song after render sound totally different the execution in reaper

I mean, I recorded 4 tracks, 1 drums(addictive drums) and 3 guitars(Guitar Rig), well, I hear one thing in reaper, and its good, but after I render the project and I go hear in media player, the volume change, the instruments sounds different, kind more bass. But if I open the song that I recorded, in reaper, it sounds fine, just like sound in project before render. What im doing wrong? Thanks!

What file format are you rendering too? Mp3? Wav? Flac? Whatever format you pick, try selecting the best audio quality as an experiment. Also, try at least one rendering to highest quality WAV format to start with. The file size will be big but you can delete it after listening to it. I would start with a wav render first to rule out Mixer settings (whether stuff is sent to Parent folders AND the Main out, etc) if it sounds the same, then it is probably the quality and format you are rendering too. It is hard to say without seeing how your project is set up but rendering to WAV first will rule alot of stuff out if the result sounds like you expect. Good Luck!

I just fix it :D Thank you I had setted my default sound reprodutor, to play in 192000, and I was recording in 44000, so I just changed my reprodutor to 44000 and sounds like perfect! Thanks for your quick answer!
