The user interface includes the following tabs:

  • a main console with drawstops, keyboards, pedals and effects;
  • a “big jamb” interface, without the console window, designed to suit touch screen usage;
  • an “alternate interface” with stops actioned by buttons instead of levers and a standard screen combination set of 10 general memories;
  • an “enhancements” tab with some options and settings, see section below for details;
  • an “organ info” panel with the description on the organ distributed on different tabs;
  • various photos selectable with buttons at the footer of the screen page.

All the layouts described above are screen responsive to both 4:3 and 16:9 ratios.

Keyboard splits: For greater compatibility with the organ literature of different epoques and schools, the Sampleset is provided with two additional keyboard splits: B2-C3 and C3-C#3 (the original split is C#3-D).
Pedalboard: Real pedalboard extension is C1-E2; for more flexibility the pedalboard extension is set to 2 octaves. The second octave of the pedalboard is permanently coupled to the first octave of it. Player can limit the extension to the original one via MIDI pedal settings in the Organ Settings/Keyboard options or right-clicking the pedalboard in the Console interface.

“Terza Mano”: In the real organ, the Terza Mano is activated both via hand drawstop and F2 pedal, as per typical configuration in organs of that period. In this sample set, the F2 pedal is set to play the corresponding note instead. In case the player wants to activate the pedal per exclusive use of Terza Mano effect, he can:
1) right-click on the pedalboard in the Console interface screen, choose Auto-detect function, and set C1-E2 extension for sounding pedals pressing the corresponding pedals in the real pedalboard;
2) right click on the Terza Mano lever in the Console interface screen, choose Auto-detect function, and press the F2 of the real console pedalboard.
All the above configuration steps can be achieved following different procedures than the ones reported here.

“Combinazione libera alla lombarda” – Free combination:
A duplicate set of stop buttons has been added to the interface in order to keep the role of this device in the virtual version of the instrument.
The organist can prepare a single combination of stops activating the buttons in the COMB. LIBERA sections. Once prepared, the combination can be activated (or deactivated) actioning the COMB LIBERA button/lever on the interface. The stops of the combination will be added (or detracted) to the stops already playing.

HauptWerk’s Wind Model is applied to sampled pipes in order to match real pipe organ wind dynamics. The effect can be reduced or deactivated if desired. Please consult standard program documentation at this regard.


The fifth tab of the interface offers the following options in order to improve the playing experience:

· Three different stereo perspectives are available with specific level control: Direct, Diffuse and Rear;
· Mechanical noise (Meccanica): this control provides the desired noise sound volume quickly (stops, keyboards and other devices);
· Blower noise (Motore): this control can sets the sound level desired. The Blower can be activated or deactivated with the switch on the main Console or on the additional tabs.b Please note you will need to activate the switch in order to play the instrument as it simulates the switch of the blower.
· The Chiff level slider provides a pseudo-random system to pipe speaches. Setting the slider to the minimum, the effect is progressively reduced to just one chiff. This is a «light effect» with the intention to add natural speach to the piping without alterating the character of the instrument.
· The Release slider is a pseudo-random effect that shuffles 3 different releases for each release timing. As for the above, this is a light effect.
· Organ Detuner (Accordatura): this slider applies progressive pseudo-random detuning to the samples, incrementing or decrementing their relative pitches, with different levels between treble, bass, flues and reeds.
· Keyboard Split (Spezzatura): this device will provide the option to set 3 different keyboard splits:
C#-D is the original split and the default one. For greater compatibility with the organ literature of different epoques and schools, the sampleset is provided with two additional keyboard splits: B2-C3 and C3-C#3.
· Pedal to Manual (Unione Tasto-Pedale) coupler disabler: the real organ has pedals always coupled to manual keys, this option will toggle the device. In order to allow easy access to this enhancement during performances, the control has been replicated on the Console screen, Big Jamb and Alternate console.
· Bombarda 12’ to 16’: this is an option that substitutes the first five 8’ notes of the original stop with 16’ samples, obtained from samples of the same rank.

The pitch of the sampleset has been set to 440Hz – equal temperament while the real organ is set to 454 Hz @ 18°C Tartini-Vallotti temperament.
