No. Only one slot can be transmitted at any one time. Groups are assigned to… slots (with up to four groups on the slot). And the Groups are totally meaningless apart from in the Score Editor (like I wrote earlier, if the articulations from those groups are present concurrently, then if that combination is recognized as belonging to a particular slot, then the slot will be transmitted).
Let’s try a not-too-complex concrete example…
Let’s use a string instrument, and have two articulations (plus the basic “arco” in slot #1)… Pizz, in slot #2, and sordino in slot #3.
This does of course assume that the receiving instrument (let’s presume a sampler, such as HALion or Kontakt) has three patches… arco, pizz, and sordino (which will, presumably, be played arco, but with the mute applied). The only way to hear pizz played sordino is if there is a fourth patch, which contains that particular sound.
So, for the time being, let’s just have the three slots, with the appropriate articulation loaded into each.
Write an “arco” into the score… Cubase will recognize that there is a slot which contains that articulation, and therefore transmit the data that is written in the top-right section for that slot.
Similarly for the other two articulations.
And it doesn’t matter which Group you assigned the articulation… if there is only one group present in the slot anyways . But, for the sake of simplifying what follows, lets put each articulation in to its own group (arco in group 1, pizz in group 2 and sordino in group 3)
So, at the moment, if you had started the score with pizz (which is on slot #2), and (without later changing it to arco (slot #1) ) you now write “sordino” (slot #3), it will simply play the patch that is sordino (i.e. still arco, because that’s what the samples for that patch are).
If you want to trigger the patch that contains the pizz played sordino (that fourth patch I mentioned), you have to write a fourth slot (where the top-right section selects that patch), and put the pizz articulation into group #2 of that slot, and the sordino articulation into group #3 of that same slot (don’t forget, you fixed the group numbers when you created each articulation, in the bottom-right section)…
Now, if you write the same as above, with pizz at the start, and later add the “sordino” articulation, Cubase will recognize that “pizz” and “sordino” are concurrent, and exist in a valid slot (slot #4), and now transmit that slot, which will now play the fourth patch (samples of pizz played sordino).
