I use Maschine+ exclusively in standalone mode. I have a song comprised of three verses, each of which I've set up as it's own scene. The song has a string part which, in the first verse is a single line of notes, and then in the second verse I add another line of notes on top of that, and in the third verse I add another line on top of that (such that the third verse of the song has three lines of notes comprising something akin to triads as I move through the chords of the verse).
Right now, I have this implemented as three different patterns (verse 1, verse 2, verse 3) within my group called Strings. However, that means there is a copy of the first line of notes in the second and third patterns, and a copy of the second line of notes in the third pattern. The problem with that is, if I want to change the notes in the first line, I have to change it in three places, likewise changing the second line of notes requires making changes in two places.
Another way I thought of doing this is to have three groups - String Line 1, String Line 2, and String Line 3 - that I call up progressively using the scenes in Song Mode. But then I wouldn't get to see all three lines of notes together in the pattern view for the third verse (or both lines of notes for the second verse) which helps me in composing.
What is the most efficient technique for layering on additional MIDI events as you progress through scenes in a song?
