The ultimate orchestra sound app for sophisticated musicians by award-winning sound designer Kurt Ader, designed as professional sound module for your iPad, iPhone or iPod touch by connecting an external MIDI keyboard, using the Apple USB camera adapter or another adapter supported by Apple.¹

Listen to the demo videos on our product website!

This app supports Audio Unit, Inter-App Audio and Audiobus for audio & MIDI connections from/to other audio apps, as well as Bluetooth LE MIDI !

iSymphonic Orchestra was designed with the goal to deliver you superb, extremely realistic and stunning orchestra sounds, instantly with the first key being pressed by you on your MIDI keyboard. Just select a sound and you are ready for your live performance or for a boost of creativity while composing new songs. The sounds used in this app were explicitly recorded to fulfill these requirements and involved several months of recording and post processing under supervision of Kurt Ader and included a variety of innovative, new recording techniques. So far these sounds were only available to very few, famous movie composers. Now they are finally available for the first time to everybody. The supreme quality of these sounds, combined with the unique way they were recorded and assembled, gives us confidence that you haven't heard anything comparable as of to date, even not on Mac or PC.

Stunning sounds and great response using ipad4, Alesis iodock and old midi keyboard(Yamaha Np30). I only discovered this app because I downloaded midi wrench by the same developer. Not all sounds are top rate but the ones I plan to use (strings, full orchestra, string ensembles) are incredible. Great buy and highly recommended!

Good app, small fix required


It is a good app however I am not able to select the last preset in the scrolling window list when used as audio unit. I tried numerous times. I have an iPad Pro. Hope it can get fixed.
Thank you !

Please contact us at and let us know which DAW app and which iOS device model you were using. Thanks for your feedback!

Great Sounds, but unusable for Live gigs


Reason: there is an issue with middle E, F, & F# samples, where the Violin Rosin (colophony) comes through too loud (sounds high-pitched, like a sine wave). That is the response from the developer I got, in a very timely matter, last year. (Originally, when I bought this app Sept 2017; just before Version 2)

I was hoping, for Version 2, they would fine-tune these samples, and perhaps, remove or give an option to lower the string resonance volume (heard mostly in the upper register.)

Hopefully they'll get better beta testers in the future, that will catch these sort of issues.

Using Ipad Air 1, OS 9.3, IRig MIDI 1.

Developer Response

Thanks for your review! Like we already explained on your support request; this is not an error, it is the natural sound of the violin's colophony that you hear in those specific sounds.
