Well, I've set everything up exactly like your video shows, changed back all the pads to ch. 1 in the Controller Editor and I still get only 1 sound at a time. Clearly, I'm still missing something.
Maschine must still be in Midi mode correct? Also, when I set the Group Input to ch. 1, if I make it active, I hear no sounds at all...
Feel free to answer at your leisure. I will continue to work through this. I really do appreciate all the help.
