High-Quality Tracker Action Keyboards

Cantorum Duo 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 Voices, the keys instantly become touch sensitive and give the player the ability to be more expressive musician that you are.

Cantorum Duo uses proprietary ARTEM technology (Advanced Real TEchnology Music).

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

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

The Cantorum Duo is equipped with 108 sampled stops and 15 orchestral voices arranged in four banks, each with 27 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 Cantorum Duo 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.



High Fidelity Amplification
The internal amplification of the Cantorum Duo 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 4 speakers are driven by a 2-channel amplification system: 2 x 40 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 Cantorum Duo also includes a headphone socket should you ever need to play in total silence.

In addition to the standard connections, MIDI In-Out, headphones and mini-jack stereo inputs, dual audio output, there is also USB pen drive to save and upload sound settings, and for MIDI song recording and playback.
