Drifting issue was considerably reduced after V8 firmware on all sensors for me. Also practice of course, trying to keep to the required angles all the time. That song was a while ago so I feel now drifting is almost a non issue for most songs. Maybe towards the end the crash or ride has moved slightly, but workable. I actually did reset once in that video, which wasn’t a big issue as there happened to be a spot in the music to do so (bit like dropping a stick a suppose). And yes, was quite a fast song so there were maybe 1 or 2 crashes when I wasn’t expecting.
I do have elastic bands on the sensors now for even better stability, as I found when playing fast they tended to spin slightly on the stick, which you don’t notice unless you look down and adjust grip.
Maybe another tip is to calibrate the sensors in a natural slight inward direction rather than parallel and straight ahead. Ie get off to a good start.
I think as soon as your angles are slightly off, drifting will start to come in sooner than later.
Also at start try playing through the whole zone, and hear when the drum is at its loudest. That should be the middle. Stick to that angle.
I’m looking forward to 10 zones, rimshot (hopefully in next release) and improved foot action for lifting hats.
