"thin data" crash and

Cubase
1

I’m in an old project, and try to “thin data” on my midi CC… initially it gave a popup and crashed cubase, but now it simply won’t thin the data on existing tracks.

When I create a new midi track, it will thin the new CC just fine.

Tried (on the old tracks), but didn’t help:

  • exporting/importing midi tracks
  • did a “backup” of the project and tried there.
  • copied old CC data into new track
  • switch all CC to/from step/ramp

Update.

My track has a LOT of CC (volume) data. When I delete most of it, and try to “thin” just the first bar’s worth of CC, it thins it ok.

Strangely, I created a new track, added a lot of CC data, and tried thinning and it thinned the whole track just fine.

Basically, I need to de-corrupt the original tracks somehow.

(also odd, seems when I select a small section of cc data, sometimes it thins only that section, sometimes the whole track..)

attached is the crash dump

Cubase 13.0.55 64bit2026.7.10 11.27.02.710.dmp (1.5 MB)

Solution.

For some reason, an extremely low tempo data (the piece slows to a almost halt) messes with “thin data”. Changed it to bpm 10 or so, and all is ok.

FWIW, the dump file shows this from Cubase:

INTEGER_DIVIDE_BY_ZERO_c0000094_Cubase13.exe!Unknown

PROCESS_NAME:  Cubase13.exe

ERROR_CODE: (NTSTATUS) 0xc0000094 - {EXCEPTION}  Integer division by zero.
