The main tuning screen includes both a versatile Spectrum Display and a fine tuning strobe-like display we call the Phase Display. The Spectrum Display shows a selected portion of the frequency spectrum with a peak in the graph at each pitch. The central red line in the Spectrum Display is the tuning target. The note is in tune when the peak in the graph is exactly on the red line. The Phase Display is like a strobe-type display where a band of moving boxes move to the right if the note is sharp and to the left if the note is flat. The goal in tuning with the Phase Display is to make the pattern move as slowly as possible, and ideally to stop entirely.
Since air temperature affects the pitch of organ pipes, we provide a means of compensating for actual air temperature, in case the temperature at the time of tuning is not exactly the same as it will be for performance. This is usually done in aural tuning by establishing a "golden pipe" that is not changed and referencing all pitches to the pitch of that one pipe. We can reference a "golden pipe" too by means of the Locking function which offsets the pitch of all notes a given amount. But we also have a more direct way to do it using actual temperature readings in Celsius or Fahrenheit, as described in our manual. The actual temperature readings can be established in two ways. One is manually by the user by entering the reading from an ordinary thermometer. The other way is automatically by the use of one of the supported Bluetooth temperature sensors.
"Tempo Pebble" and "Tempo Disc" sensors from Blue Maestro
"myBlue-T" temperature sensors by WeatherHawk
(discontinued by the manufacturer, but we still support it if you have one)
"Moat S2" temperature and humidity sensor from Moat
"Govee H5074" thermometer from Amazon
"Govee H5174 and H5179" directly from Govee. (H5174 is preferred because it is Bluetooth only.)
"Inkbird IBS-TH1" temperature sensor from Inkbird
