Hi thanks for the prompt reply.
Tried again tonight in a bit more structured fashion.
I exported the midi file from bs16i as a wav file and imported into cubasis to marry with the same midi file already imported as a new project. This matches. I also did a mixdown of the midi tracks only within cubasis and reimported into cubasis again this matches. So far so good.
Tempo appears to be stable tonight but this may have something to do with me using virtual midi to drive some external synths before -I will look at that a bit more.
The first obvious thing is the drums to not map to GM standard. Is this planned? Using studio kit btw. This may be part of making it appear the tempo is wayward?
The midi file is http://www.free-midi.org/song/pet_shop_boys-west_end_girls.html
Thanks for now.
