Heppenheim (HEP) Pipe Organ Samples is a fully playable, freely configurable, intuitively manageable and MIDI-controllable virtual pipe organ for the Hauptwerk™ virtual pipe organ software, for PC and Macintosh computers, delivering the sound of the 43-stop Wilbrand symphonic pipe organ of the Saint Peter Church, Heppenheim, Germany, to your computer.

The sample set

The real pipe organ has been entirely virtualized, including all sounds of all of its pipes, all functions including the original tracker sounds are provided, allowing realistically sounding repetitive notes. With the KeyboardMass functionality, the inertia of the mechanics of the key action is modeled. By providing the additional feature of adjustability the response speed of the pipe speech when a key is released can be changed to your taste. Thus you can make the keyboards feel very heavy by increasing the slider values, or extremely responsive by decreasing.

Sample format

The final sample set has been made available in 48 kHz / 32-bit 2-channel stereo. Multiple, lengthy loops were carefully selected for each sound sample.


The natural church acoustics representing the recording conditions are embedded in the samples with multiple release sample layers; the acoustics heard in the sample set corresponds to the sound heard in the church. The sample set is recorded in a way that it is also fully compatible with dry acoustic spaces and additional convolution reverberation.

Multiple release samples and multiple loops

Multiple loops and release samples are provided for each sample. Triggered to play back randomly, this elaborate looping results in sustained notes of unmatched realism. The loops were calculated in a well-planned way, yielding both shorter and longer loops for each sample. Multiple release samples provide realistic, note-off-triggered pre-recorded reverberation for different lengths of notes. For example, a short note, with sound not fully developed will produce a different reverberation than a long sustained note. This quality is preserved in the sample library by providing multiple release sample layers.

Hybrid tremulants

Stops with the tremulant engaged were recorded separately on this pipe organ. Some of these stops are included in the sample set as 'sampled tremulants', while others - using a proprietary analysis method - were included using LFO-based tremulants. This hybrid model supports using the minimum amount of additional RAM and polyphony while providing a rich tremulant sound.

Advanced Graphical User Interface (GUI)

The graphical interface of this organ was carefully modeled by employing hundreds of photographs and measurement in full 3D and the interface was implemented in a non-orthographical, perspective console view that is fully photo-realistic and operational at the same time. The keys move while you play, and every button responds appropriately to your actions. Both multiple- and single-screen operation is possible: the large number of stops can be operated conveniently from a wide choice of interface pages displayable on multiple touchscreens. Alternatively, convenient single screen operation is also provided.

The organ and the church

The first reference of the St Peter's Catholic Parish Church situated in Heppenheim is dated back to the year 755, named as Basilica Sancti Petri. The present church was built between 1900 and 1904, designed by Ludwig Becker. The monumental neo-Gothic church is also known as Cathedral of Bergstaße. This name earned by being visible from kilometers around and from the famous Bergstraße Route ("Mountain Road").

The new church maintained and integrated the old tower while is made up of three naves, one transept and the choirs including a main choir and two side choirs. The long nave and the transept reflects the enormous dimensions of the church with the crossing in the heart of the building. After the Second Vatican Council the church has its first renovation period between 1968 and 1969. The interior of the building is changed by removing the pulpit and moving the lithurgical center to the crossing. The centre of the sanctuary is dominated by the altar. During the restoration in 2002, the pulpit was rebuilt in its former shape, a new ambo was put up under the dome and the baptismal font was also moved here.

The first of the four previously known organs is built in 1700, and damaged by lightning in 1703. The repaired instrument was destroyed in a church fire in 1732. The new organ, built in 1742, did its service until the demolition of the church in 1900. The next pipe organ, which was a small intstrument, was designed for the temporary church - later town hall - in 1900 by the organ builder Voigt. In 1904, this organ was built in the new church, the "Cathedral of Bergstraße".

There were plans to build a larger organ from 1909, but the First World War and the economic crisis allowed only in the 30s to think of the construction of a new organ. The church contracted with the organ builder company Klais, Bonn, but the contract was terminated in the Second World War.

In 1955, for the 1200th anniversary of city of Heppenheim, a new organ was built by Kemper from Lübeck. This instrument was kept reasonably playable until 1996. Then this organ was dismantled and replaced by a new organ by the organ builder Wilbrand in 1997, integrating the still usable pipes in it.

The west window of high artistic value had to remain free, so the pipes are arranged in separate cases. The Hauptwerk and Schwellwerk are on the left, the Pedalwerk is on the right, and the Rückpositiv is on the balustrade of the gallery. The organist sits with his back to the case of the Hauptwerk.

The disposition of the new organ is almost the same as the Kemper organ. It has 43 stops on three manuals of 56 notes and a 30-key pedalboard. The pipe scale and the intonation emphasize the dark richness of sounds, so the instrument is suitable to play romantic as well as symphonic music.

System requirements and recommendations

It is intended (and required) that the Heppenheim Pipe Organ Samples be operated within Hauptwerk, a virtual pipe organ host software application (purchased separately). The Heppenheim Pipe Organ Samples work with Hauptwerk V and later, and a valid license for Hauptwerk is required to load the organ.

System requirements for the Heppenheim Organ
Host software
Hauptwerk version V or later
Advanced Edition is recommended, Basic Edition is required
i7 or Xeon or better is recommended
Dual-Core or equivalent is required
Sound card
ASIO compatible recommended

The Trial Edition requires the presence of a Hauptwerk USB key with a valid license for Hauptwerk.

For further information, please refer to Hauptwerk's detailed requirements on Hauptwerk's website.

Detailed RAM and polyphony guidelines

Hauptwerk loads all samples in the computer's RAM, with several loading options available according to your computer's specification. For wet sample sets offering built-in long reverberation, most of the RAM usage is due to the release samples. If you have convolution or other reverberation technology available, less RAM and polyphony will allow you to load and play the full organ. If you have more RAM, you can load the full organ with the release samples and enjoy the original sound. We recommend using Hauptwerk's built-in lossless memory compression to reduce the loading size. Below we have summarised the RAM requirements with their corresponding quality options.

*The Required RAM column above is the memory requirement that also includes Hauptwerk*'s own memory consumption, so this represents the RAM the sample set and Hauptwerk* together will use, but some additional RAM may be required for the operating system itself, (not included in these figures). The measures were obtained on a Windows-based computer. The Computer RAM column shows a recommendation on the amount of RAM your computer should have as a minimum for a given loading setup assuming that some additional RAM is used by the operating system. This value might be different for each case so we recommend the maximum possible amount of RAM installable in your computer for this sample set, except if you are working with external reverberation or in a dry acoustic environment. Also note that on the Mac you may require more RAM in the computer than the value indicated above, due to the Mac OSX RAM allocation behaviour. Also note that Windows is capable of loading more content than your available RAM, loading (paging) the additional sample data to your hard drive, reading it once the sound is needed (played). In some cases this will cause glitches in the sound when played in real time since the hard drive is slower to access than the computer's RAM, but makes the full library usable in offline music composition and recording even if you do not have the required amount of RAM.



Hauptwerk V platform

  • Hauptwerk V license is required for the operation of the sample set
  • No license update or activation procedure is needed to use this sample set

This sample set comes in an encrypted format compatible with Hauptwerk v5. Both the full and the Trial editions of the sample set require the presence of a Hauptwerk v5 evaluation, subscription or perpetual license.

Modifications and customization

If you are planning a custom or commercial application that requires a different setup what this sample set offers out-of-the-box, please contact us for making a customized version for you. 

Modification or disassembling the contents of this sample set through the CODM interface of Hauptwerk is not supported since the variety of functions and the availability of the sample set's certain special features already offers most of the functions the CODM interface may offer. The complexity of the Organ Definition File shipping with this sample set is uniquely high and building custom variants requires a certain amount of special expertise. Legally, the end-user license of this sample set is permitting using the samples as a whole, as they ship.
