Six Simultaneous Precision Strobe Tuners for your guitar. Fast. Accurate. Noise resistant. Can use the built-in mic on your iPad. With multiple simultaneous strobe tuners, you don't need to wait for your room or recording studio to become quiet enough. You don't need to wait for a tuner to lock onto each note. You don't need to wait for a needle to finish moving. If you're really good, you don't even need to tune one guitar string at a time. With multiple strobe tuners, you can see if one string shifts in frequency while tuning another. You can also see if plucking a string hard on your guitar causes the notes to "bend". Just watch the waterfall waveforms overlaid on each string. When the waves for a particular guitar string synchronize or line up vertically, and stop leaning and shifting left (flat) or right (sharp), you are precisely in tune with an internal equally-tempered digital oscillator. inTuna HD supports up to 4 custom intonation presets, where you can individually vary the reference frequency of each string in 1 cent increments (+-20 cents) from equal temperament, and quickly switch between your custom presets. The A440 master tuning reference is also adjustable from 415 to 455 Hz. 8 alternate tunings (Standard EADGBE, Drop D, DADGAD, etc.) are supported, plus a special bonus Bass Guitar and String Bass mode.
