Why not with volume automation on a submix
On the bus you have an summed audiosignal and fade the volume. You said you'd record the sum instead and apply a fade to the file. Why should it sound different? There is no difference apart from the fact that you cannot apply a curve in the sample editor (which is, in my opinion, a must for a perfect fade).It never sounds as good.
I guess I have the hang of that recording process and I assume, when correctly set-up, it doesn't record the metronome which is not really needed in this instance.OK George but why is it recording a metronome as well as the MIDI files? And the quality so far is not so good?
Resolution? You may bounce in 24 Bit but still lose the 32 Bit floating point on the way. Could be a difference depending on what happens afterwards to the bounced part.Using a bus to combine my final elements in a mix, and then recording the bus as an input, has shown to be better quality than the actual "bounce" function as well. Don't know why.
