If you need to work to a tuning reference other than A4=440 Hz, you can alter this using the Tuning Reference slider at the top of the Scales dialog. In this example the tuning reference has been altered to 444 Hz, which is used by some European orchestras, for example. The tuning shift is also shown in cents, in this case +15.8 (a cent being one hundredth of a semitone). The range is up to a semitone up or down from standard concert pitch.
