Sampled Acoustics.

Hauptwerk Advanced Edition includes a  highly powerful convolution reverb engine. This allows high-quality real-time reverb to be added easily and natively, with no additional hardware or software needed. Using sampled acoustics from historic cathedrals and churches you can now customize the acoustics to match your environment.

Several IRs Included.

Impulse responses (IRs) are a recording of an acoustical space’s frequency spectrum. Creating the IR file allows Hauptwerk to load and replicate the properties of that same space by applying reverb to the audio output. Many IRs are included along with Hauptwerk Advanced allowing you multiple options to place your virtual pipe organ in many types of spaces. Many third-party IRs are also available from various Hauptwerk developers and can be purchased to be added to your IR collection.

Intelligent Combination System™

Register. Capture. Perform.

Powerful. Yet Flexible.

Hauptwerk provides a powerful, yet flexible, fully programmable Intelligent Combination System™ (ICS) that works for all virtual instruments. Included is a 999-frame fully random-access stepper, 100 master generals, 60 master scoped combinations, 60 reversible combinations, a 4-bank 31-stage master crescendo, a basic set of common master couplers that can complement the couplers a virtual organ has natively, and standard General Cancel and Set pistons. Virtual instruments often include native and independent combination systems of their own too and can be used along with Hauptwerk’s master combination system.


Effortless Control.

Effortlessly control your combination changes by connecting your MIDI hardware to the Hauptwerk combination system via the easy to use MIDI Learn system. You can also access all of Hauptwerk’s key combination settings through the control panels and activate them by hand using standard computer touch screens.

Hauptwerk is Worlds Beyond Digital.

Surround yourself with beautiful and natural church organs in their original acoustics critically sampled from each pipe. Hauptwerk offers an experience that you won’t hear with conventional digital organs. Subtleties of the organ’s blower, stop-action, keyboards, pistons and expression pedal sounds provide absolute realism.

Control Panels

Settings are just a touch away.

Mixer, Routing, Voicing

Hauptwerk’s audio routing, and associated settings screens, have been re-designed from the ground up to be massively more powerful and convenient to use.



The overall pitch of the organ can be adjusted from MIDI pistons on the organ console, control panels or menus, allowing the organ to be tuned to other acoustic instruments, or adjusted to match that of any real organ pipes driven by Hauptwerk as the temperature changes.


Audio & MIDI Recorder/Player

Capture your performances to 16-bit or 32-bit .wav files using Hauptwerk’s built-in audio recorder. Hauptwerk can record and play back MIDI files and can natively record and play back MIDI files, completely independently of any MIDI settings or hardware. You can record a MIDI performance using whatever MIDI or touch-screen hardware you have and send it to any other user of the same virtual organ.


Audio & MIDI Performance

Monitor audio levels, computer performance, memory usage, sound delay (latency), polyphony, sample rate and MIDI channel Input/Output activity. You can also adjust your polyphony limit and audio levels in real-time, making it a quick and intuitive way to get the best performance from your computer.



Register, Set and Save all of your combinations for any Hauptwerk instrument using the Intelligent Combination System™ and recall any of them instantly. Combination sets may also be shared between friends that are using the same instrument.


Master Couplers

Hauptwerk provides a palette of standard inter- and intramanual couplers (16′, 8′, 4′, bass, melody) for all virtual organs, in addition to whatever couplers they include natively.


Floating Divisions

‘Master floating divisions’ allow you to interchange up to five MIDI keyboards between multiple virtual organ keyboards in real-time. They can take divisional pistons and expression pedals with them, and you can even use them to switch the order of virtual keyboards assigned to your MIDI keyboards on the fly.



Hauptwerk provides sixty master scoped pistons in addition to any combinations or functionality a virtual instrument might include natively. You can configure each of them to affect any range (subset) of stops you wish, so you can make them behave as divisionals, generals, or perform any other special functions, such as ‘all trems off’, for example.

Theatre Organs

Now playing in a theatre by you.

Hauptwerk does theatre organs too.

Hauptwerk fully and accurately models theatre organs including unification, second touch, untuned and tuned percussion, toy counters and effects, sustain, reiteraters, crescendo, pizzicato, note by note tremulant modeling with tremulant voicing adjustments and much more.

Note for note reproduction.

Unlike many digital organs which only use one pipe recording for several notes and pitch stretch to “fill in the gaps”, Hauptwerk uses a single unique pipe sample for each note that is played. Chromatic pipe recordings offer all the nuances between individual pipes that you would hear just as you would from the original organ.

Original sampled acoustics.

Real pipe organs are designed and voiced for the acoustical space in which they’re installed. Reverberant or ‘wet’ virtual instruments capture and reproduce the natural acoustic and spatial characteristics of the original organ’s room, from each pipe’s position separately. It’s not just sampled acoustics, it’s the real acoustics!

Pipe and Rank Voicing

Total control over your sound.

Voice and Balance.

The Advanced Edition of Hauptwerk offers full voicing and balancing controls giving you the option to customize each pipe’s volume, brightness, tuning, expression, tremulants, wind modeling, stereo panning and EQ. Select a rank, then select the voicing parameter and adjust each slider as needed to voice or balance the instrument to your listening environment and your tastes.

Multi-monitor Displays

More space for more controls.

Launch up to 4 display windows.

Hauptwerk Advanced Edition supports multiple console views for use with two or more monitors. Support for up to 4 consoles views is available for virtual instruments that include them. Additional screen space can be used for Hauptwerk’s control panels, piston toolbars, the pipe and rank voicing screen as well as several additional organ console views.

Dual stop jambs.

Several Hauptwerk virtual instruments feature both left and right stop jambs with all of the organ’s controls available. With an appropriate dual monitor configuration you can have both stop jambs of the original organ console within arms reach offering an ‘at the bench’ experience. Hauptwerk can also change the screen orientation of a virtual console from landscape to portrait for instruments that include the necessary graphical layouts.

Multi-channel Audio

Stereo/mono to full surround and beyond.

Surround yourself with up to 1024 audio channels.

Hauptwerk Advanced Edition supports up to 1024 audio channels . Additional audio outputs can be added as required with just a few clicks when used with a multi-channel audio interface. The standalone version of Hauptwerk can drive up to 512 stereo or 1024 mono audio channels or up to 16 stereo channels via the VST/AU plug-in link.

Group selected ranks.

With an appropriate multi-channel audio interface and amplification, ranks of pipes, or parts of ranks, can be routed and amplified separately, and even pipes within a rank can be distributed across several audio channels providing a three-dimensional sound-field and reducing distortions within the amplification system for crystal clear playback.

Historic Temperaments

Stay tuned. In any period.

Selectable temperaments and original organ tuning.

Many historical tunings and temperaments are included with Hauptwerk, and can be recalled instantly from the organ console or via the control panels or menus. Original organ tuning is also available for virtual instruments that support it. Many Hauptwerk instrument developers also include special temperaments specific to the organ. Changing temperaments quickly and easily and in real-time offers organists an ideal way to listen to the music using a period temperament.
Equal temperament is also available and allows using Hauptwerk with music ensembles or choirs that require more standard tuning schemes.
Custom temperaments can be created and may be shared with others with an easy to follow installation into Hauptwerk.

MIDI Learn
Quick & Easy Set Up

Right-click. Auto-detect. Done.

Featuring native support for most makes and models of digital organs, MIDI Learn offers a quick and easy set up for your console without needing to know any complex MIDI settings. If you’re playing on a theatre organ, MIDI Learn will even set up second-touch automatically. If your console features MIDI output then it can play Hauptwerk already when connected to a computer and audio/MIDI interface. Spend less time configuring and more time playing.

Professional Audio

Core Audio & ASIO

HD audio and more.

Hauptwerk supports up to 32-bit 96kHz audio sample resolution, Apple’s Core Audio, and Steinberg’s VST and ASIO technology – the standards for professional audio, low latency and high performance.
Hauptwerk can also use Windows Direct Sound drivers, however for best performance ASIO drivers are the recommended choice when running Hauptwerk on Windows.

Software for Computer Musicians

Audio Unit & VST Plug-in Links

A new way to connect to your host.

The Hauptwerk AU/VST plug-in link changes the way you can use a highly optimized virtual instrument with your host program. Traditional VSTi instruments are limited in the amount of performance they can achieve when running within a Digital Audio Workstation’s own platform. To remove this limitation Hauptwerk itself runs outside of your AU/VST host as a stand-alone application and instead connects through the ‘Hauptwerk AU/VST Link’ in your sequencer providing a bi-directional bridge for MIDI routing as well as audio routing.
Running outside of the AU/VST host allows Hauptwerk to perform significantly better, and offers a richer user interface, integrates more tightly with digital MIDI organ consoles, works fully via touch-screens and for MIDI files to be independent of MIDI hardware and MIDI settings.
The Hauptwerk AU/VST plug-in link is included with the Advanced Edition of Hauptwerk in both 32-bit and 64-bit.
We’ve even created several detailed step-by-step tutorials for some of the most commonly used host programs available to help you get started right away.
