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. 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.
