The WERSI OAS (Open Art System) digital organs are truly amazing instruments capable of producing hundreds of different sounds and effects. This showcase will take you on a tour of these instruments highlighting all the features that enable them to replicate anything from a small jazz trio to a full concert orchestra. An explanation of these features is provided and the accompanying audio examples, played live with no multi-tracking, will demonstrate their use in a variety of musical styles. So whether you are an existing player, or aspire to be, or just enjoy listening to music, I hope that you will find the showcase interesting, informative and above all entertaining. Let’s have some fun as we explore the wonderful world of WERSI.

The Showcase Playlist

All the Showcase music has been recorded directly from the audio outputs of the Wersi organ using a Tascam DR-680 digital recorder, and monitored on a set of Beyerdynamic DT 880 headphones. To hear the true authentic sound of the instrument it is recommended that you listen with these headphones, or others of an equivalent quality.
