I hope it’s not the case the case that Embodme has had to set a fixed “optimized” velocity response due to other competing performance factors.* The present response is OK, but for drumming—whether fingers or sticks—velocity sensitivity is the one. In that case if having the option to neglect pressure, X, and Y somehow makes a velocity curve more doable for a drumming-centered patch, then that would work. I’ve been drumming with BFD3 and a TD-50, and it’s really very good as is, but it would be nice to be able to customize the response.
*ADDED: I just noticed from your other post:
I was afraid of this, but the Erae is within my tolerance. I do get relatively dead spots, though, and I can’t make heads or tails out of that calibration technique where you rub the surface. Maybe it would help, but maybe it won’t accomplish anything more than the power on calibration.
