Opera 250 is a two-manual organ, 32-note new generation pedalboard, equipped with 33 stops (+ 6 orchestral). Ideal for the advanced organist, Opera 250 incorporates the Physis Plus Editor (free) that will allow the user many customization operations both in terms of generation and sound diffusion. The Tracker Touch effect has been improved, giving a pleasant “real feeling” never had before. It is also mixed with the Tracker Noise that adds some details of woody noise typical of the mechanical organ. The dual front woofer amplification system with a sustainable Class D digital amplifier saves electricity for maximum efficiency. The reverberation system has been completely redesigned as a real TRUE STEREO reverb, with numerous editable parameters and more slot presets for the user. Opera 250 has all the new Pipe sets made by Viscount, with the possibility to customize them with numerous additional orchestral voices.

The drow-knobs to turn stops on and off, the thumb pistons and all the other commands are ergonomically designed to respond quickly and easily to the demands of the user.

The layout is smartly integrated with the instrument to allow unlimited possibility and personalization at the user’s fingertips.



Knowing the importance of the classic-organ keyboard, we have taken the utmost care in selecting the absolute best components. The result is a consistent touch and at the same time comfortable, in addition, this keyboard is also sensitive to dynamics, a useful feature for both the Midi and Orchestra section, both to obtain the effect “Tracker Touch” which regulates the transition of attack of the rods with respect to the speed of pressing the keys.



Opera organs are equipped with Physis Plus technology, the powerful natural evolution of the well-known Physis, incorporating all the improvements of the new technology that, thanks to the system Moris© (Viscount Deep Learning) it has made possible to achieve a sonic 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 and conveniently situated. In addition to Standard connections (MIDI In, Out, Thru; Headphones, stereo inputs), there are a microphone with gain control, 12 external multiple outs + 1(Sub) – with the option to expand these to 20+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.



Opera 250 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.
