This is exactly what I was looking for. No ads I don’t think, I haven’t run across anyway. So only complaint is that there’s no way to tip you! :) Led display very cool touch by the way. ### 1/5 — What?… *2023-07-19* …No Seriously, What? This makes no sound let alone sense. Just get the Antares one, you don’t need an active autotune sub for it to work ### 4/5 — PLEASE BRING IT BACK *2020-07-03, version 1.2* This was very useful for those who don’t know music theory. Just holding the key down to lock it in and eliminate the keys that it’s not in is so simple but so effective! PLEASE BRING IT BACK ### 5/5 — PLEASE UPDATE TO 64bit 🙏 *2017-11-06, version 1.2* PLEASE UPDATE TO 64bit 🙏 ### 1/5 — Not very good *2013-02-04, version 1.2* Hard to use, very unclear ### 5/5 — Great app *2012-07-31, version 1.2* Great app ### 5/5 — Great Program! *2011-10-09, version 1.2* Once you figure out how to work it, it's sick! AUTOTUNE? you can find the key easy! ### 2/5 — Handy *2011-05-28, version 1.2* Can't play minor scales in Ref mode though... ### 5/5 — Great App! *2010-06-03, version 0* This is exactly what I was looking for to help my song writing. The only things I would change would be to label the notes on the piano keys, and to be able to move up and down the keyboard. ### 2/5 — Good idea but *2009-12-04, version 0* Who the hell would want this and not know major keys? MORE KEYS! this would be awesome if it was done properly. I want to make this app. More keys! Hundreds of them!!!! Please! ## Frequently asked questions about KeyFinder ### What does KeyFinder do?
