Weinheim (WHS) 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 Steinmeyer symphonic pipe organ of the Saint Laurentius Church, Weinheim, Germany, to your computer.

The organ and the church

The St. Laurentius Church is in the center of the old town, on the marketplace of Weinheim. The roots of today’s town church date back to the 8th century, when the chapel “Maria in the fields” was built in the same place. In 1293 Hedwig von Swende donated a new church, dedicated to the Mother of God. Evidence of this can be found on a grave stone and a memorial stone inside the present church. Around 1700 AD, the church was consecrated to St. Laurentius. Late 17th and early 18th century the church was rebuilt and a steeple was built in 1848.

The old church was always facing to east, so the choir was directed to the marketplace. Between 1911 and 1913 a new church was built with rotated orientation, according to the plans of Ludwig Maier. Only the tower was retained from the old building, now standing in the new choir edge. In 1964-65 the church was renovated in the style of that time. Until 1994, many changes have been undone and the church was restored.

The three-aisled basilica was the last executed construction of architect Ludwig Maier. The architecture follows its environtment. The terrain is heavily sloped from the direction of the choir in the west to the front facade at the market place in the east. Therefore, the choir is increased and the porch in the west has two large staircases. At the corners of the porch, statues of Apostles Peter and Paul are placed. The golden figure of Patron St. Laurentius stands in the center.

After the currency reform, the community of St. Laurentius Church decided to build a new organ. The main part of the old organ was built in 1870, so the wood had become worm-eaten and the air pressure was no longer sufficent for playing. In addition, the sound of the instrument was too weak for the large church.

A completely new organ was built by Steinmeyer, Oettingen. The company was known of their pipe organs designed with meticulous care and their masterful voicer Hans Roettger. The instrument was one of the first major new organs in the postwar West Germany, with a fine tonal adjustment to the acoustic properties of the church. The pipe organ was played the first time on Palm Sunday, 1950. In 1982, the organ was extended and renovated.

The pipe organ has 43 registers with nearly 3000 pipes, on three manuals and a pedalboard. Speaking lengths of the smallest pipes are only a few millimeters long, the largest one is almost five meters. The physical organ’s tonal output is capable of challenging the limits of human hearing perception.

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 sample set comes in a Hauptwerk-specific encrypted format requiring a Hauptwerk USB key, compatible with Hauptwerk 4.0, 4.1 and later. Modification or disassembling the organ contents through the CODM interface of Hauptwerk is not supported since the variety of functions, the large number temperament data and the availability of the special built-in perspective adjustment already offers most of the functions or more than what the CODM interface may offer. The complexity of the Organ Definition File shipping with this organ is fairly high and building custom variants requires a certain amount of special expertise. If you are planning a custom or commercial application that requires a different setup what Weinheim Pipe Organ Samples offers now, please contact us for making a customized version for you.
