Motivation
Trying to find a specific style for your arranger is surprisingly difficult, and trying to find a free high quality style is nearly impossible. The styles are spread among abandoned enthusiast homepages, random zip archives, old forum threads, and commercial stores.
Every arranger owner has to start their style collection from scratch collecting files from random sites and asking for help on misc forums hoping someone can share the desired file. Even if someone wants to share their collection with the world, there is just no place to do it.
Over the years there were attempts to create different archives of style, but they all were relying on a project owner single-handedly maintaining their collection year after year, which inevitably gets abandoned sooner or later once the owner moves on.
