direct offline processing & external FX

Have problem with it.

when i apply External FX (compressor) to an audio clip, Cubase just closed. no warning messages or .dmp, nothing.
UR44 -
External FX Send is 3/4 (left) Mono - unbalanced
External FX Return 5/6 (left) Mono - unbalanced

Or DOP shouldn’t work at this way ?
thanks!

Hi,

Make sure DMP file has not been created. Double check this in the Documents/Steinberg/Crash Dumps folder, please.

If no DMP has been created, make one by using Microsoft ProcDump file, please.
