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.

SL Tune is a vocal pitch-correction and tone effect for iPhone and iPad. Insert it on a vocal track in a compatible AUv3 host. Choose a key and scale, or select the allowed notes yourself. Natural mode preserves small pitch movements, Hard gives faster correction, and Robot locks pitch to the selected root across octaves. Six controls shape the sound: Retune, Humanize, Formant, Snap, Echo and Mix. Formant changes the tonal balance. Mix blends processed and original audio. Start with one of six factory presets: Classic Hard, Trap Lock, Silk Vocal, Clean Fix, Robot Grid and Echo Adlib. Save and load your own presets locally. The resizable interface adapts to portrait, landscape and compact host windows. Use SL Tune as an AUv3 effect in a compatible music host, or open the standalone app to preview and adjust the controls. Pitch correction works best on a single vocal line. It is not designed to tune a complete mix or separate voices from background music.
