO-53 XPRESS can work with the Direct-Sound and MME drivers used with Windows machines, it will notmake for a satisfying playing experience.

How Low Can You Go?1.5 ms of latency approaches the theoretical minimum, becauseit will always take some time to convert digital to analog. However,note that ultra-low latency settings (or higher sampling rates)make your computer work harder, which may limit the number ofinstances of PRO-53 XPRESS you can add to your host program,while still obtain audio thats free of clicks, pops, or dropouts. So,here are some tips on living with latency.

About Samples and BuffersAudio cannot be handled continuously by a computer, but has towait its turn while other operations are being carried out. As aresult, sound cards create a buffer, which can hold a certainnumber of samples, where data can be stored and released asneeded to create a smooth flow of data. If theres an interruptionin the data flow for a little bit, no problem: Theres some reservein the buffer. An analogy would be if you had a hose that didntdeliver water continuously, but in bursts. So, you use a bucket tostore the water from the hose, and release the water from thebucket as a smooth, continuous flow.

If the bucket (buffer) is large, then you can store more water incase the hose goes dry for a bit. But it will take longer to fill thebucket, which is equivalent to latency. A smaller bucket takes lesstime to fill, but the hose had better deliver water on a prettycontinuous basis.

All ASIO audio interfaces and sound cards include a control panelwhere you can adjust latency. This may be given as the number ofsamples per buffer, as shown in the Terratec EWX control panel:

The Terratec EWX ASIO control panel lets you choose a particu-lar number of samples/buffer. The display then shows the result-ing latency. In this case, 256 samples/buffer has been selected,giving latency of just under 6 ms at 44.1kHz. Setting this to 128samples/buffer will reduce the latency, but may stress out yourcomputer more.

Some control panels simply show the latency that results fromchoosing a particular setting in milliseconds rather than showingsamples/buffer.


Creamwares ASIO control panel simply lets you choose the de-sired latency; buffers are adjusted behind the scenes withinthe Creamware Scope application (in this case, to 128 sam-ples). The Device Setup panel in Cubase confirms the latency,which is about 4 ms, but doesnt indicate the buffer size.

Warning: Different Types of ASIOIts extremely important to use the ASIO driver written for the cardyoure using. There are also generic ASIO drivers, typicallycalled (for Windows) ASIO DirectX Full Duplex Driver or ASIOMultimedia Driver. There will usually be a drop-down menu in thehost program to choose the desired ASIO driver. Youll know youvechosen the right one when theres a dramatic decrease in latency.

With the generic ASIO Multimedia Driver selected, the output la-tency is a totally unacceptable 749 ms almost one second! Bychoosing ASIO Scope (the driver written for the sound card usedin this example), the latency shrinks to 4 ms.

Tips on Minimizing Latency Set latency to the highest comfortable value. 256 samples/

buffer is very responsive yet gives your computer somebreathing room. 512 samples may also be acceptable, any-thing more will create too much delay. If you cant get reliableaudio with 512 samples, its time for a better computer!

If your ASIO Control Panel shows latency in milliseconds,youll find that anything over 10 ms or so gives an audible de-lay. 5 ms is a good compromise between speed and minimumstress to your computer.

Download your sound cards latest drivers from the manufac-turers web site. This can make a huge difference in perfor-mance.

If you are recording in a host application and using softwaresynthesizers, use your programs freeze function (if avail-able) to disconnect some synths from the CPU. Or, render asoft synths output as a hard disk audio track (then remove thesoft synth), as audio tracks are less taxing on the computer.Hint: If you retain the MIDI track driving the soft synth, whichplaces virtually no stress on your CPU, you can always edit thepart later by re-inserting the soft synth.

Sometimes there are two latency adjustments: A Control Panelfor the sound card sets a minimum amount of latency, and thehost can increase from this value if needed. Or, the host maylock to the control panel setting.


Appendix B: About MIDIThe complete MIDI spec is fairly deep and complex. Fortunatelyfor MIDIphobes, there are only a few parts of the spec necessaryfor a basic understanding, so theres not really that much to learn.Lets start with MIDI basics.

MIDI BasicsA MIDI system requires something that sends MIDI messages(such as a footpedal or footswitch that says make the instrumentlouder, select this effect, add more echo, etc.) andsomething that receives these messages and acts on them, likePRO-53 XPRESS. Of course, this assumes your computer has aMIDI input so that PRO-53 XPRESS can receive MIDI messages.

Stripped to its basics, you can think of MIDI as a catch-all namefor the process of sending control messages from one device (e.g.,a footswitch) to another device (e.g., PRO-53 XPRESS) over aMIDI cable. Host sequencers also use MIDI data to record MIDInotes and provide automation for PRO-53 XPRESS when itsserving as a plug-in.

There are many different kinds of MIDI messages, most of whichrelate to keyboards, sequencers, drum machines, lightingcontrollers, tape recorders, and other gear we can ignore. WithPRO-53 XPRESS, 99% of the time you need to know about onlythree kinds of MIDI messages: MIDI notes, program changes(which call up different Presets) and continuous controllermessages (which alter PRO-53 XPRESS parameters in real time).

MIDI ConnectionsYour computers sound card probably has a MIDI in jack (receivesMIDI message) and MIDI out jack that transmits MIDI messages.There may also be a MIDI thru jack, which provides a duplicate ofthe signal at the MIDI in jack.

About Program Changes and Bank SelectTo understand program changes, take a trip with me down memorylane to the mid-70s, when disco ruled, synthesizers were not yetprogrammable, and guitar effects were starting to progress beyondfunny little boxes that ate batteries and burped noise. Guitaristsdiscovered early on that the hippest control on any signalprocessor was the in/out footswitch because it allowed you to bringan effect in as needed (distortion is wonderful, but not all thetime). Nowadays many MIDI keyboards have controls for calling upprograms (program change) and transmit the according programnumber via the MIDI out port. These numbers are recognized byPRO-53 XPRESS without any additional setting, so that thepresets there are switched according to the received programchange number.

About Continuous ControllersChanging from one program to another is a good start, butsometimes youd like to vary a particular parameter within anindividual program.

When you call up a programs parameter, you usually change itsvalue by turning a knob. The idea of continuous controllers cameabout because synthesizers and effects have pedals, knobs, levers,and other physical controllers that alter some aspect of thesound over a continuous range of values (this is why theyre calledcontinuous controllers, as opposed to a controller such as an on-off switch, which only selects between two possible values).

Unlike a program change, which is a single event, continuouscontrollers generate a series of events, such as a volume fade-in(each event raises the volume a bit more than the previous event),or change in some other parameter.

Like program changes, continuous controller messages aretransmitted over a MIDI output and received by a MIDI input. Thetransmitter usually digitizes the physical controller motion into128 discrete values (0-127). For example, pulling the controllerspedal all the way back generates a value of 0. Pushing down on


the pedal increases the value until at midpoint, the pedalgenerates a value of 64. Continuing to push on the pedal until itsall the way down generates a value of 127.

Note that continuous controller transmitters only send messagesreflecting a change; for example, leaving a pedal in one positiondoesnt transmit any messages until you change the pedalsphysical position.

HAppendix C: Trouble shooting and FAQQ: I do not hear any sound when clicking on the virtual keyboardwith the mouse. What can I do about it?

A: Please refer to the installation chapter of this manual andmake sure that you followed all instructions regarding the soundcard or host/sequencer setup, before contacting NI support. Alsomake sure that the Volume knob in PRO-53 XPRESS is not set tozero.

Q: When I play notes on my MIDI device, the keys on the virtualMIDI keyboard do not move. What is the problem?

A: This can either be a problem of the sound card configuration(since if PRO-53 XPRESS does not produce any sound, it will notreceive any MIDI as well) or the MIDI configuration. If you are us-ing a host/sequencer, make sure first, that the host/sequencer isreceiving MIDI from your MIDI device and that it can produce anyaudio signal. Please refer to the installation chapter of this man-ual and make sure that you followed all instructions, before con-tacting NI support.

Q: My Hold pedal works the opposite way as supposed to: When Ipress the pedal, the notes are not sustained, when I release it,they are sustained.

A: The format of the MIDI controller sent by the Hold pedal de-pends on the manufacturer. When you use the pedal together witha MIDI device from the same manufacturer, normally you shouldnot get any strange behavior. In many MIDI keyboards you canchange the behavior of the Hold pedal in the MIDI setup, so thatyou should be able to solve this problem there.
