Sculpture Legato Bug

Mainstage 3.2.4

When using Sculpture in legato note mode, the synth stops responding to MIDI notes at a certain pitch above the initial note. It responds to all notes below this limit though, so it's not "stuck". When using my EWI4000s as the MIDI controller, the limit seems to be 5 semitones above the initial note. Using Musical Typing, the limit is about an octave above the initial note. I tried multiple preset patches, and they all exhibit the same problem, with the same upper note limits when in legato note mode.
