Virtual completeness through quality and quantity

Even with a staggering 1.5 million samples, not all combinations of tones, playing techniques and their interactions can be recorded. The secret of the Vienna Symphonic Library lies in creating nuance through clever combinations of samples. Using intelligent and revolutionary native programming to manipulate both single note samples and Performance Elements, the composer is able to create fluid, lifelike passages, bringing all of his ideas to life simply and efficiently. The Vienna Instruments' unique Performance Detection algorithms and the most powerful audio-engine on the market enable the user to play these Performance Elements in real-time.

Sample structure example: Brass instrument

  Single Notes       Performance Elements

Single notes without dynamic changes

  • Chromatically sampled
  • Alternative samples – several different samples for each playing technique
  • Up to 6 different dynamic levels per pitch (pp to ff)
  • Different tone lengths (staccato, portato, marcato, sostenuto)
  • Smooth, normal, hard embouchure (attack)
  • No vibrato; slight, strong, progressive vibrato
  • Special playing techniques such as flutter tonguing, lip trills, muted

Single notes with progressive dynamic changes

  • Chromatically sampled
  • Different tone lengths
  • With and without vibrato
  • Dynamic changes: increasing, decreasing, increasing and decreasing
  • Degree of volume change:
    pp–p, p–mp, mp–f, f–ff and vice versa
    pp–mf, mf–ff and vice versa
    pp–ff and ff–pp
  • Sforzato
  • Sforzatissimo
