Hi. I just got a MD SPS-1 MK1 I wonder how I should do to get the inputs to work? I wanna use a TB-3 and a trough the MD but I 
nothing.
It’s been years since I let my Machinedrum go but as far as I can remember you have to trigger the machine before you can hear the input. It’s not enough to just select it.
Also, if I remember correctly, after you trigger it, it remains active if you choose a midi machine on the same slot so you have a free input.
