Thank you Tytl
About dynamics and reverb and instruments positions withing the stereo image:
It could well be a science all by itself, but there is some logic even we, who judge only by ear can put into place.
First : The reverb I added on the last version is a stereo studio reverb, put on to a pair of 20% panned mono channels. (80% dry signal against 35% reverb)
I think that if we would meassure the spread of the channels (20% off center to either side) we would see the reverb widening the original stereo channel, by traveling to the 100% panned position on both sides ( actually the speakers positions)
That, I think will pull the lead track more together with the backing.
Due to the fact that reverb trails after the original sound and sounds wider, I guess that will even out a portion of the volume changes on the next tone or tones.
Actually I think it's the silence between the notes that accentuate the playing /volume dynamics
Try for yourself, record two dry guitar notes and look at the volume view in your daw, now add reverb to the note either by playing with reverb or adding it in your daw. (copy the output result to another channel)
Noow look at the signals and you'll notice the gaps between the notes are filled with reverb signal, resulting in a more filled up track.
So concluding it just may be not a case of actually compressing the guitar notes sound, but more the filling of the gaps between the notes with sound/reverb.
Mhh not my best post, but I hope it paints the picture clear enough
