Sampling from the computer to the MPC?

Hi, I have a little problem when I try to sample sounds from my computer to my MPC 2000. I have connected the outs of my soundcard to a mixer, and the outs of the mixer go to the ins of my MPC.
But, there is always a noise when I sample from the computer to the MPC. I uploaded an example to show you what kind of noise it is: http://www.zshare.net/audio/91949911e8ddbb3a/

Anyone had a similar problem?Any solution? Thanks!

I'm guessing computer interference being picked up on your cables.

I get the exact same sound if I have certain channels open on my mixing desk (24 chan A&H) which is placed above my PC on a stand (should move it really). I can hear the digital noise more when I move my mouse.

I've had the exact same issue since I can remember, how to get rid of this

I found this thread with some solutions, but it seems that it can come from different things...I guess it's not easy to resolve this problem.

Computers tend to have a lot of background noise. I figure the best bet is to save your samples onto a floppy disk or media card of some sort and load them up in the MP from there...

or you can burn a CD with all the tracks and stuff you want to sample and sample it of a CD player

thanks for diggin this up imma check it out...never had this issue with mac computers, pc's only...and my latest I7 build is grounded..I screwed the ground wire from the psu to the case chasis myself and this shit still happen. but it only seem to be the case with integrated sound cards in my case

lol, that thread ^^^ had no useful info. (lick your cables, wtf?)

Imo,

This has something to do with the digital clock on your computers internal soundcard. HP laptops are NOTORIOUS for this issue, but if you run the laptop off of the battery, no noise....Im not an electrical engineer, but almost all computer soundcards are not made for recording, and barely usable for outputs. The only sound that comes out of my internal soundcard is the Apple chime on power up, lmao.

@Koncept: As far as grounding your chassis, are there maybe some internal components that also need to be grounded? Ive never had this problem personally either, but only because I cant **** with Windows.

I use an RME Fireface 800, externally in my rack. I disabled the motherboard soundcard since day one. Maybe it's because my firewire cable is running near my computer? I only get the digital noise issue when using groups 3 and 4 from my A&H GS3 though... nothing else. The GS3 is notorious for bad grounding though... so.... I'll have to trace through my cables at some point to find out why it happens on those channels. Maybe because I have my dbx 118 inserted on that grp. Could be owt tbh... I've got a ridonKulous cable mess going on around me from all my outboard gear

The RME stuff is all good, and its really weird that only the group outs on the board are acting fishy....Are the outputs (not the cables) balanced?

Unless your running unbalanced cables a long distance (15'+), a big mess of cables shouldnt be too much of an issue, unless its sitting on top of a wall wart or power supply for something. I would move the mixer away from the PC too if you can.

I didn't read the whole thread but I've heard there's a way to capture the sound within the PC via a freeware program....then you could transfer the sound to your MPC if you have the ability to do that. I can't remember the program...I'll have to look into that.

audacity is good.

you know I always assumed since everything is connected to the psu which is grounded to the case chasis that would make everything else connected to it grounded as well, am i wrong ?

and I also got that buzzing noise when I move the mouse on my pc and it is using built in sound card, I dont remember if it was there when I used my firewire interfaces...all in all this is reason why I ditched PC music production in favor of apple macintosh, too many fuken issues with those pcs and time wasted troubleshooting

Yes and no. Small gauge cable isnt the strongest stuff in the world, and its REALLY easy to damage a connection on install. Plus, I dont trust molex connectors, ive had a pin slip out of the plastic connector housing and short out and fry my whole PC...No fun. Manufacturers also **** up quite a bit on cheap chinese mass produced computer crap, so solder joints could be loose, you can verify with a multimeter if you have one. I know its overkill, but better safe than sorry...

Exactly! I worked in telecom and was in a windows environment up to 16 hours a day, 6 days a week....And then Vista came out , and I spent my off day running antivirus and defrag and **** with security updates and it was just too much BS. I quit that shit like Ricky Williams quit the dolphins, copped an iMac and PT and went to school for music.

way I do it is chop up songs with mp3edit (free program, search for it in google to get the link), convert em to .wav using itunes, then copy+paste and put em on my memory card. you can use a usb cord to connect the mpc to your computer, then turn on your mpc, go to save/load, hit f3 or f4 (the one that says usb) and make sure the cable's connected. then open your driver and it should say "mpc1000". you can copy+paste to the internal memory or the memory card.

Truly shocking method
