... circling back here, @theneweuropa, thanks for your reply and info above!
All considered, I think I'll grab a Stolperbeats in the next few months when possible. I like it potentials for altering the "time grid" holistically with a few controls, vs. needing to edit microtiming by step. I think this potential is interesting not only for drum programming, but for setting a groove which can also be fed to other ensemble instruments.
