Didn't think of being in Monophonic for that but yes, it works! Of note: this particular use of Glide is the only one I don't see mentioned in the manual (again, Icarus 2, might have been fixed since).
That leaves me with one case I can't reproduce : glides that happen with notes touching each other (one ends, another one begins at the same time -- no gap), but without needing overlap.
I have some VSTs that have legato work like this but I don't have enough experience to know if this is to be expected, or just an implementation choice of legato.
