Prestant – Organ Tuner

Prestant is a tuner built specifically for the pipe organ – precise, fast and reliable even with soft stops. Organists, organ builders and organ consultants tune reeds, flue pipes and mixtures right from their iPhone or iPad. Prestant also handles piano, harpsichord and other instruments with confidence.

PRECISE DETECTION
• Measures to a fraction of a cent – display resolution of 1, 0.1 or 0.01 cents
• From the 32′ pedal (16 Hz) to the very top of the treble
• Picks up soft flutes from a distance, even with the swell box closed
• Calm, easy-to-read display without jumping digits – readable from the console

FIVE DISPLAYS
• Phase and needle free – strobe, spectrum and voicing (harmonic analysis) with "Organist"
• Large note name and cent value at a glance

HISTORICAL AND CUSTOM TEMPERAMENTS
• Pythagorean, meantone (1/4, 1/5, 1/6 comma and more), Werckmeister, Kirnberger, Vallotti, Neidhardt, Schlick, Silbermann and others
• Chart and interval table for every temperament
• Create and edit your own temperaments, freely adjustable concert pitch

BUILT FOR WORK AT THE ORGAN
• Compound stops: measure every rank of a mixture, cymbal, sesquialtera or cornet at once
• Rank by rank, the way organ builders work: the key is detected automatically, all readings in one table

• Celeste mode for voix céleste and unda maris
• Reference tone generator
• Organ projects with divisions, reference pitches and temperature compensation – synced via iCloud across your devices

FOR THE PIANO TOO
