Sleek, compact console

The modern console boasts a sleek, compact design. The Studio will definitely not look out of place in a 21st-century music or living room. It comes in four beautiful colors: Light Riverside, Black North Wood, Nautilus Teak, and Wenge. Its fresh, modern design lets the Studio blend into any interior setting. Because it does not take up much space, the organ will also find a spot in smaller music and living rooms.

Signature sound

Thanks to the ingenious technologies used in the Studio 150 and 350, it is virtually impossible to hear any difference between this digital organ and a pipe organ. This primarily comes down to the high quality of sound, which we spend each day perfecting at Johannus. Even experts are unable to distinguish the sound of an authentic pipe organ from our digital organs. Partly due to our new, in-house technology, the purity and authenticity of the organ sound can be heard in each individual note. Thanks to our on-going quest to emulate the original pipe organ sound and to find the best way to reproduce that sound, our entire range of products will help you reach the pinnacle of musical artistry. As do this Studio 150 and 350.

Four styles

The Studio 150 and 350 feature 28 and 37 stops respectively, but the variety does not stop there. After all, each stop can be played in four different styles, and an 8’ Röhrflute played in the romantic style sounds completely different than when played in the historical style. If you enjoy playing Bach, you will favor a baroque style, while Widor’s compositions sound more natural in the symphonic style.

Twelve reverb programs

The Studio 150 and 350 each feature 12 unique reverb programs as well, which lets you augment your organ playing with virtually any acoustic effect that you could think of. You might imagine yourself playing in an intimate chapel, or even sitting at the manuals of an organ in an ancient cathedral. With a choice from four different sample styles and twelve reverb programs, the Studio gives you access to a wide range of pipe organs and building types within the four walls of your own music or living room.

Versatile and affordable

With all these possibilities, the Studio offers unparalleled versatility to novice and advanced organists. High-quality sound, respectable dispositions, various styles and multiple reverb programs, all packed in a compact console at an accessible price: the Studio in a nutshell. A true Johannus to fit any music room!
