Does not work with Ionic framework on iOS

[frissonlabs]

This library does not work when used in an Ionic project and deployed on iOS (works perfectly on Android). This applies to all versions of Ionic. The attached screenshot shows the error message.

To replicate, simply generate an Ionic project, add the libraries, deploy it on iOS, and run the MIDI.loadPlugin(onsuccess); command, either through the Safari debugger console or as function within the script. The onsuccess function never gets called and the error appears.
