Crash when rendering step clipto midi clip.

[mikoatkvr]

Hi I was working on a project for a couple of hours and completely lost it after the crash ( it may have been my mistake by choosing 'open original' as I was worried opening the temp file might not have survived the crash ).
The crash occurred after a lot of editing, copying etc of a step track with the multi-sampler and in the last section i chose ( think it was 1 bar long or so ) I tried to render the selected clip to midi.
I have not been able to reproduce this again yet , but I checked the log file and thought this bit might be useful :-

Other vst's used were #TEqualiser , #TReverber8 , #TDucker #TCompressor << [ used in a rack with multi-sampler]

Perhaps I haven't enough debug info as to make a useful bug report and recreating this crash might not be easy as the particular project had a lot of tracks rendered , timestretched , re-rendered etc then eventually deleted, perhaps some random chain of events lead to this.

I will keep an eye on this crash and perhaps I will be able to reproduce it in the future, in the mean time I thought it was worth reporting . thanks
