Impossible to record midi in comping mode. Sonar crashes!
Last upgrade of platinum 64 bit with tc electronic konnekt48 asio drivers. The was not any problem until now...

Might be the same problem I was having (mentioned in another thread, it doesn't seem very widespread).  Do you have the take lanes view open in the track you're recording?  If so, try setting Take Lanes = Off for the track, and see if it still crashes when you record in comping mode.

Thank you. I will try this, even if I think that is an issue to be fixed.
