Antares ATR-1 Auto Tune

The ATR-1a is a rack-mountable hardware implementation of Antares’s Auto-Tune pitch correcting software. Like Auto-Tune, the ATR-1a employs state-of-the-art digital signal processing algorithms (many, interestingly enough, drawn from the geophysical industry) to continuously detect the pitch of a periodic input signal (typically a solo voice or instrument) and instantly and seamlessly change it to a desired pitch (defined by any of a number of user-programmable scales).

In addition, the ATR-1a, befitting its easy portability, includes a number of new features that make it particularly powerful in live performance situations. These include a new Song Mode that lets the ATR-1a follow even the most complex harmonic song structures, foot switch control of Scale selection and Bypass Mode, as well as MIDI control of every ATR-1a parameter.
