Domus P33 is equipped with keyboards “Tracker Action” 2 x 61 notes covered in real dark wood, to achieve that “real feeling” sought by every organist, in fact, the feel provided by the keyboard is just that of the best mechanical traction. In addition, the Tracker Touch effect, mixed with detailed algorithms, will give you an unprecedented organ experience. Touch sensitivity is also particularly useful with orchestral voices or MIDI.



Domus P33 is equipped with Physis Plus technology, the powerful natural evolution of the well-known Physis that, thanks to the system Moris© (Viscount Deep Learning), it has made possible to achieve a sound credibility never achieved before. In fact, it is able to capture and elaborate new parameters typical of organ sound, making our physical models incredibly realistic.



A complete selection of external connections is smartly situated. In addition to Standard connections (MIDI In, Out, Thru; Headphones, stereo inputs), there is a microphone with gain control, 4 external multiple outs + Sub – with the option to expand these to 12+1(Sub). There are also USB host and Device connections. For the USB Host connection, it is possible to use a thumb drive to save and upload sound settings. For the USB Device connection, you can connect to a PC to personalize all aspects of the organ. With the free “Physis Plus Editor” for PC, you can modify every single voice for every single note – including volume, pitch, spatial disposition – and many other parameters.



Domus P33 has one expression pedal that provides a fluid and precise movement – allowing complete control of the volume for Manual II and the Crescendo – programmable up to 16 levels.
