I am running a PC Lenovo G50 with Windows 8.1, whatever the latest version of Studio One 3 Artist we are on to date: just did another update today 5/23/2017. Now, when I am running two guitar tracks (one rhythm and one lead) it is like I am just stacking my virtual amp models on top of one another and the initial track sounds great but when adding the second or third guitar track to my 2 input USB Audiobox it goes into a terrible amount of distortion and it sounds so horrible like a bad AM radio station. To further explain this when I then move on to drums and record live drums with two mics and add say reverb or a drum preset in Studio One 3 the effect then gets added onto the guitar track and so on and so on. I understand I technically I only have two inputs but is the only way to record multiple guitar tracks is to record them directly from my amp? I can, but it is so much easier in the initial demo phase of writing a song to simply use guitar presets and lay down my basic guitar tracks. Then track my drums, bass, then real guitar, and vocals. I have tried to set up additional inputs but that obviously does not work since I only have two (I thought I could trick it into adding more- yeah right!).
