that’s right, it’s definitely harder to produce circular breathing on the Vib. than on other melodicas, and I’m still practicing a lot without getting a really satisfying result.
The two videos of Alan seem to show two different ways to produce a circular breathing. The Didge guy breathes in and out giving both parts the same length, whereas the flute girl breathes out long and then breathes in short and sharply (you can really hear her breathing). Perhaps it would be good to breathe flute-style for all instruments that lose air quickly , which certainly includes the Vib. I’ll try out and report.
