hey:) about 1 ye,since rocksmith only have lead and rhythm guitars there are only 2 "real guitar" any other guitar you can only add as bonus(you can decide as bonus lead or rhythm tho) as mentioned you can use bass track or what i do is use the same tracks of lead/rhythm but when you have to save use 'save as' and put it in a sub folder so you dont overwrite your main tracks. Making lyrics for japanese music is really time consuming i did it on my 1st customs but then i got lazy + ppl dont really care coz they intrested more in the guitar/bass parts:) anyway im not sure about other ways than ultra star but that program really does very little of the job if you are looking for the perfect lyrics somthing like this took me 3-4 hours probably as you can see on the video the way i did the english words is 1 way of doing it but on the jap words i did extra work and they became blue every syllable. so cutting words in the right place and keeping them blue to be same as vocals is alot of time,ultrastar wont make your lyrics blue and wont cut your words aswell- that has to be done in EOF. if you dont know wtf im talking about check this :)http://customsforge.com/topic/11210-lyric-tutorial/ about FX sorry but im not good at this:P oh and i wanted to say about the song you are working i tried to see how big is the role of guitar 3 and 4 and if can it be mixed with 1 or 2 like i do somtimes~ well after listening few times to the song i think in my opinion that guitar 1 and 2 can hold the whole song,3&4 dont sound too much like a guitar but rather like a background synth and i guess thats why i could skip making track for them,like,i think i would maybe put few parts of 3 or 4 on the empty space of 1 or 2 but thats me:D its your choice if you want to chart synth parts aswell,i usualy dont:) when i see more than 2 guitar parts on the GP file im usualy like- dem,gotta check the live vid now to see what they actualy play and not all the stuff they added on the studio:P i try to avoid making more than 2 guitar parts when i know there are only 2 guitarists/guitars so i go check the live video if there is or try to to hear what s the main thing i hear on the song and thats what i add to my CDLC and that probably what i wanna play/ppl wanna play:) hope i helped sorry for the long post:P
