Reyburn CyberTuner, the pro piano technician’s gold standard tuning software tool for over 22 years. Over three years in development for iOS including a year of intensive testing by master piano technicians around the world!



This is a professional piano technicians’ tuning tool and is priced accordingly. The 17+ rating reflects only the price. There is no Mature/Suggestive content, or any objectionable content of any kind. 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 member of the PTG with years of concert tuning and prep experience as well as “in the trenches” home tunings and repairs. The piano tuning knowledge base 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.



• New for iRCT! Concert Tune mode combines the best of Fine Tune and Smart Tune but customized for 7 foot (210cm) and 9 foot (275cm) concert instruments.



• NEW! 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).



• Faster and higher resolution spinner than ever before gives you unsurpassed stability and unisons.



• Occasional internet connection (once a month) required to calibrate A440.
