INSTRUMENT BACKGROUND A pipe organ is not something you see every day, there are thousands of different pipe organs that differ by the number of stops, the number of manuals, the number and the type of pipes, their size, their position, etc. Cantoria is a Baroque-style organ based on a single manual and 9 stops plus 3 couplers and the classic "tremulant" effect. This type of organ has "only" 776 pipes, which Cantoria simulates one by one. It doesn't sound "massive" like bigger organs, but is very dynamic and can vary from a soft delicate flute sound to a loud and majestic. vibrant full organ. This synth engine works as an hybrid synthesizer, uses additive synthesis and physical modeling together, there are no samples involved. The expression pedal responds naturally and varies the amount of air that passes through the pipes.
