It’s working out pretty well for me using BFD3’s stereo 64-velocity layer acoustic kits. Here’s my layout:
Blue = kick; red = snare hit, drag, and rim (plus a few isolated cymbal chokes); cyan = ride and bell; magenta = toms; green = crash and cymbal; orange and yellow = small percussion 3-4 articulations each (bongos, djembe, timbales, high pitched tympani); white and clear = various hi hat articulations. Some of the colors you can’t tell apart in the photo.
I double up on many things diagonally to play rolls because it’s difficult to trill two fingers on one of those small LinnStrument keys. I group 4 for a cymbal crash so that I can palm it. I reserved the bottom row for LinnStrument functions, so the stuff I’ve put there isn’t strictly necessary, though it’s nice to be able to lay a thumb flat against those three blues to play a loud kick without ever missing. And I’ve still got 7 empty columns (49 keys) leftover.
My layout is symmetrical to play with left and right hand at the same time. It’s one-handable, but for more intricate playing, I dedicate one hand to bass/snare and the other to hi hat and ride, then different mixes of the rest–that’s just the approach to fingerdrumming I’ve developed from years on Zendrum controllers. In fact, if I can make this substitute for the Zendrum, that would free up space and funds because the triggers-only Zendrum can only do one single thing even if it’s the best at it. I have to say at this point that I think with a few weeks’ work, I can get this LinnStrument drum controller up to the level of my Zendrumming. I think, though, that standing with the thing strapped on guitar style will be too hard to control compared to the Zendrum because it’s just plain harder to see what you’re doing, and you can’t play strictly by feel as you can with a Zendrum because the LinnStrument has so many little targets. I’m also concerned that its lighter weight will make it move around much more than a Zendrum. These things will makie it impossible to stand and still hold down drumming duties reliably. It’s amazing what you can get used to with practice, though, and I rarely play standing anyway because I don’t like the weight for ergonomic reasons. It’s very possible, then, that my beloved Zendrums will get liquidated in the next few months.
