High-Quality Tracker Action Keyboards

The feel of the keys conveys the touch of a true Tracker Action. When using MIDI and Orchestral sounds, the keys instantly become touch sensitive and give the player the ability to be more expressive musician that you are.  For the more discerning player, the Chorum S80 is available with optional wooden keyboards or the exceptional AWK keyboard.



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.

- Music, for more than 100 years music has been our passion.

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 S80 is equipped with 96 sampled stops arranged in four banks, each with 44 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 S80 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 S80 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 S80 also includes a headphone socket should you ever need to play in total silence.



Extensive Connections

An extensive selection of external connections is smartly and conveniently located underneath the lower keyboard. In addition to the standard connections, MIDI In-Out, headphones and stereo inputs, there is also USB pen drive to save and upload sound settings, and for MIDI song recording and playback. Master volume and reverb controls are conveniently located on either side of the output panel.

On the rear of the instrument there are additional audio outputs: One subwoofer and two stereo for optional external speaker cabinets. The external audio can be adjusted with independent 7-band audio equalizers for each channel.
