This is not appropriate at all.

Blow a trumpet, a sax or a flute, and without ceasing blowing change the note or even do a trill. The effect is completely different from a non-legato (there are multiple kinds of that) e.g. by stopping blowing, change the note and the do a new blowing attack.

Move the bow of a violin and press a finger on the string. The effect is completely different from a non-legato done by stopping the bow, changing pressing the finger and then start the bow moving - usually in the opposite direction.

And as you see: no pitch-bend sliding involved here. But decent solo sound engines of course are able to do legato transitions that include pitch bending. This is controlled e.g. by the velocity of the target key's Note-On message.

In fact decently crafted solo instruments (like AudioModelling's SWAM based Flute or Cello or SampleModeling's Kontakt based "Trumpet" are all about doing perfect transitions between notes. They distinguish between multiple modes from staccato to legato. Here even the Note-On velocity of the target key is used to do a more or a less harsh transition. It's an absolute no-go not to support this by the keyboard.

The ROLI should be used to play several different kinds of sound engines as different "patches":
- its own 15 voice MPE aware synthesizer
- one monophonic voice such as SWAM Flute
- one dupohonic engine such as SWAM Cello
- standard polyphonic (not multitimbral) sound engines such as Kontakt sample instruments or physical modeling Hammond organ plugins
- sets of multiple (say five) monophonic engines (e.g. SWAM or Kontakt based) to do sets of Orchestra-like sounds.

The patch switching needs to be done by means of a Midi message from a controller board. (No PC GUI available when Live playing.)

Now the MPE signal from the ROLI śeems to need to be preprocessed and distributed to the multiple instruments in different ways according to the actually selected patch. Or is there a way to send the ROLI a Midi signal to have it switch modes (e.g. between "Mono" or "single channel" to allow as well for normal Legato performance as for playing standard polyphonic instruments, and MPE for dedicated instruments such as the ROLY MPE synth and dedicatedly crafted sets of monophonic "orchestra" voices.
