CyberTuner8.7.6 - App Store

Reyburn CyberTuner, the pro piano technician's gold standard tuning software for over 30 years. Continuously refined through three decades of professional feedback from master piano technicians.
This is a professional piano technicians' tuning tool. We expect users to already know piano tuning basics and have their own tuning equipment.
What makes Reyburn CyberTuner for iOS (or "iRCT") superior to other tuning software? Ease of use. Clarity of functions. Intuitive and thoughtful design and programming by a Registered Piano Technician (RPT) member of the PTG with years of concert tuning and prep experience as well as "in the trenches" home tunings and repairs. Built on the collective knowledge of scores of RPTs. Flexibility to tune the way you want with unbelievable accuracy. Support by the creator, by either personal email (international) or toll-free phone (in the US & Canada) for registered users. Email listserv support is free for registered CyberTuner users.
. Concert Tune mode combines the best of Fine Tune and Smart Tune, customized for 7 foot (210cm) and 9 foot (275cm) concert instruments.
. Aural Tutor expert system analyzes your aural tuning and suggests intervals and check notes for improving your aural skills.
. Extraordinarily accurate and fast pitch correction with iRCT's Smart Tune and Pitch Raise modes. These modes use a US Patented expert system to individually predict every note on the piano.
. iRCT creates aural-quality tunings by directly matching sampled partials, just as concert aural tuners do.
. iRCT accommodates all experience levels, giving beginning tuners a very simple interface, but offers advanced tuners customizable stretch choices.
. iRCT is an "expert system" which automatically senses and compensates for short scaling in spinets, small grands, etc.
. iRCT creates musical tunings from low bass to high treble because accurate multi-partial samples (to .01¢) are taken across a wide array of sample notes (A1, A2, A3, A4, A5 and A6).
. Fast, high-resolution spinner provides unsurpassed stability and unisons.
. New: Apple Metal graphics framework for improved battery life and responsiveness.
. New: CyberAssist built-in tech support provides instant answers 24/7.
. New: iCloud Sync with merge files feature keeps your files safe.
. New: CyberEar AI Mode creates tunings which challenge even the best aural tuners.
. Occasional internet connection (approximately once a month) required to calibrate A440.
