This is a sneak preview of Orchestral String Runs – a string library designed for creating individual, energetic string lines.
With the OSR – RUNS BUILDER, you are able to create your own runs, based on several figures and structures recorded with an huge orchestra. The Runs-Builder is only one part of a bigger sample-library.
