it is not specifically a MG problem, but more a general one:
Synths can not legato connect bend notes: there is only 1 general bend per channel.
If the note is bend up, it can not be connected to the next note, since that higher note also is ruled by the same bend parameter: the frequencies can not connect.
Circumventing that is rather complicated, it is on my todo, but uncertain how well it is patchable.
