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 Middle East in their songs. Connect an external MIDI keyboard to your iPad, iPhone or iPod touch 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", Apple's "Inter-App Audio" System and the "JACK Audio Connection Kit" (up to iOS 6.1.3) 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 arabic 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

Ratings and Reviews

Fantastic App!

Ben Efitofadoubt

It's not just limited to exotic tonalities. It is also great for solid "English strings" (George Martin, Glyn Johns, Paul Buckmaster, etc...)

Incredibly versatile and worth every penny.

Sound probs

BK Holiday

Several of the instruments are the exact same sample. Exactly the same. I believe there is a bug switching the sounds in the app perhaps?

Developer Response

That is definitely not the case. Please read about the so called "multi-part" feature of this app. The following is a link to the iSymphonic manual, but it behaves the same with Oriental Strings:
From your description it sounds like you were triggering notes on another part then the one you were switching sounds on. For more questions please contact us:

Great app - Great support


I bought this app when it first came out, and I've used it on many tunes. The sounds are very rich and exotic, and they add drama and excitement to any production.
Recently, I had occasion to contact them because of an issue in a song I was arranging.
It was nearly 5:00 in the afternoon EST and I thought I'd probably hear from them after the weekend. 15 minutes later I received a reply that led to me solving the problem. The problem that I had created.
I consider that to be exemplary customer service!
An absolutely 5 star company.
