v
Verschueren reconstructed the Ibach organ

The monumental organ is built in the high Romantic period (1850 to 1890). At that time, the best romantic instruments were created, in which the delicate way of playing was applied to classical mechanical principles. The touch allowed the organist to play very nuanced. The beautiful sounds are excellent for performing the Symphonic works of Mozart, Brahms, Liszt and Schumann. The Ibach organ has 42 registers, divided into three keyboards and pedal. The disposition is almost identical to the original design by Ibach. However, a Bassoon 16' was recorded in the main work and on the third manual the Krummhorn was converted into an intimate sounding Euphone 8'.
The organ has a total of 2417 pipes.

New registers were invented and applied, such as the Euphone 8', the Flaut Travers 4' with overblowing pipes, intimate sounding conical Viola 8' and Viola 4', the Jubal 8' with double labia. The romantic Ibach organ offers an unusually wide range of solo registers, while a powerful and monumental plenum is preserved on the main work against a mild plenary on the side work.
The reverberation of the church is 7 seconds. On March 17, 2011, the organ was played anew.

The Ibach organ is representative of liturgical use in Brabanter Land in the second half of the 19th century. The symphonic nature of the organ is achieved with a wide variety of sounds. Registers of 16 and 8 feet give the sounds the necessary carrying capacity. The wide range of registers allows for dynamic differences in subtle steps. The soft pianissimo is made even more intimate by the use of a swell for the third keyboard.
These beautiful properties are transmitted correctly by the samples of Jiri Zurek.

Sample Set

The samples are offered in 48kHz/24bit resolution. The multiple releases have three levels: short, mid and long. Hauptwerk v. 4. 2 and higher supported. The sample set is offered in plain wave format. Hauptwerk Advanced version is strongly recommended for use, the Basic version is not suitable to run the Surround variant of the sample set (memory limitations, audio channels limitations).

SemiDry - the microphones were close to the organ case, almost attached to the front pipes, migrating from division to division. This variant contains the highest portion of the "dry" pipe sound, the reverb level is minimal, its length is still apparent, though.
The set costs €254,-incl. VAT

Surround -The microphones were arranged in the typical Sonus Paradisi setup. Two microphones captured the sound relatively near to the organ (but not as close as the SemiDry mics), other two microphones captured the sound at greater distance from the organ (diffuse sound) and two microphones heading away from the organ captured the response of the church (rear). In total, there are 4 front audio channels and 2 rear channels. The two front pairs can either be mixed together freely to achieve any listening position between the two extremes, favoring direct or diffuse organ sound, or used separately - depending on the prefererences of the user. A dedicated "mixing desk" is available in Hauptwerk to mix the sound to the desired level.
The set costs €508,-incl. VAT      see Sonus Paradisi

Rudolf & Richard Ibach  

Builder
of high romantic organs

The St. Gertrudis Church of Bergen op Zoom (Nld) was built around 1450. The organ was built in 1864 (at the time of the High Romanticism in 1850-1890) by the German organ builders Rudolf & Richard Ibach for St. Mary's Church in Mount op Zoom. It is a large romantic organ with 42 registers spread over three keyboards and pedal. The monumental case is a design of the Brussels architect Emanuel A. J. Cels.

In 1915, the organ was converted into a smaller organ with 25 registers. However, the old pipes were used for the two keyboards and the pedal. The swell disappeared and several registers were changed. In 1988, the organ was transferred to the parish of St. Gertrudis. The intensive use of the organ for the liturgy and concert performances required extensive restoration.

Organ consultant Jan Jongepier examined the organ in 1997 and declared it to be one of the most valuable organs from the time of high Romanticism.
Jongepier:  "An instrument of royal trait and unique to Europe "
However, a restoration to Ibach in its original form was necessary. In 2001, Jongepier made a restoration plan and Verschueren in Heythuysen was commissioned to carry out the restoration. The extensive work carried out by this precise restoration cost more than one million Euros.
