Linux 64 bit, rc1.
Steps to reproduce (download the attached song):
- Highlight all the lines in one of the blue patterns
- Render to sample
- new rendered sample gets placed on to the source instrument so, in this case, you end up with a VST instrument and a rendered sample in one instrument.
When it happens is quite inconsistent, sometimes it creates a new instrument as it should do and sometimes it doesn't. I've only managed to reproduce it from rendering all the lines in a pattern so far (as opposed to just 16 lines).
