Doctor Drone 4+

Innovative Practice Tools brings you Dr. Drone, a simple, affordable and powerful practice tool. Dr. Drone gives you the freedom to create your own bass lines, chord sequences and drone tracks and set them to a metronome. It opens whole new avenues of practicing for professionals, pedagogues, ensembles and students. It will become your favorite tool for developing great intonation and stability.

- Want to prep for a specific piece? Enter a bass line to your favorite tune, or enter a melody using either note names, scale degrees or solfege syllables in an intuitive entry pad.
- Need more time to lock in each pitch? Vary the tempo between 40 and 500 BPM (because why not?), set each drone from 1 to 60 seconds, or select "Tap to Advance" Mode to tune along at your own pace. Heads up: "Tap to Advance" is compatible with your favorite Bluetooth pedal, or anything that can send arrow or enter key signals to your device!
- Trying to expand your range and stability? Dr. Drone will repeat sequences and can transpose them in a number of patterns (transpose the sequence around the Circle of 4ths, move up chromatically, etc.)
- Want to practice tuning within a chord? Add a Perfect 5th, Major 3rd or Minor 3rd to your drone (using just intonation) to practice fitting your sound right into the harmony.
- Want to tune to custom chords? Create your own voicings with up to 10 pitches in "Chord Entry" mode.
- Toggle between Just Temperament and Equal Temperament.
- Got some 'go-to' exercises or warm-ups? Save and organize your tunes along with their settings for repeated use.
- Need to practice for your next orchestra gig that requires A443, or your next baroque service that calls for A420? Easily adjust your Concert Pitch A to be ready for any intonation situation.
- And if you really want a challenge, Dr. Drone includes a feature that allows you to randomly silence beats for the ultimate test of time and pitch independence.

From classical to jazz and from pop to gospel, this app is perfect for serious musicians and music educators who want to have a steady and flexible reference drone. Its sleek design, friendly features, and video tutorials will have you using it like a pro in no time. Welcome to the 21st century of intonation practice with Dr. Drone!
