I saw this video while I was at work a few days ago and I thought it was tremendous and worth sharing.
While Robbie is using it in a modern jazz based context, I could see this making for some incredibly interesting sounds in a more metal or prog context - the note sequences remind me of Tosin Abasi’s selective picking and thumping.
Cool idea. Allan Holdsworth uses it at the end of his solo on In the Dead of Night (so likely other places, too).
I personally discovered false fingerings on my own when I was practicing some time ago;
I do love the sound of it and I use many of my own patterns with false fingerings to practice my dexterity (stretching fingers), but I have never managed to make it sound actually good in any of my songs.
