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

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.

Amazing Sounds!!!! BUT..Not yet an full AU with GB

Demons Oppression

Crashes with GarageBand... Some sounds wont merge, sounds change from what you originally record. Audio engine stops every 5 have to reload the whole program then find the sound you were using. Just bought these all in app purchases very disappointed with this as an AU.
But the sounds are Amazing. I contacted the company and got an immediate response clarifying it has issues that were being addressed and (This issue would be fully repaired by the up and coming update.) That makes this the best app for IPad Pro sounds available IMO.

Equipment - Working on fully expanded 2018 IPad Pro.



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


It is a good app and it has great sounds. The sound libraries are pretty large and it takes a little time to switch presets, however that is the only limitation I can think of. Highly recommended !!
