Oriental Strings is a professional sound module app for oriental keyboard players and for musicians who simply want to resemble the typical sound of the Orient and Middle East in their songs. Connect an external MIDI keyboard to your iPad, iPhone or iPod touch by using Bluetooth MIDI or by using the Apple USB camera adapter or another adapter supported by Apple, or launch Oriental Strings as virtual instrument directly within your favourite DAW app on your iOS device!¹ Watch and listen to the demo video on our product website! This app supports "Audio Unit", "Audiobus" and Apple's "Inter-App Audio" System for audio & MIDI connections from/to other audio apps, as well as Bluetooth LE MIDI ! The sounds of Oriental Strings were exclusively recorded with players who are professionally dedicated to oriental style of music. Typical string instrument sounds for the Arabian genre are covered by this app. Besides rather exotic instruments like the Chinese erhu, typical western string instruments were used as well, but since the players of the recording sessions are focused on oriental music, those western instruments sound completely different than you might be used to from western orchestra players. The sounds of this app were once again created by Kurt Ader, winner of the NAMM 2015 "Best Sound Designer of the Year" award. 32 Sounds are included with this App: • Chinese Erhu 1 - 3 • Chinese Erhu Trill • Turkish Strings 1 - 4 • Arabian Strings 1 - 3 • Tremolo Strings 1 - 5 • Spiccato Strings • Oriental Spiccato Strings • Oriental String Quartet 1 - 3 • Oriental Staccato Strings • Arabian Solo Strings 1 - 3 • String Quartet • Oriental String Ensemble 1 - 5 • Slow Oriental Strings There is no in-app purchase in this app. So all sounds and all app features are immediately available to you as one buy.
