Covert MIDI to audio

Just an update.
 
When I tried to re open the session after saving the audio is not recognised and has therefore not saved.

That was a great help.
 
I did find under help about converting midi to audio on cakewalks site and tried what they said but it did not work. After I assigned the inputs and outputs correctly a signal would show up on the midi and audio tracks but there was no red arm button.
 
But bouncing has worked so I shall do it this way from now on.
 
This forum is a blessing as I probably would still be trying to figure out how concert midi to audio.
 
I do think its funny that somethings seem quite hard to figure out for new users when I think DAWS could have simpler ways of doing things.  Like there could just be a button that says "convert to audio" and its done.  Surely thats possible?
 
It is fun trying to figure things out but I have read numorous threads where people get stuck after seeming to try everything and then only find the answer out form asking people like yourself.
 
Thanks for the help.
