Bounce to track and export issue [SOLVED]

Hi! I'm working on a small project and after exporting it I noticed the piano from Rapture Session had low volume on the mix.
I had some reading on the forum and on Cakewalk site as well (about dithering and rendering bit depth) and I made some tests with the piano track only. I decided to unsolo it before bouncing to track which gave me better results, but still there's loss of volume during the operation.
Is there something else I could do or maybe I'm missing something?
Thanks in advance!
 
Best regards,

Bristol Jonesey, yes. Also it's routed to a 'piano bus' I created.
 
My fear is that other instruments and audio tracks may be be losing volume too, and the piano is the first I've noticed.
 

Hi, Jonesey!
 
I checked my project and the master bus is at -6dB, and I also inserted a VST reverb and a FX Chain from Cakewalk's mastering presets on it.
 
However your post made me check in the console view and I believe I created bus sends [for virtual instruments] but didn't pay attention on what I was doing: the buses out were addressed to 'surround main' (don't know exactly what it is!).
I readdressed them to master bus and now piano sounds lower, but at least it seems to be what was really going on.
 
Thanks for the help!
