Nuendo 15.0.30 - Bug Collection Thread - June 2026 | OPEN for posting

Tested and confirmed in Nuendo 15/Cubase 15

Video Proof: Modulator assignments disappear from projects?! - Cubase - Steinberg Forums

Modulator patch assignments intermittently disappear from projects when:

  • There are multiple patch assignments (when they disappear, only one is left)

  • Opening or Activating a project (best way to test this bug, open two duplicated projects and activate back and forth until you see assignments dissappear)

  • Also maybe related:

    • Track Presets don’t restore modulators/assignments
    • Import Tracks From Project, doesn’t restore modulators/assignments
    • Import Track Archive, doesn’t work
    • Duplicating track, doesn’t work
    • Modulator renames don’t save with project.
      • Ie, Modulator protocol integration is either completely bugged, or was never integrated to begin with.
  • (best way to test this bug, open two duplicated saved projects and activate back and forth between them until you see assignments disappear)

This is finally confirmed by another user:
