ALTUS organs, powered by the versatile HAUPTWERK virtual pipe organ (VPO) technology, are exact models of existing pipe organs. With cutting-edge audio, computing, midi and recording technologies, various historic pipe organs built by the likes of Batz, Cavaillé-Coll, Grygar, Hinsz, Marcussen, Skinner, Walcker and Willis to mention a few, are playable as virtual instruments with an unprecedented pipe sound realism on ALTUS organs. The VPO technology represents a landmark departure from traditional digital organ building. It ushers in the modern era in the industry, presentng an avant-garde but highly sustainable organ solution.

MODULAR DESIGN
The ALTUS organ design platform is modular, employing off-the-shelf hardware and software components. This brings about a revolutionary product effectiveness:
-
Upgradeability: With the use of off-the-shelf upgradeable hardware and software parts, operating within a modular design, ALTUS organs keep pace with the changing world of technology. Hence, obsolescence, a major problem in the organ industry is irrelevant to ALTUS organs.
-
Durability: ALTUS digital organs are primarily maintained via a part “replacement” culture as against a “repair” maintenance culture. This is most easily facilitated by the ALTUS modular design. And given the unceasing obtainability of off-the-shelf and upgradeable audio, computer and midi components, ALTUS organs are guaranteed to run into the future, redefining the longevity component in the digital organ industry.
-
Customization: There is the flexibility to custom-build ALTUS organs using different quality-price ratios. An ALTUS instrument can therefore start as a budget 2-manual organ that will develop into a luxury end 3 or 4-manual organ in the future. Likewise, a stereo audio system can grow from 2 channels to 512 channels for multi-channeling, sound distribution (volume power) or antiphonal setup.
-
Tonal Flexibility: Sampling of exisitng pipe organs around the world as software add-ons is unending. Thus, different organ tonalities from the Baroque, Symphonic, neo-Baroque to the Modern are available from the English, Continental and North America organ traditions.
-
SOUND QUALITY
By cashing in on the fast speed and large memory of modern computers, ALTUS technology processes ALL the pipe sounds of an existing organ with precision (32-bit 96 kHz audio sample resolution). With this, and a real-time voicing capability, a pipe organ sound quality never attained in the digital organ industry is achieved.
-
RELIABILITY
ALTUS organs are high-power computing machines to which the exceptional reliability standards of 21st century computer technologies apply.
-
MODERN CONSOLE
ALTUS consoles are minimalist in design. The space-saving concept feature adjustable touch screen monitors for easy stop control, configuration access and flexibility. However, traditional consoles with tab or draw stops are available.
-
