6.4.3.4 Special Configuration function: Stems
The Stems concept is unique to the Studer Vista.
For Film style mixing, bits and pieces of film sound are put together from a
variety of surround formats, ranging from mono to eight channels. Very often,
there may be hundreds of audio sources that need to be mixed together and
put into the right spatial image. In order to bring some order to such a vast
number of sources and formats, a concept of Stems is often used.
A Stem is a group of sounds (i.e., audio summing buses) that belong together.
Stems can be 1-channel to 8-channel wide.
For example, a console may be configured to have: 2 × Stereo stems for music,
3 × LCR stems for simple effects, 1 × 5.1 stem for effects, 1 × Stereo stem
for dialog etc., 1 × 8-CH stem for effects, 2 × Dolby Surround (4-CH) stems
for predubs.
The basic Stem setup is defined in the Session Configuration – the number,
type and assignment of Stem buses is fixed. In the Studer Vista GC, there are
controls for dynamic Stem setup and for assignments of the related recorder
tracks. In this way, the Stem setup may be changed dynamically as the need
arises. The restriction to the total number of Stems is the number of buses
for a certain Session Configuration. Studer Vista Master, Mono Group and/or
Track buses are used to build a system of Stems (each stem consists of a
number of buses) up to a maximum of 104 Stem buses at any time.
