GSi Cantoria is a physical modeling emulation of a Baroque-style Pipe Organ. 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. About the name: the name we chose for this plugin "CANTORIA" is the italian name of the place, inside a Church, where the organ and the choir are located.

Relic Waves is a generator of Lo-Fi noises, pads and effects based on unique synthesis algorithms from NightRadio. More than 4 billion samples from the depths of the Mathematical Universe! Features: * search for new sounds with three buttons: next random set, edit code, previous set; each set of 12 sounds corresponds to a code of 8 characters; * three types of keyboards for live performing: on-screen buttons, PC keyboard, MIDI input; * several processing parameters + control via MIDI; * real-time audio recording to WAV (32-bit); * export to: WAV (one file or a set), SunVox (samples + effects in one file), text clipboard; * the LCK button freezes individual samples - they will not change during the search for new sets; * iOS Audio Unit Extension (AUv3). Double clicking on a parameter opens a window for setting the exact value. If you enable the Hold option, the notes will play endlessly, without reacting to key release (noteOff) events; turning the note on again works like turning it off; there are two ways to enable this option: 1) using the Hold parameter in the "MIDI Mapping" window; 2) by pressing the HOLD button, which appears in place of LCK while playing the musical keyboard: press HOLD, release the desired notes - then the released notes will continue to play.
