Ok, this is the way that I use Ableton. I'm not a DJ/Producer, I just enjoy playing with music. It took me ages to find my way around Ableton Live so if the following can point anyone in the right direction then it's all good!........
You've opened Live 6 and you should have a screen that looks something like this.
This view is the default with vertical sections for adding samples, and is called the 'Session View'. For the purpose of making an A+B bootleg you don't need this, so click on the circle at the top left with the 3 horizontal lines, that takes you to the 'Arrangement View'.....
The Arrangemet View below is where you'll start creating!
Along the top, the imporant things you'll use are the 2nd box from the left where it says '120' in the picture, click and drag here to set the tempo of your tune.
At the right hand side there's a %tage meter and a 'D' box, basically this shows a percentage of how hard your computer is working and if it get to 100% you'll get Dropouts in the music, hence the D! Just be careful how many effects you are using and you should be fine.
The first thing to do is locate your the tracks or samples that you want to mix, as shown above there's 3 buttons that you can preset to different folders where you keep your tunes.
Simply drag and drop the samples in to the horizontal tracks on the main screen, for this exercise it's simply A+B, so one instrumental and one acapella.
The first time you drag a clip into Ableton it will try and work out the BPM and start point of the track, and will insert markers where it needs to keep the track in time. This is done automatically, not like Acid where you have to beat match the track manually! The other good thing here is that even if it's a live recording with a crap drummer Live will try to even out the BPM all the way through the track.
But, make sure you check as it doesn't always get it right!! See below...
Below is a close up of the track information boxes. As a rule always turn on the 'Hi-Q' and 'RAM' buttons. The RAM button forces Live to pre load the next sample into your computers RAM so you don't get any dropout in your mix when a new sample is played, and the HI-Q uses better signal processing, making the overall sound much better. The downside to both is that if your computer is low on CPU power or RAM it might not be able to cope!
Next is the drop down menu with beats, tones, etc....Your going to have to experiment here, but basically the 'Complex' option combines all of the other 4 into one and generally gives the best sound, although it is very CPU intensive, especially if you are mixing more than 2 or 3 tracks.
To the right there's a detailed view of how Live has guessed the timing of your track. You can click and drag to zoom and move around. Live is pretty good at guessing the timing, but it doesn't always get it right....If it's not right first time, the first thing to try is setting the start of the track manually, and there's a 'warp from here' option if you right click. In my experience that usually fixes any problems. But if you need to you can adjust individual time markers, or even insert new ones if you need to.
Once, you are happy that you've got the timing of all of your tracks correct you can start mixing them together. Now I'm not going to go in to detail of 'how to make a bootleg' because that's down to you and this is an Ableton tutorial...
A couple of things that I have done with this particular mix is to extend/loop the intro of each track and fade the volume of the acapella up. I've also adjusted the pitch of the acapella down by 1 semi-tone. (Both shown in the picture.)
I hope that sort of covers how to get an A+B bootleg basically set up in Live 6. From here it gets a bit more complex but here's a little intro....
Ableton Live has 100's of audio effects built in to do pretty much anything you want with sound. Any of the effects can be dragged and dropped into the bottom box for each track. You can also 'chain' multiple effects by lining them up one after another.
Purely from a mastering point of view, here's a couple that I use...
The 'DJ master channel' can be applied to each individual track and gives you control over volume, EQ and reverb of each sample. You can automate any of the effects using the track menu on the right (Note that 'Sat Gain' has a red dot over it's dial in to bottom box, meaning that it has an automated change set (Shown by the red line on the track view.)...
