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. An iRCT license includes Standard Mode (ability to tune a 13 note temperament from A3 to A4) plus a FREE one (1) year subscription to CyberCare which upgrades the mode to Premium (tune 88 notes). Also included with a CyberCare subscription are free upgrades to any new iRCT features, CyberCloud calibration, and support. See "In-App Purchases" for CyberCare price in local currency. If your CyberCare Subscription lapses, iRCT will continue to function in original Standard mode. In subsequent years CyberCare one year subscriptions may be purchased in-app with automatic renewal option: – Payment will be charged to iTunes Account at confirmation of purchase. – Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. – Account will be charged for renewal within 24-hours prior to the end of the current period. – Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. The iRCT software includes a single user license. iRCT may be used to tune pianos (or any keyboard instrument) on one and only one iOS device at a time, but may be installed on multiple iOS devices.

  • Pitch Perfect Piano Tuning

    By 2uneUp
    Great program! Love the app!! Pitch Raises in minutes, not hours, Keep the upgrades comin. Thanks!
  • Great program

    When I started tuning a few years ago, the app was great. Now, understanding all the aspects of it, it has been the results astounding. The app easily! Pays for itself and the quality result is well worth the investment. The P12 option has allowed me to generate insanely neat results on spinets and pianos commonly thought of as “junk” - a few calculations, and voila! Even “ye olde” sounds great. Not to say, it also has helped tremendously to have sub-bass option when tuning Bosendorfer Imperials.

  • The Quintessential Tool

    By Crane 440
    I’m a concert technician of 20 years...4-5 concert venues per week. Tune mostly Steinways for C&A, store and in customers’ homes. I would never have made it to where I am today without this tool. It is a “must!”

    I am a professional piano technician with 37 years experience, and started using Cybertuner almost 20 years ago-not long after Dean developed it for Macintosh. (Haha, I think I still have the floppy disk somewhere- serial number 73). I lugged my laptop to work for years so I could use RCT. With each new incarnation of the program I eagerly upgraded- with development of the Windows version I moved to a Pocket PC (which by the way I struggled with, being a Mac guy). But RCT on that device was a seamless transition. And when iRCT was announced I was overjoyed! Now my iPad mini running iRCT and FileMaker Go accompany me everywhere there is a piano, and there are a lot of them in my life. I owe much of my success to Reyburn CyberTuner. Thank you Dean!
