The multiple unique high contrast waterfall strobe visuals will quickly display the tuning in any of 12 note pitches and harmonics simultaneously. With 12 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 note at a time. With multiple strobe tuners, you can see if one pitch shifts in frequency while tuning another. You can also see if plucking a string hard on a guitar causes the notes to "bend". Just watch the waterfall waveforms overlaid on each string. When the waves for a particular note synchronize or line up vertically, and stop leaning or shifting left (flat) or right (sharp), you are precisely in tune with an internal equally-tempered digital oscillator. If you are not sure if you understand using a waterfall strobe tuner, please download the Free inTuna A440 app from the App store (which can only tune 1 note: concert A = 440 Hz) and give it a try. For custom intonations, you can individually vary the reference frequency of each string in 1 cent increments up to +-30 cents away from equal temperament. The A440 reference is also adjustable. Notice: This app plays no piano sounds! It only allows you to visualize pitch from the microphone input. ## Key features - 12 simultaneous visual strobe tuners - Fast, accurate, and noise-resistant tuning - High contrast waterfall strobe visuals - Displays multiple notes and harmonics - Adjustable reference frequency - Custom intonation support ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/ichromatic-strobe-tuner-hd/id397630582/reviews.md ### 4/5 — Excellent, all pupose tuner. *2011-09-20* The 12 simultaneous tuners is a bit of a gimic. Due to harmonics, the strobes for notes other than the one sounding seem to show a tuning match - or near match. Never the less, with the widget on the right side accurately identifies the fundamental, so the tuning is fast and accurate. The reference can be shifted from A440 to between 415 Hz to 455 Hz. The auto-octave works very well. So far I have seen no reason to lock it down to one particular octave, but I like that the option is there anyway. One of my favorite features is the ability to un-equal the tuning temperament. The menu lets me choose "custom" or "equal". When in "custom", each tone of the scale can be shifted +- 35 cents. And the "custom" setting are remembered even if I switch to "equal". It would sure be handy if there was more than one "custom" memory - and some common temperaments as presets would be nice too. Youngs, Kirnberger, Vallotti, Pythagorean, and meantone would be a decent short-list. Because it will do any note, it works for any instrument. Banjo, ukulele, bagpipe, etc. However it's up to me to know how the instrument should be tuned. ### 5/5 — Wow! *2011-01-20* I'm very impressed with this tuner. The graphics are good and the sensativity is excellent. Worth the price. ### 5/5 — Very good app. *2010-12-24* This tuner works very well. It reacts instantly, and is not bothered by background noise. It responds slightly to other musical tones in the room, but apparently, not enough to affect performance. As a violin student, I use it while practicing scales and playing pieces. The quality of the note can be instantly seen during play. I lock rotation and place the iPad on end on the music stand. Seeing the keyboard laterally is more intuitive for me. The "waterfall" is easy to interpret. ## Frequently asked questions about iChromatic Strobe Tuner HD ### What is iChromatic Strobe Tuner HD used for? iChromatic Strobe Tuner HD is used to visually tune any musical instrument by displaying 12 simultaneous strobe tuners.
