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 Vienna Synchron Stage. 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.
All the instruments were recorded using 20 microphones, subdivided into 11 sections. The Standard Library includes 4 of these sections (as well as a RAM-friendly Room Mix section composed of merged samples from the individual positions), allowing you to integrate instruments recorded with a stereo Decca tree into your projects using the Vienna Synchron player or our mixing hosts Vienna Ensemble and Vienna Ensemble Pro. Adding the Extended Library and thus getting the Full Library expands your possibilities to 5.1 surround and Auro 3D 9.1, with the additional option of High Stereo and Surround microphones to expand your sound possibilities even further.

For each ensemble, there are a number of Mixer Presets that depict different recording situations. The basic Mixer Presets in this Collection are Close Solo/Center/First Chair, Classic Solo/Center/First Chair, Wide, Distant, Ambience, Lush, and Lush Long. These are available in stereo versions for Room-Mix, Standard and Full, as well as in Decca Tree Multi Mic and Surround Presets. Moreover, there is a Special category for the Full Library.
By default the classic room mixes are loaded which include the Standard Library microphone positions “Room Mix”, “Tube” and “Mid”. These are balanced in the stereo field to represent the respective instrument’s position in the Synchron Stage set-up.
Patches can be used to build your own custom Presets and adapt the Synchron Libraries to your specific requirements. For further information on constructing Presets, please see the Synchron Player manual.
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, you may mix your instruments in Auro 3D as well as in Dolby Atmos.
The Presets of each instrument group are subdivided into 9 (violin) resp. 10 (cello) different Articulation categories:
- Short notes
- Long notes
- Performance legato
- Dynamics
- Tremolo
- Trills
- Pizzicato
- Harmonics
- Effects (cello only)
- Sequences
The new category “Sequences” presents a feature allowing you to play a pre-defined sequence of Articulations. The Articulation categories are further subdivided into Types such as spiccato or staccato, and additional options are available for most Articulations, e.g., attack or release variants.
Synchron libraries generally offer different Presets according to how velocity is handled, arranged in separate folders.
“VelXF sus - MOD”: velocity crossfading is only activated for long notes, while the dynamics of short notes are controlled by keystroke velocity, thus facilitating phrasing. “VelXF - MOD”: all articulations have velocity crossfading activated so that you can control dynamics with MIDI controller CC1, the modwheel. “VelXF + Velocity control”: these Presets also use the modwheel, but in addition keystroke velocity is used to determine the attack behaviour of long notes, legato, etc. Moreover, there are special patch combinations, e.g., where velocity triggers spiccato or staccato samples. “Velocity”: note volume is controlled by keystroke velocity just like a piano.Velocity crossfading can always be enabled or disabled by clicking its on/off symbol in the Synchron Player's Perform tab.
The Presets of each instrument group are subdivided into different articulation categories, including one named “Custom” and ready for your own creations. Within these articulation categories, you can select a type, e.g., staccato, and for some of the types there are additional options available, such as “bold” and “agile” for the Introduction / Pitch staccatos. Depending on articulation, there also may be things like release and crossfading options. If you happen to be short of RAM, you can leave the entire dimension tree disabled and only enable the slots you need for your arrangement.
Switching between an instrument’s playing styles and articulations is generally done via dedicated keys on the keyboard and aptly called “keyswitches”. By default the keyswitches for Articulations are mapped depending on an instrument’s range – starting from C1 (for Middle C = C4). The violin’s Type keyswitches start from C2, and those of the cello from C6.
Dimension Controllers offer additional options within some Articulations or Types, most notably that of crossfading between different Patches. The controller function is indicated by the group’s respective caption, as of course it may take on different tasks as needed.
The Presets of the Collection comprise all the instruments’ recorded Patches in Articulation groups, which again contain Types of the respective Articulation, with further options if available. If you happen to be short of RAM, you can leave the entire dimension tree disabled and only enable the slots you need for your arrangement.
The violin’s Articulation keyswitches are mapped from C1 to A1 (for Middle C = C4), those of the cello from C1 to A#1. The Type keyswitches start from C2/F2 (depending on articulation) for the violin, and from C6/F6 for the cello. The keyswitches for further options such as release and attack variants are mapped to the keyboard’s 7th octave.
Dimension Controllers offer additional options within some Articulations or Types, most notably that of crossfading between different attack and release variations. The controller function is indicated by the respective caption, as of course it may take on different tasks as needed.
