macOS: NI Massive AU - Audio glitch/clipping when tweaking parameters

OS: MACOS Tahoe 26.1 Arm64
Renoise: 3.5.4 clean install

tweaking parameters in AU version of NI Massive (non X version) causes audio glitch/noise-burst/clipping in Renoise 3.5.4. This doesn’t happen with the VST version though. To my ears if feels like the buffer becomes corrupted.

Update: this doesn’t happen in Ableton.
