What's New in Doctor Drone

2.52

February 22, 2022

- Added "solfege mode". Functions the same as "scale degree mode", but... uses solfege syllables! Aural Skills students rejoice! - Bug Fix: When repeating using a transposing pattern, the selected octave "range" is adhered to again!

Organization

Great app. Only thing it needs is more features.

It would be great to be able to highlight and loop sections or have markers that we can regularly start from in each file. That way if there's a specific spot that needs fixing we don't have to play the entire section or make a new section for that one spot.

I would love to see an option for a Pythagorean tuning option as well as being able to choose the key center. I'm not sure how accurate the just tuning is at the moment as the notes are tuned to the bass note instead of the key.

Better organizational features would be great. At the very least we should be able to have our presets saved in alphabetical order instead of a random order as it is now. The best option would be to let us drag presets around.

It would also be nice to be able to have a bigger variety of note values although I understand this will take time.

Volume

I just got the app this morning. I think it is going to be a great tool. It would be very useful to have a volume control to allow balancing level when using in combination with another app. It is too limiting to have to only use the volume control on the phone. Thanks

Really useful and easy to use

Great app!

This is practical and useful for ear training and singing exercises.

Is it possible to provide movable solfege labels both ascending and descending.

Thanks

Update Dec 2024.
Still a great app. Really useful to practice voice exercises, scales intervals across all keys.

Two items for wish list:
1. Can change flats to sharps - enharmonic. Example d major shows Gb instead of F#

2. A list of scales with octave short to start at any point on keyboard. Would like to hear and practice different keys.

Otherwise, still a fantastic app that I really like. One of the best I have purchased.

This is

Great for learning to hear and play in tune. It would be better, if I can change the length of the notes and chords on any given setup.
