I wonder how Push will handle accidentals (other than the diatonic pattern); for example, Flamneco uses the relative major (C) and the harmonic minor (Am), in the same context as the E Phryian (in this case, the "tonic/final" is an E major chord (requiring a G#), whereas G natural is used in the standard "Andalusian Cadence"" Am -> G -> F -> E(7) (i.e., the E7 is the dominant chord for A harmonic minor).
From what I see, Push's "chord shapes" are all G7 or Am7, which might be ok for jazz, but not for real musicans, who want to know.....
