pitch bend isnt smooth its notey

hi i just bought a voyager rme and when i do a slow pitch bend it doesnt sound like a smooth glide between notes it sounds notey or intervals of notes. is this a setting or is there something wrong with the rack. i have a signature edition and it doesnt sound like that when i do a slow pitch bend.

You may have the resolution in the RME set to ignore LSB to decrease the MIDI stream or your controller may not have the resolution needed.
