Matteo described the technique as a "rest stroke" technique, much like how bassists use their overhand fingerstyle. However, his 2nd technique (which I'd need to review) was described as a curled hand "classical" picking style. The combination of the two, (plus some darned decent outside-the-box chops) makes for a enjoyable listen.
We had Matteo at g66 boot in Padua Guitar Show last year and he tried (and enjoyed) the FM9. Here's a clip of his test with the great @Marco Fanton
