Yes, .. and no
The LB 302 has a flag to set glide on.
All Plugins have a pitch-correction, but it has not a wide range.
When you want to slide with the 3xOSC you can automize the basepoint (note) by dragging it into an automation track. But this isn't a really sliding, it is just a 'walking' though the notes.
I think sliding is a part of the plugin you're using. Try an LFO on the pitch of the synth (VSTI?). So you have less artefacts, too.
