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).
