Organ Tuner

This app is for professional pipe organ builders and technicians. It addresses the special tuning needs of building and maintaining pipe organs. Notable features: * Covers the note range of C0 (32' pipe) to C9 (1/16' pipe) * Handles mutation ranks (Quint, etc.) and Celeste ranks * Built-in compensation to track temperature changes during tuning * Calculates pipe cutoff for trimming new pipes to length * Precision strobe-like display for very precise tuning * Has multi-pitch mode for tuning mixtures without cottoning off any pipes * Pitch accuracy is 0.02 cents * Many historical temperaments for period music are available * Switches notes automatically up to 4 notes away * Provides a versatile display of the frequency spectrum * Wireless control of MIDI-enabled organs for key holding and stop selection using a Bluetooth MIDI adapter. Organ Tuner has two different displays that are visible at once. One is the strobe-like Phase Display. This is a band where black squares move left or right. You tune to make the squares stop moving. The other is a frequency Spectrum Display. This is a graph that shows a peak for every pitch present in the sound. You tune to make a peak in the graph move to a central red line. Having both the Phase Display and the Spectrum Display visible at once gives you a more complete picture of the tuning than any single spinner-type or needle-type display. There is an extensive built-in context-sensitive help system in the app. A detailed user's manual is also available at our support web page.
