YouTuber Chris Vaisvil took some time to explore microtonal app Droneo. Droneo is one of the oldest music apps on iOS, with an original release back in April 2009. It is still seeing modernization updates to this day!
A bit of a long look at Droneo - a great app for exploring different combinations of pitches. And as I wait for this to upload I am finding more features - a highly recommended app!
