Hm another way could be this one.
You duplicate a whole scene (it's the same procedure like duplicating a pattern but in the scene menu). Then you duplicate the one pattern you want to edit, edit and replace it.
And to the MPC/Maschine thing. I think there are some major differences.
In MPC you have 8 Groups and every group can carry 16 sounds.
And then you do sequences with all sounds of all groups and you arrange the sequences in the song mode.
The difference is, that the patterns (similar to the sequences of the mpc) are bound to the groups.
You have also 8 groups and for every group you have 64 patterns and you arrange them in the scene menu and you can place in one scene one pattern of one group. so, if you want to place Group A - Pattern 1 and Group A - Pattern 2 in Scene 1, I think that doesn't work. You have to copy the whole group to another one.
I hope that's right, if not, please tell me
I think that's something important to know before you start your song to structure and arrange the sounds to the groups you need it.
I do it this way:
Group A - Drums, Snares, Hihats
Group B - long Samples, sliced Samples and soon hopefully timestretched Samples
Group C - Percussions, Bongos and stuff like this
Group D - Bass if needed
And I think you could say:
MPC Sequence = Maschine Pattern
MPC Song = Maschine Scene
MPC Group = Maschine Group but they work different
EDIT: And again to the duplicating thing.
You can of course use the duplicate button. You go to the Scene of Pattern Menu on your controller, press and hold the duplicate button, select the pattern/scene you want to duplicate and select an empty scene/pattern where you want to have it.
AND you can of course do the same wit a group. Just use the duplicate pattern and duplicate the whole group and edit the patterns.
