Issue: Multiple instances of articulation in expression maps on single note

[Muso_Chris]

There is a bug where if you trigger an attribute articulation via a remote switch or selecting it in the left while recording live midi performance, that articulation can get added twice. The articulation in question is a 2nd group attribute that I created called “shortest” (custom articulation) this was originally a direction then I changed it to attribute.

I’ll supply the expression map here: 119.2 KB file on MEGA .

Steps to reproduce are:

1. Use an expression map with a sound slot that requires 2 articulations, one in group 1, and the other in group 2. For example, the sound slot in that expression map that I have called “Spiccato or Note Reps”, but other’s might set something like “sustain con sordino”.
2. Hit record, then press the relevant remote trigger for that sound slot, then play in some notes. On my side I then get this on the resulting midi:

Note: “Shortest Shortest” is on the midi note, but it is not duplicated down the bottom. When switching the group 2 articulation to something else, like medium, the shortest attribute is still there:

And I can confirm the above does not change the sound slot as it’s supposed to because of that lingering “Shortest” articulation.

*Another way to reproduce (what appears to be) the same bug, where multiple copies of articulation exist on a note:
*

1. Make a lot of notes in a row. Like about 16 semiquavers.

2. Select them all

3. Pencil an articulation in the controller area/zone

4. zoom in, staccato is created once, awesome, but…

5. switch that articulation to something else, by way of selecting all the notes again, then clicking on the articulation’s arrow and picking something like pizzicato, and then we have:

Hope that makes sense. Let me know if you need further clarification. Also I apologise if this has been reported already, I just wasn’t able to find it. Thanks for your time!

p.s. cubase version is 15.0.10

I was able to reproduce this. It looks like a bug.

Per my observations, the duplicated articulation issue happens when:

• Using a collapsed articulation group lane, while having selected multiple notes at once.
• Using attribute articulations.

It appears that the # of duplicates is equivalent to the # of notes selected. To clarify for other folks, the duplicated articulations can be seen next to the note name, not in the lanes.

In the meantime, here are some workaround ideas:

• Workaround A → Use the expanded group lanes inside each group.
• Workaround B → Use the Articulation dropdown in the Info Line.
• Workaround C → Continue using the collapsed group lanes, but selecting only 1 note at a time.

Hope this helps!

I can also confirm. I think this is just the text that is duplicated, no?

Also affects the entries inside the group lane, where only one articulation is supposed to be set at a time.

And I can confirm the above does not change the sound slot as it’s supposed to because of that lingering “Shortest” articulation.

Chris mentioned it’s causing some sound slots to linger. I have not been able to reproduce this. Certainly needs more investigation.

So this confirms that it’s not just text. Interesting that the drop down shows multiple there, this seems to break the mutual exclusion rule.

I guess with ”Lingering” … what’s actually happening is that when a bunch of more than one articulation from one group exist on one note, Cubase picks the last articulation attached to the note to prioritise in the logic, even if that last existing articulation in the bunch is not visible in the collapsed group lane. Then, when trying to change that articulation in the drop down to something different, it won’t change the last one, but one higher up in the bunch instead, therefore we get an unchanged sound slot because of lingering additional articulations on the note.

Ultimately mutual exclusion can break using the above means. Hoping Steinberg will have a look at this!
