This is such a coincidence 'cos i just learned the scale (starting on a different degree) in all keys.
I learned the structure of it from a post by Musallio, but i varied my application of it.
the way i play the same scale u posted, i start on the C:
C,Db,E,F,G,Ab,Bb,C - - - - i can use it when playing in Eb,Ab,Bb,C and im sure many more that i have yet to discover.
What's even more interesting about this scale is that if you treat it as a normal major scale, you can come up with some beautiful progressions.
Again the formula: 1,b2,3,4,5,b6,b7,1
