Description

From the listing uploaded by “appupdater”.

SOUND LIKE THE PROS! The tune-bot tuning calculator will help you determine the notes and frequencies to reach your perfect sound. Based on your drums and your personal preferences the tune-bot will provide recommended settings based on musical intervals. You can then use the tune-bot drum tuner to tune your drums to these exact settings. Also you can experiment with other tunings and try some of our “pro tunings” from the various tune-bot artists. After you’ve tuned your set to your liking you can save the pitches of all your drums to allow you to quickly re-tune to the same sound over and over again. No more guesswork! The tuning calculator app includes: • Drum-Set calculator • Snare Drum calculator • Bass Drum calculator • Single-Tom calculator • Store and Recall of multiple Drum-Sets • Pro Tunings from tune-bot Artists • Tuning Guide • Tuning Videos *THIS IS NOT A DRUM TUNER! It is a tool intended to be used with the tune-bot drum tuner. **The tune-bot drum tuner is available worldwide in music stores and online. See www.tune-bot.com for a list of dealers.
