Hi!
I'm still new to recording, so it might only be a wrong setting, but: when I record something, its loud, and good.(using th3 amp sim) When I record another track (using th3) the second track's volume is waaaay lower, altought I use the same amp settings. Surprisingly, when i play the two tracks together, they are both as quiet as the second track. I hop you can understand, what I am saying.
