Sequencing Problems w/ 1000???

I keep having sequencing problems playing live with the 1000.
After a short while when I start to loop a track(i.e. midi or core)
other tracks drop out for the length of the sequence or won't play the 2nd time through. It's really annoying in a live setting!
Any thoughts or has anybody experienced this?

Are you manually looping your samples and then time correcting your one shots? if so you will loose sync with your midi'd controlled beat versus your sample portion. In this case I usally turn off the time correction completely for all sections.

I hope this answers your question. You need to give us more detail on what exactly you are doing

Thanks Drew,

That's not my problem though.
This is my exact set-up:
mpc 1000
midi 1 out to Micro Q
midi 2 out to Nord electro
midi guitar into mpc (this controls all my keyboards)

So when I play live, I keep playing and looping everything live.
I ussually always have the time correct on.
example:
-I manually play a beat in overdub while the machine is looping 2 to 4 bars. Sometimes I will play loops as well.
-I keep adding more loops on different tracks (percussion and what not)
-Then I started looping the midi'd keyboards via my guitar, via the mpc.

-So after a while when I loop a track in overdub over previously recorded loops, some tracks will drop out for the length of the sequence while recording. Also, when I play a keyboard part, sometimes it will not playback the second time trough the loop after I have recorded it.
It's really ****. My 2000xl never had this problem. I have picked this 1000 apart trying to find a solution and have talked to Akai. No answers.
They say my machine is broken, but I think it is a bug. I think I am doing some heavy duty stuff on the machine and it just can't take it.
If I stop and then start the 1000 it seems to stop for a while. I have incorporated a chaos pad, so I can grab a loop on it, stop my machine, release the chaos pad and start the 1000 again. This has been my only solution.
Not to sound arrogant but I think I am doing some pretty forward thinking perfomances with the 1000 and nobody around is doing it like this so it is hard to get feedback on my problem.
Any help would be greatly appreciated.
thanks,

maybe you're running out of polyphony...

that makes sense Matt, but when I stop it and start again everything runs just find. Maybe it's a polophony issue in overdub mode? I figure it is just to much for the machine to handle.......why? I have no clue?

I think that can be explained if you have a lot of tail at the end of your samples, (a crash symbol for instance), if you have 16 one shot stereo crash symbols in a row, and each one is 6 seconds long, by the time you get to the second bar, your polyphony will be all eaten up by those. When you stop and start again, it wont be playing samples from the previous bar, which would explain why it works when you stop and start again.
Also, if you find that the issue is with the sounds on the mpc, and not with the sounds you're controlling on the external gear, chances are it's a polyphony problem.
One way to avoid the poly limit is by keeping your samples mono rather than stereo.
hope that helps mang!

Thank Matt,

That could be part of the issue. I ussually keep my samples tight and mono, but I often have a lot going on at once. I wonder if the poly limit effects my external midi devices. It seems that theoretically you would only be allowed a certian amount of midi notes. I also wonder if having a bunch of muted tracks that I am finished with but still remain, while I keep creating more, effect the performance of the machine. I feel like I push it pretty hard.
I have never had any issues with my 2000xl though.
I wish I could fix this.....because all the new features on the 1k kill it.
You can do so much while the machine is running....on the fly that you could not do on the xl. Plus the 1k fits in a frickin back pack!!!

no prob John,
Is it your external gear that you're having trouble with?
I wouldn't think that there's a limit on the midi out (beyond the standard midi specs), and if you're muting your tracks on the mpc (rather than on a mixer or midi controller), those tracks aren't sending out any midi. I once had a problem with external gear when send midi thru a piece of gear that had a software thru/merge that had trouble putting all the data through to the target synth. Or maybe it's a bad midi cable. Or maybe you've got a bunk mpc 1000? If that's the case hopefully it's under warranty.
I know what you mean about the killer features, sampling shig while the sequence is playing is wicked! Also that midi guitar unit sounds like fun.
One thing that just occurred to me, is that if you're recording a lot of tracks/data without stopping, there could be an issue with the temporary memory that it writes that data to. You know how when you're recording midi, you can only undo to when you last stopped? I'm just guessing, but perhaps the problem is that there's a limit to the amount of data that c an be held in the part of the memory that records midi. If you're really pushing things that coud be it, are you recording lots of CC data? might need to stop your loops every so often, if that's to deal.
