ORPHEUS人声样本库项目于2004年启动，其使命是勾勒保加利亚人声之谜的传奇。为实现这一目标，制作人 Ivan Kovachev 邀请了几代保加利亚最好的专业合唱团、声乐团体和独奏家，展示该国的传统声乐宝藏。该系列中包含的乐器补丁将真实的巴尔干氛围带入任何风格的音乐创作、电影配乐和混音中。三部曲中包含的所有人声样本都是“干”的，只带来录音室大厅的原始声学氛围。 ORPHEUS 样本库在保加利亚制作，包括录音、音频设计、乐器编程和 UI 设计。衷心感谢参与该项目的所有专业人士（合唱团、声乐团体、独唱歌手、声乐专家、指挥和组织者）。
The ORPHEUS vocal sample library project was started in 2004. Its mission is to outline the legend of the mystery of the Bulgarian voices. To make that happen, the producer Ivan Kovachev invited several generations of the best Bulgarian professional choirs, vocal groups and soloists to present the traditional vocal treasure of the country. The instrument patches included in this collection bring authentic Balkan ambience into any style of music compositions, film scoring and mixing. All vocal samples included in the trilogy are “dry”, bringing only the original acoustic ambience of the recording studio hall. The ORPHEUS sample library was made in Bulgaria including the recording, audio design, instrument programming and UI design. Sincere thanks to all professionals (the choirs, vocal groups, solo singers, vocal experts, conductors and organizers) who took part in that project.
