Just replying here on the forum to let other people know we're in touch over email and that we are investigating this with Softube.

Hello, i have an issue , i don't know if it can be corrected, if i have pro Q4 in console 1 => these instance can be viewed in instance list of pro Q4 added directy on cubase track ,but the name of track is not retrieved and sometimes 2 instance of pro Q4 mono related is displayed on the same track in instance liste sometimes it's 2 mono track in instance list. But the problem is that with my cubase template project (no midi , no audio recorded yet) with 20 track loaded with console and pro Q4 in it, each time i go in instance list in a pro4 instance directly on cubase track, it leads to crash cubase. If i replace proQ4 by proQ3 in console1 or if add a pro4 instance on the cubase track (outside console 1) on each track=> no issue, i didn't try with other fabfilter plugin that can be viewed in proQ4 instance list and added in console 1.
