Use Tuner utility and plug-in in Logic Pro for iPad
You can tune instruments connected to your system with the Tuner utility or plug-in. This ensures that external instrument recordings are in tune with any software instruments, samples, or existing recordings in your projects.
If you’re new to using plug-ins, see Intro to plug-ins. Also see Add, replace, reorder, and remove plug-ins in the Plug-ins area and Work with plug-ins in the Mixer.

If the indicator moves to the right of center, the note is sharp. Color is also used to indicate tuning accuracy, with green denoting a tuned signal, orange indicating a slightly detuned signal, and red indicating an out of tune signal.
