The virtual instrument boasts the Pusztaszabolcs’s two 45-note manuals and a 15-note set of pedals. All keys and keyboards are shown in a photo-realistic perspective view, fully responsive to mouse control. The manuals and pedal keyboard all faithfully mirror your performance.

Short octave

Some historical instruments, such as the Pusztaszabolcs organ are built with a lower short octave. This means that some keys produce different sounds than in other octaves. The following pictures show the two types of historical key responses.

	Historical Mode historical key response (original)
	Extended Mode full key response (MIDI-compatible)

The same short octave response applies to the pedal keys as well.

In the Extended Mode the keys are fully functional and responsive according to the MIDI keys. This is achieved by electronically re-creating the notes that were missing, based on the available notes.
