Standalone ipad crashing due to Microphone access

Just started receiving this message at startup, any ideas?

2017-05-31 23:55:48.626895+0100 MIDISynth-Circuit[3483:1058920] [access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSMicrophoneUsageDescription key with a string value explaining to the user how the app uses this data.

I don’t intend to be accessing the microphone and not sure of any changes I’ve made that would cause this to be the case…

Removing the {1,1} from the Plugin Channel Configuration has stopped this error happening.

If your plug-in is an effect plug-in (i.e. it has at least one input and output) then the standalone plug-in will apply your plug-in to the microphone input (or any other input connected to your iPad) and output it to the iPad’s audio output. By default, JUCE will mute the audio input to avoid a feedback loop.
