I don’t know if anyone else is having similar problems, but I’ve noticed that DP11 v.11.34 has begun to show bugs - possibly due to incompatibility with Sequoia 15.5.
It would take too long to describe DP’s strange new behaviours in detail, but bugs I’ve experienced include:
- MIDI data blocks re-appearing in the Tracks window after that MIDI data has been deleted.
- Recorded MIDI data blocks not appearing in the Tracks window on file opening (even though the MIDI data is there).
- VST2, VST3 & AU plugin APIs not appearing (or functioning) when the 'instantiated' plugin is double-clicked from the Inserts socket, even after those plugins have been updated.
- The counter measure setting not automatically appearing in the step-time MIDI record window (command-9); the previously-used measure reading shows up instead.
- MIDI events not pasting onto single selected Markers in the Event list windows (I think it gets pasted at the counter setting instead).
- Redundant curly stave brackets appearing on single-stave tracks in the QuickScribe editor (they then have to be deleted manually).
- Phrase marks in the QuickScribe editor refusing to hook to the right (selected) end note.
- The Movie window not always updating position when switching from one sequence Chunk to another.
- DP11 crashing (doesn’t happen often, but does so more frequently than it used to).

I’ve updated to the latest versions of MOTU drivers, DP and Mac operating system, cleared caches and re-started etc. Issues persist.
I hope that developers will fix this drop in dependability soon.
