if this has been covered, i sincerely apologized but i attempted to search the forums extensively to find an answer, and even talked to a few guys at guitar center..... so here is the problem:


I've noticed when recording into protools the mpc has a very low but noticeable feedback/buzzing noise that is evident in empty spots of drum tracks (like between the snare hitting on the snare track) but it also effects the spots where an actual drum is hitting. Example: when i'm mixing and i put a compressor on a clap or kick to get their level right w/ the mix...when the kick is boosted, so is this ANNOYING hiss!!! and its to the point where i can't get my drums knocking without the hiss also coming more into the mix as well.


I have some expensive monster cable in the mpc1000's stereo outs L/R and into the mbox. Also should be noted that when i do this same thing with my roland fantom, there isn't this same annoying feedback. everything records in crisp and clean.

is this a wiring problem? can it be fixed easily? Just wondering if anyone else has ever had this.


I have included two images and an mp3 of some drums i recorded as an example. To show you the feedback noise, i have lowered the volumes of my drums by a lot so that the feedback shows up without the drums blasting in your ears. You will have to turn your volume up though. Some might think "well why would you have it that loud anyways" but to be honest it affects all tracks i record out from my mpc later down the line, and its such a hassle to go through all the blank regions in protools and have to erase their wave form because of this feedback.


The first image shows me hitting play on the blank area of the wave, and w/ the volume boosted on the right you can see the graph picking up a signal. It does not do this w/ the fantom, which gives me no noise.

This 2nd image is a zoomed in view of the blank space that was showing feedback on the mixer, as you can see there is some sort of noise here being put out by the mpc

here's a sound file i've included w/ the drums turned down so that you can hear the hissing noise

how loud are your drums?
are they normalised?
what is the Master level of your mpc set at?
are the drums loud in their programs / mixer settings? or turned down.
What are the velocity's on your drum hits?

need more info to help - but i'd check those 1st
sounds like you gotta level problem

By enzo Mon Dec 03, 2007 10:49 am
lookin at the main volume knob, its at like 10:00 on a clock

master level is at 0db

my drums and everything sound fine its just there is a strong feedback coming from the mpc......as soon as i enable a track in protools to record from the mpc, the noise immediately cuts in (a quiet but noticeable feedback noise)

you should be able to hear it on that mp3 i posted, again i only lowered the levels of my drums on that example mp3 so that you could hear the feedback i'm talkin about w/out blowin your ears out

i believe CTRL+U gives you strip silence. This will allow you to command pro tools to remove all of these spots without having to sit there and manually cut out the noise parts. you can also try running some type of gate in your system. And as the others said check your levels.

it could just be some normal noise level..

Theres always background noise.. in some cases more or less.

If you turn down your mpc "main volume" is the noise still there?
If so, turn the knob more than 10 o clock without disting your signal.

This should make you use less compressor to even out the signal with the rest.. = the noise isn“t compressed so much...

If not then theres just error seeking left.. try switching cables etc...

Are you using an Mbox by any chance?

oh yes.
get an spdif cable and hook it digitally.
then you get zero noise.

By enzo Wed Dec 05, 2007 1:54 am
so with the digital spdif cable i noticed it's just one cable.......do i still have the option of choosing whether i record mono or stereo?

yeah, 1 cables all you need for stereo or mono
