So I finally finished the Custom Song I wanted for Rocksmith. However, after following the tutorial in the Sticky section, I was confused. One was, he mentions the use of tone's in the song, and add's some to the song in the Toolkit GUI. I have no idea where he got the tones, why he used them, or how you would even know what tone to use for the Custom song. Another thing I was wondering, if the song had multiple difficulty levels. I am not that great at the guitar, and I want people who are also learning to find it fun to play. If there are other levels you can add, how do you do this? Do you have to do it manually, or does the Editor add in the level's by itself? And a last one. Again near the ending of uploading a CDLC, the tutorial also talked about adding strings or something in the Toolkit GUI. However, I have no string files in order to add to the string pitch list. If anyone can help me with one, or all my questions, it would be great.
