The ERS DimD chorus audio plugin was originally designed and sold by Harrie Munnik and his Dutch company EmptyRoomSystems. DDMF is proud to carry on the legacy by distributing and further developing the set of ERS plugins. This plug-in has been developed to sound like the Roland Dimension D Chorus with enhanced controls (a hardware chorus that has been used on thousands of recordings worldwide). It has its own signature sound: it is famous for delivering a subtle, stereoizing enhancing, airy effect while adding more presence to a sound. Most chorus products give a lot of modulation and do not keep the original structure of the sound intact. This chorus is way more subtle and adds something rather than take away the original quality of the sound.
