Johannus Opus Choir Collection

The Opus Choir is the familiar Opus, made suitable for accompanying smaller groups such as choirs or gatherings of up to 150 people. The organ is available in a two-manual and a three-manual version. Since the Opus Choir is equipped with external speakers, it finds its way into any room. The authentic pipe organ sound of the organ, combined with the singing of an ensemble, choir, or congregation, makes for a gorgeous combination.

• 4.1 audio system (internal or external)
• Authentic pipe organ samples
• Style-variable disposition
• Four sample styles
• For rooms seating up to 150 people

The Opus Choir features four sample styles: romantic, symphonic, baroque and historic. In each style, stops from specific pipe organs come to life. For example, the ‘romantic’ sample bank features stops from the Ruffatti organ from the Church of the Epiphany in Miami. In the symphonic sample bank, the organist hears the sounds of Adema (Raalte) and Cavaillé-Coll (Paris). The historic sample bank breathes the Hinsz organ of the Bovenkerk in Kampen and the Baroque sample bank consists solely of samples from the Silbermann organ from the Katholische Hofkirche in Dresden. Whatever music is being played or sung, this organ always sets the right tone and gives a true pipe organ experience.

To do justice to each stop and each style, a disposition was chosen that links specific stops to a particular style. Some tab stops therefore have two stop names. For instance, in the ‘historic’ style, the organist has the Terzian (Hinsz organ, Kampen) at his disposal, while a Cornet can be played in the romantic, baroque, and symphonic styles using the same tab stop. In the baroque style, each manual has a full Principal choirs that are completely present, making the plenum grand and radiant. The Flûte Harmonique and extra string stops like the Gamba 8’ and Salicional 8’ are included in the symphonic style. Thus, the Opus Choir ensures that the organist can vary endlessly and showcase the unique sounds of each different style.

The Opus Choir is based on OranjeCore+ technology. This technology guarantees a fast start-up time: turn the organ on and it is immediately playable. Also, its excellent sound quality and long-term reliability contribute to the organist’s confidence in the instrument. For the organist who likes to prepare with headphones, the Opus Choir offers an immersive stereo experience. The ambiance function also allows the organist to choose from which position in the church the sound is experienced: from the organ bench, or the front, center or back of the church. In short, the Opus Choir guarantees stable technology, lots of possibilities, and a beautiful sound.
