Sound Generation

Powered by Viscount's newly designed ARTEM Sampling Technology

The entire CHORUM line uses proprietary ARTEM technology (Advanced Real TEchnology Music).

- Advanced, we have advanced our sampling and computation capabilities.

- Real, the resulting sound is exactly like a real pipe organ.

- Technology, we use state of the art digital sound generation technology.

This powerful  sampling sound generator has been designed by Viscount in Italy to faithfully reproduce the authentic sound and performance of a traditional pipe organ. 

The Chorum 50 is equipped with 152 sampled stops arranged in four banks, each with 38 own unique set of voices. These enable you to choose between Baroque, North German Baroque, Romantic and Symphonic. You can easily select the various styles as well as create your preferred acoustic environment.

The Chorum 50 offers a choice of eight different acoustic room models. You can therefore select the optimum ambience for your style of playing by matching the acoustic environment to the historic organ of your choice, all at the touch of a button.



High Fidelity Amplification

The internal amplification of the Chorum 50 has been designed to give you an incredibly large and robust sound right out of the box.  It's also designed to give you remarkable sonic excellence right down to the lowest frequencies, even whilst set at the lowest volumes for small spaces.  The 5 speakers are driven by a 3 channel amplification system:  2 x 60 Watt + 1 x 100 Watt.

Audio outputs are available to connect additional external amplification, should this organ be installed in a church, or to give an even more pipe-like experience in the home.  The Chorum 50 also includes a headphone socket should you ever need to play in total silence.
