 The way that iOS/iPadOS works, there can be only one audio input and one audio output device at a time. The OS automatically makes the last connected device the designated input and/or output device. If a device is input only or output only, it will take over whichever function it provides. Headphones with mics are input+output devices as far as the OS is concerned. Headphone dongles -- even if no headphones are attached MAY look to the OS like an output device. Some USB hubs have built-in headphone ports. These may or may not conflict with an audio interface unless the interface is connected after the system has booted.
+**Bluetooth Note**: if your interface is something like a SparkGo that can connect via USB or Bluetooth, use USB. Bluetooth audio (not MIDI) connections generally have too much latency for realtime music performance. Besides the latency, such devices may perform unpredictably with Loopy Pro when running in Bluetooth mode.

    * More than one audio output or input device is connected. Some MIDI peripherals with USB connections look to the OS like an audio interface. Make sure that your audio interface gets plugged in after your MIDI peripheral. You will not be able to use the audio capabilities of both your interface and another peripheral that looks to the OS like an interface at the same time and there is no easy way to switch between them other than plugging/unplugging.
+**Volume calibration project**. This {{ :loopy_pro:test_tool_levels_folder.zip | Test Tool}} can be useful in calibrating the output of your iPad or iPhone. It has two loops that send maximum or near maximum volume. Turn down your amplifier or mixer before playing the output as the project's files are potentially loud.
