Hi Kim
I just bounce the vsti’s to audio. I don’t use many though, mostly Addictive Drums. Sometimes down to a single stereo file and sometimes to individual files. I do this for backup purposes as well as mixing. Of course this does mean a larger file to upload for sharing. That is why I chose this short and fairly simple song to share. For this little experiment I batch exported all tracks to 24bit but I think 16bit files would have been ok for this purpose.
Cheers
