Hello,
Same here: 2 Beatsteps (one black, one white).
Would be good if they'd both could be addressed in MCC at the same time.
No idea if it requires some device-ID to be set at the controller itself (which would require a firmware change), or that an MCC-update would be sufficient.
(I know, I could switch to a BeatstepPro, instead of multiple Beatsteps, but still, there's always a valid reason for multiple devices of the same type...)
