这是Best service公司引以为自豪的管弦乐音色库，Peter Siedlaczek经典的高级管弦乐系列，采样音色中经典。虽然相对于今天巨型容量的管弦乐音色库真实度欠，但是当年的音色制手段就是在容量小的限制下作出最好的音色。计算机性能不太好的制作者强烈推荐。

Peter Siedlaczek's Advanced Orchestra for Akai consists of five CD-ROMs containing well over five thousand samples of all the instruments and instrument groups of a large symphony orchestra. Sustained and staccato notes on two dynamic levels are provided along with a variety of frequently used phrasings and articulations, which cannot be satisfactorily imitated with normal samples. For example, half or whole tone trills, various grace notes, runs, arpeggios, tremolos, crescendos, glissandi and other events, playable in any key or pitch.

All of the staccato notes and some other events in the Advanced Orchestra set are sampled twice. If a quick repetition of the same note is needed, they can be used alternately. The result is much more natural. Also included are a collection of unconventional sounds such as scratches, whistles, thumps, buzzes and other effects, which can be modified in many ways, for adding new color to compositions. Additionally, the user-friendly CD-ROMs contain numerous, carefully looped samples.
