Thanks for the reply. I'm not sure what version I have, but in the other CDLCs that I made, everything works fine. They are mostly in E standard or Drop D. So I don't think that I use outdated versions, but I will check for newer ones. I think the error is in the downtuned songs. About the strings, I can easily play B Standard songs on my solo guitar, the game registers all the notes. But in my CDLC, the game barely registers anything. As for the bass, you are probably right about the thicker strings. I didn't check the tuning in EoF, but I imported a 7 string guitar tab so maybe it did f*ck up the things. But I have an idea. If you have time, please check my CDLC, and tell me what you experienced. If you play the Drop G# song on your bass, and the game registers the notes, then the problem is my strings. But if you experience the same errors, then the problem is with the CDLC. But I don't think that I did anything wrong, I created those songs just like my other CDLCs, and those are works fine. http://www.mediafire.com/download/kvf58uhzvyycdfd/Leander-Rising_Nyolcadik-Fobun_v1_p.psarc
