A veritable household name among organ enthusiasts

The impressive history of the Opus extends back to sometime in the last century. To be exact, it dates back to the 1970s, when the Opus came onto the market as the first Johannus living room organ. Since then, countless organists have grown up with this organ and “the Opus” has become a veritable household name among organ enthusiasts.

The Opus sounds like an authentic pipe organ

Because the Johannus R&D department is responsible for developing all of the technologies used in the organ, these technologies are perfectly attuned to each other. This ensures that the organ responds rapidly and consistently to what the player asks of it. At the merest touch of the keys, the authentic sound of a pipe organ resonates through the room. Just as it should.

Every touch produces a beautiful sound

The Opus owes its beautiful sounds to the Harmonic Contour Sampling method used by the sound engineers at Johannus. First of all, they make high-quality recordings of leading pipe organs. They then select the best-sounding pipes from an organ stop and use these to form the foundation for the entire organ stop. At every touch, the organist can enjoy the exquisite sound quality of these impressive pipe organs.

True-to-life wind and pitch

Opus organs incorporate a wide range of advanced technologies. For example, the Virtual Pipe Positioning system simulates the actual location of the pipes in the pipe front, and the wind model developed by Johannus provides a realistic representation of the organ’s wind supply. This means that the pitch fluctuates very subtly when a number of keys are pressed simultaneously.
