Is there a way to modify sound parameters in Noise for iOS?
It is possible to access several parameters when Noise sounds are used in GarageBand for iOS but it seems there is no way to edit parameters in Noise (which seems a waste of resources if the functionality is already available to 3rd party apps such as GB).
Is there a way to do that?
Yes, these parameters are accessible in GB but sadly, GB cannot render Noise sounds when you export a song. So, it's kind of a dead end until the bug is fixed.
It's really curious that GB has access to those parameters while their native app Noise has not.
