I’ve made a Morph map for playing percussion using BFD. It’s got about 45 areas, with a lot of redundancy so that it’s mostly symmetric between left and right hand. Zendrum, by comparison, maxes out at 30 triggers, and 25 on the more compact model that I prefer. I simply put the Morph on top of a wooden cutting board, and it can be fingerdrummed on my lap no problem. Like a LinnStrument, if you played it standing, you could only use one hand, and you’d have to use maybe 20-25 larger areas. But you’d have to come up with some kind of clever design to play this thing standing up. I wonder how well it works with Bluetooth. Latency would have to be under 20ms for percussion.
One drawback is that I can’t get this Morph to send out a MIDI velocity below 30. Even the lightest touch only gives about 33, though I think I once saw 27. I’d have to run it through the DAW and use a velocity mapper, which is exactly what I want to get away from. It has a pretty good feel with its stock maximum sensitivity setting across the range that it does reproduce.
I got a bunch of tiny stickers that I can use to indicate landmarks on my map. Playing while looking at the map helps develop muscle memory, and with 20 areas under each hand in a symmetrical layout (with 4 running down the center), it’s not too difficult. Maxing out the areas to a 7x13 grid would have been really difficult, but there’s no reason to have such a fine grid. I have repeat notes on the LinnStrument next to each other for playing stroke rolls (trills), but of course on the Morph, you accomplish the same thing by creating a larger area. Now I’ll see over time if I can really play it as well as a Zendrum.
EDIT: I see from Sensel’s forum that the Morph’s minimum velocity is way too high by design, around 32. It’s a real problem, and I wonder why they designed in such a shortcoming; I don’t think it was an accident. My LinnStrument designed in a minimum velocity in the low 20’s, I’m told by Roger Linn, after user research. He also told me that velocities below 20 are excluded from usefulness in normally compliant plugins, so they won’t change the sensitivity. But Sensel’s minimum of 32 is too high.
