The WR-01S Wi-Tune from Korg is a wireless tuning system allowing you to tune a saxophone, clarinet, etc., in any situation, unobtrusively, accurately and easily. The wireless tuning systems come as a set, consisting of a transmitter that attaches to your instrument, and a main tuner unit that receives the wireless signal. This setup allows a great degree of freedom, letting the musician watch the tuning meter at a natural angle of sight without being tethered to the tuner by a cable.
Large, backlit LCD offers excellent visibility with pitch variance and note name shown in the large liquid crystal display for excellent visibility. Built-in backlighting assures tuning with confidence, even on a dark stage, or at a distance. The wireless status and the remaining battery amount are also clearly indicated by icons, providing this important information at a glance.
The main tuner body has a built-in microphone that allows you to tune your instrument without using the transmitter. The tuner also provides a Sound Out mode that produces an audible reference tone from the internal speaker, which you can use for tuning by ear, or for ear-training practice.
Inaccuracies of the harmonies in a triad are particularly easy to notice when played by an ensemble such as a brass band or orchestra. By slightly adjusting the pitch of a major or minor third relative to the equal-tempered interval, a pleasing pure third can be obtained. The meter scale of the Wi-Tune includes markings to indicate pure major and minor thirds relative to a specified pitch.
