Synchron Percussion I


Welcome to the Vienna Symphonic Library’s series of Synchron Instruments! The instruments were recorded at Stage A, the main hall of Vienna’s revitalized Synchron Stage Vienna. The recordings were executed using an expansive, phase-controlled multi-microphone set-up, capturing string effects played in a scoring stage with exceptional acoustics, now ready to be used in your studio. This document will provide you with the information you need to use the Library with our Vienna Synchron Player.

Standard and Extended Library

All the instruments were recorded using 12 microphones, subdivided into 7 sections. The Standard Library includes 4 of these sections, allowing you to integrate instruments recorded with a stereo Decca tree into your projects using our new Synchron Player software. Adding the Extended Library and thus getting the Full Library expands your possibilities to 5.1 surround and Auro 3D 9.1.

Microphone positions

Standard Library

  1. Close Mic - Mono
  2. Mid Layer Mic - Stereo (L/R)
  3. Main/Room Mic - Decca Tree Stereo (L/R)
  4. Main/Room Mic - Decca Tree Mono (Center)

Extended Library

  1. Main Surround - Stereo (L/R)
  2. High Stereo (3D) - Stereo (L/R)
  3. High Surround (3D) - Stereo (L/R)

The instrument Presets also include different mixer presets. By default the classic room mixes are loaded which include the Standard Library microphone positions. These are balanced in the stereo field to represent the respective instrument’s position in the Synchron Stage set-up.

Immersive Sound and Auro 3D

Auro 3D is an immersive audio technology that allows for three-dimensional sound perception. The Belgian company Auro Technologies developed this technology based on a special speaker configuration, adding four additional speakers to a 5.1 surround configuration. These speakers (so-called "Heights'') are situated above the front and surround speakers and generate acoustic reflections that are perceived naturally due to the fact that sounds originate from around as well as from above the listener. Thanks to the comprehensive selection of discrete audio channels with the Full Library of Synchron Percussion I you may mix your instruments in Auro 3D as well as in Dolby Atmos.

About Pitch

For designating pitch, the Vienna Symphonic Library uses International Pitch Notation (IPN), which was agreed upon internationally under the auspices of the Acoustical Society of America. In this system the international standard of A=440 Hz is called A4 and middle C is C4. All pitches are written as capital letters, their respective octave being indicated by a number next to it. The lowest C on the piano is C1 (the A below that is A0), etc.

The Synchron Player software allows you to set middle C to C3, C4, or C5 according to your preference. Selecting another setting than C4 will of course also change the play ranges and keyswitches accordingly.
