Hi Jim

Coming to this one first.

First thing BIAB says when you hit 'Choose' for a file save location is 'Choose a file name. The file chosen must reside in the same folder C:\BB\ ... I tried that advice - still got the blank render.

Following your method. No 'make separate files' button - un-ticked 'Merge in Audio track' - same thing?? Do the (re)Render to WAV thing. first thing it tells me is 'REMEMBER UNLESS YOU HAVE MIDI SET TO RECORD IN THE RECORDING PROPERTIES NOTHING GETS RECORDED' - but as I posted earlier, 'Set Recording Properties' button does nothing (?!?)

Later, in the desktop folder I find a track called Render_1 which is very short and silent.

The Render dialogue box meanwhile tells me I have saved as BB\_NONAM~1.WAV. Never heard of it - must be a default name, That's 8 secs long as well and empty too.

Any ideas?

Thanks again

Robert
