Anyone Ever Notice - When Pitching 2 Tracks (pg. 2)

Well I mean it makes sense... when you produce a track, you set the tempo in the sequencer in your DAW app, and that's how it comes out!
Lots of people produce tracks at 128 BPM, or 129 BPM, or 130BPM :)
If you really want to "cheat" and have CDJ's with decent BPM detection...
When you start your mix off, set the pitch so that it JUST crosses over a BPM boundry. For example, if you are starting at 128 BPM, move the slider up until you JUST crosses into 129 by .02%.
Next track you mix in, do the same. It will likely be pretty close to perfectly matched. On the CDJ-1000's the BPM detectors are surprisingly accurate. You still need to check by ear of course.
Is it cheating? I guess not if you already know how to beatmatch. You can't rely on it. I can play vinyl too, so I know I don't need to cheat. But if I'm recording a demo or playing out in a loud club, what the hell, it gets you there quickly and feels like an insurance policy :)
As you play more with the CDJ's, you'll notice certain crossover points where you go from one BPM to another. |

| its not cheating. I think the only way you can cheat at beatmatching is to have someone else match it for you. As long as you get em matched up, you are good. |

| Thats a good technique if you have an accurate BPM counter. My CDJ-200's arent too accurate sometimes...might be 130 BPM and it reas something weird like 80 BPM which pisses me off...eventually it gets accurate but after two or three minutes . |

I've done the same thing, again, by accident. When adjusting the pitch of my incoming track, and I get it just right, and i realise it's on the border of the BPM boundary when it's just matched. So I touch the track playing and realize it's just a touch off the BPM boundary too. Sort of the same thing as I mentioned originally......but different. You get to notice this sort of stuff with CDJs. I love them. |

Heh, I'll do you guys one better:
Keep in mind that 95% of tracks are produced with a nice rounded number for their tempo (i.e. 126.00, 127.00, 128.00--no tenths or hundredths).
Now here's the fun part: the pitch ratio for plus or minus 1.00 BPM is right around 0.80%. It can vary ever so slightly due to natural variations in tracks and their sequencers, but for the most part it is dead accurate.
That means if your mix is running at 128bpm, and you're cuing a track that is 125 bpm, all you need to do is set its pitch to 2.40% (3bpm * 0.8% = 2.4%) and you're good to go.
I didn't calculate this or anything, I just noticed the patterns over time as I kept spinning. |

| Yeah its pretty obvious math. When i was mixing with the tech's i would slide the pitch up and down to beatmatch, then just ride it a bit.. but now that i use cdj 1000's i no longer have to do that, and with the .02% on the 1000's there is no such thing as riding the pitch. |

I don't know about that. When I run the songs on a program called Mixed in Key which determines the tunes keys and BPM's, most songs end up with decimal places, and by most I mean all the ones I've run on the prog. Anyway, this is still a good idea due to the fact that you have a better idea of the range between the BPM's small increments. |

Haha, the reason that the Mixed in Key in showing you decimal places is the SAME reason that the CDJ's aren't perfect at BPM detection. They are just running algorithms to "guess" the BPM as accurately as they can. It's those algorithms that are innaccurate, not your tracks.

That makes sense. I created a track on Fruity Loops and I set the BPM to exactly 135...then I ran it in Mixed in Key and it read 134.89...so, ing computers. |

Yeah, but the decimal places are usually something like 127.97 or 128.02. I play with new tunes in Ableton if I haven't yet had a chance to burn them, so I see it all the time. |

| Yea...I'm purchasing a new pack of CD's tommorrow so I will do alot of burning and practicing. I'll make sure to run them through the prog and see the results play out on the CDJ's. |

| I love it when this happens. Makes beatmatching hella easier. Especially when youre like, I bet these tracks sound good together, and they do and theyre the same bpm. Its like a free blow job. |
