Hi, I’m wondering if anyone else is experiencing crashes due to expression maps. Here are the details:

- Crash happens when two keyswitches are overlapped. For example, if I hit C-2 and then hit D-2 without having let go of C-2 it will crash.
- It happens randomly. Sometimes it will be from D-2 to E-2, sometimes it will be other keys.
- Crash happens using any expression map, not just a specific one.
- It will crash on any template, any project and on the default empty Cubase project.
- Usually takes about 4-6 keyswitch changes for it to crash.

I’ve attached some of my expression maps if you guys would like to see. Anyone else experiencing this?
