Theoretically, one could simulate slide with MIDI by carefully inserting a pitch bend between notes, but it would require some kind of calibration feature to match the synths pitch bend and tuning. Its too complicated to set up, so as far as I know nobody has ever implemented it in a MIDI device. I would love to hear if it has been!
It might be possible to get a synth's Glide to sound like a slide, but The NDLR motifs are strictly monophonic. Its not something a typical mono synth MIDI implementation would handle as far as I know. And a polysynth would just play both notes unless its configured for a unison mode. Assuming the synth will glide on overlapping notes, it would still take some futsing with the glide time to get it to work with the selected BPM and clock div.
True, nothing in the MIDI spec specifically supports, or mentions, slides. But, many monosynths do implement an auto-glide based on how data is received. For example, my MAM FB-383 will make a slide if the second note's Note On comes before the first note's Note Off is issued. Since the NDLR's Note On follows a Note Off with only about a millisecond between them, the suggestion of swapping Note On/Note Off in time would make many monosynths do an auto-slide.
One possible implementation would be to have in the Rhythm Editor a scenario like this:
Note 1 Vel 120
Note 2 Vel 110
Note 3 Slide
Note 4 Vel 121
This would be played as:
Note 1 On Vel 120
Appropriate wait
Note 1 Off
Note 2 On Vel 110
Appropriate wait
Note 3 On Vel 110 *
Note 2 Off
Appropriate wait
Note 3 Off
Note 4 On Vel 121
Appropriate wait
Note 4 Off
*Note 3 On velocity is unimportant as the EG is still triggered from Note 2 at this time and is sounded in the decay of Note 2.
