Features
Drop tuning needs a stable answer.
When a tuner jumps around on the lowest string, you are no longer tuning. You are guessing. LockOn is built to hold the pitch read long enough to make the next move obvious.
Note readout
Shows you the note that LockOn has detected.
Strobe
Rotates based on how flat or sharp a note is. Your job is to tune your instrument to get it to stay still.
Cents display
Shows how many cents flat or sharp you are.
Calibration
Set your reference pitch here.
Audio mute
Sets whether or not the audio signal passes through the tuner.
Settings

Something magical physically happens when you tune an instrument perfectly. I tuned 8 instruments to absolute perfection using LockOn - including a 5 string electric cello, 5 string electric violin, an 8 string guitar, two 7 strings, three 6 strings, and a 5 string bass. This tuner now lives in every template I use for composing music.

I always have a hardware strobe tuner in front of me, and LockOn is even more accurate than my hardware! You know how you hit that low F# on bass and your pedal tuner starts having a seizure or gives you the silent treatment? Not anymore, LockOn is fast and stupid accurate! No longer will we have to suffer through the quarter-tone-sharp octave chords in your latest pop punk masterpiece, because now you have a sick tuner and you have no more excuses. Now take this and fix that damned G string!

I've never experienced such an accurate, easy to use and pleasant to look tuner. As a metal bass player I can say that it doesn't miss a beat on very low tuning and slow mode makes it even more precise.

LockOn is honestly a real pleasure to use. The tuner is accurate and stable and doesn't wobble around in a glitchy way, which can often happen with low tunings. I especially love the Slow mode, it's so smooth! Tuning your guitar while recording is never fun, but this plugin can make your life just a bit easier. Ultimately, that's what it's all about.

This tuner is a massive life saver for recording our music. It is easily the most responsive and perfect tuner that accurately tracks low tunings with extreme precision. Definitely already a staple in my workflow. Bless you SubMission Audio.

LockOn tracks low notes better than some physical tuners on the market that actually cost money. This plugin is a no brainer if you own a guitar or bass.

I can't handle how good this tuner is.

Fà quello che deve fare , io avrei messo anche qualche preset per accordature non comuni
this a great tuner that parallels real tuners that guitar techs and luthiers use to attain precise intonation for guitars. I will definitely be using this going forward!
Never had a tuner so accurate on 8 string guitars. Can't be happier than that.
I've used the free version for a while and loved it so much that I bought the full version during a sale. I could have kept using the free version, but it was time to support Submission Audio for their hard work and great product.
Everything is in the title. For me the best guitar tuner ever !
A strobe tuner without the strobe tuner price.
