Many great ideas have already been shared..
Before starting - I have gotten in the habit of putting equipment back in its place, hooked up and laid out. This is especially important during the summer when I am out performing a lot.
Starting with an idea - could come from daily practice, in performance, sound check, during a songwriting session or the like.. I always have an idea for a name now. That helps me to focus on completing XXXXXXXX. I put up a chalkboard in my little room, and on it - I put the song, who I would like to invite to help if I get a sense of what will fit, then a tracking done date, mixing done date, and a to master date. I find if I can see it as I walk in, it prompts me to get going. The name also reminds me of the emotion or purpose of the song.
1 - Start with a template. 4 audio channels and (used to be session drummer) an AD set of channels. 3 tracks are setup as guitar inputs - one for acoustic, two for electric. 1 track is setup for bass. The effects are turned off - just putting them in there because 6 times out of 10, I am going to use them. I also have the click track setup to run in the template. As I am starting a new track, I name it, assign it a color, assign it to submixes - and put a picture on the track. As I am adding tracks, I tend to move them physically into groups that make sense to me - drag and drop.. The whole part of this in my little write up is - IF I AM FIDDLING, I AM NOT WRITING.. I spend literally minutes in fiddling, and hours in WRITING.
2 - Record the basic idea - I usually hear a verse and chorus in my head well before I start, not always, but more often than not. I noodle around with a basic idea at least an hour before I start. Recording the basic idea starts with an electric guitar 70% of the time. I find I lay in an intro, a verse and a chorus almost always. I comp in a few takes, and then relax - time to choose, but most of the time its first take that I use as my lighthouse, if you will. Take lanes are so intuitive and fit my way of thinking and reacting, perfectly. When I am done picking the takes, I relax and loop through the basic structure many times just to infuse the idea as a reality now.
3 - Next, I walk through AD, and find the closest thing to what I can hear in my head, or what fits the emotion or purpose for the song, and lay the intro, verse, chorus, turn, interlude or what have you, down - using mostly supplied midi snippets. I want to thank the artists who put together the midi tracks that I use - you know who you are AD and Session Drummer folks. Too funny - percussionists hit things with sticks, and hit you over the head when its a perfect groove.
4 - I track out the entire song structure for guitars, sans leads. No mixing yet - I find if I like it as it sounds when it is laid down, when I mix it into the song structure and add audio effects, I really am going to like it. This takes time, but X3 has such a superb tool set as to take my mind off of the box, and keep it into the performance. Really - when you think about it, you are probably sitting and fiddling all of about 10 seconds in the box and get 5 minutes of performance for each track. Thats a hugely GREAT ratio in terms of song writing productivity folks.
5 - I lay down bass track - single. Just like number 4, I really dig X3 and how its so easy to comp record. While I am not a bass player, to me - getting this track right is dead on important, so when I listen back, I always look at the graphic eq spectrum analyzer. Its a great reference tool for my eyes, and I rely on it because my ears get pretty fatigued after a few hours of work. Besides the Twin and Marshall bending my ears in 4 above, the SWR I use puts a fade in my ears something fierce..
6 - I go back to AD and add or subtract simple parts like single crash hits, or mic placement - or room levels. The midi editor screens and smart tool are employed a ton here.
7 - Now for the vocals. I write them after the basic rhythm parts are down. Thank goodness for the loop tool. What would be really cool is to have a loop, then pause a user supplied number of seconds to write down what popped up in my head. I know I could track the words, but I don't.. :o) I generally write lyrics with the person I chose to help sing. Something about their influence in the lyric that propels them to sing using a higher level of competency and awareness. Its worth it to me to share credits for them infusing passion. One thing I like about X3 when I get to this point is the ability to make fast mixes, and versions - I think its rare for me to have just one version during the vocal process. I can hear where the song is headed, but sometimes the singer and I take a left turn, and conversely I have been very thankful that I had the original point a week later.
A note about the power in editing - as I take left turns, it takes very very little time to move a section here, double a section there, delete a section in another place. The point is - once the tracks are in the box, you have this supurb editing functionality that allows me to shift every measure if I want, to a completely different measure. I haven't done much with tempo changes, but there are great ideas that come from the user forum on how to do just about anything except find the talent button.
9 - Leads, comps, leads and more leads. Performing the rhythm and bass parts tend to be more mechanical for me. The analysis part of my brain stays lit most of it. Now is the time where I have to shut that damn analysis tool down, and turn up the creative part. I do not know where I would be without comping and having loop points. Its not uncommon for me to take an hour with one particular guitar setup, then another hour with a completely different setup. Thank goodness for putting the room in order first, then kudos to my GCX and GCU tools.
The song writing is done. I will have other performers in, but to me the parts I listed are part of creating the song AND as a bonus - rough tracks are in the box. Now Craig - you wanted to know how we write songs using X3, but to my mind, the vast power of this tool set is the creative ability to mix and help in the mastering process.
