Specification and screenshots of the Antegnati organ in St. Carlo, Brescia

Features

  • 24bit, 48kHz samples, multi-sample technology (each tone has 3 independent samples which are chosen at random for playback each time the key is pressed - this results in greater variety of sound).
  • Virtually noiseless - no disturbing noise in the samples or in the reverb.
  • Multi-sampling (up to 5 independent attack samples per single tone for more vivid sound - each time you press the same key, a different sample can play back for a given stop)
  • Multi-release (up to 4 release samples for a single attack sample depending on how long you keep the key pressed - it effectively removes the known "staccato effect".)
  • Original (short-octave) and Extended (chromatic bass octave) versions of the sample set available.
  • Other features of the sample set are described on the Features page.

RAM consumption

  • Hauptwerk single release, 16-bit, full reverb, compressed: 1 839 MB
  • Hauptwerk multi release, 16-bit, full reverb, compressed: 2512 MB
  • Hauptwerk, multi release, the highest quality loading (24-bit): 3.1 GB
  • MyOrgan (with memory compression): 732 MB

Compass

  • manual  - 4 and half octaves (MIDI: 36-C to 89-F). In the original version, the lowest octave is "short", meaning that it is only diatonic C-D-E-F-G-A-B-H. In the extended version, the chromatic semitones were added.
  • pedal - 20 keys (MIDI: 36-C to 55-G), 12 pipes (high octave repeats the low tones), hard coupled to manual

The ranks of traditional Italian organs break at about 1/6' or 1/8' pipe length an octave down making an octave repetitions. This produces a preponderance of 2' and 2 2/3' pitches in the upper part of the compass of the Ripieno. For further information, see the C. Jonson's or Barbara Owen's book mentioned in the history section of this web.

Historical tuning is lost, equal tuning is applied to the organ now. However, by using various tuning charts available in Hauptwerk 2 or 3, you can retune the instrument to the desired historical tuning.
