High-Quality Tracker Action Keyboards

Chorum 40 is equipped with 2 x 61 notes “Tracker Action” keyboards. We understand the importance of having the right feel to the organ keyboard so have taken the utmost care in using the very best components. 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, Chorum 50 is available with optional wooden keyboards or the exceptional AWK keyboard.



Powered by Viscount’s 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.

Chorum 40 is equipped with 124 sampled stops arranged in four banks, each with 31 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.

Chorum 40 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 40 has been designed to give you an incredibly large and robust sound right out of the box. It is 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 at home. Chorum 40 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 stereos for optional external speaker cabinets. The external audio can be adjusted with independent 7-band audio equalizers for each channel.



1 Expression pedal and Crescendo pedal

1 expression pedal provides a fluid and precise movement – allowing complete control of the volume for Manual II and the CRESCENDO – programmable up to 16 levels.
