- Clear transport and system MIDI control mappings on CLEAR session.
- AUv3 main param knob: use AUParameter stringFromValue if kAudioUnitParameterFlag_ValuesHaveStrings is set.

- Don't show sample rate error message if it actually worked.
- Read AUv3 currentPreset property after init/stateLoad.
- Automatically mute input nodes if they change from external to built-in microphone, to avoid feedback.
