5000 Low Pass Filter

I've been importing some of my MPC 2500 programs into the 5000 (OS 2.0) and have noticed despite a lot of tweaking in the Program FiltLFO tab, a lot of my samples click and pop when played through the low pass filter. All the other filters sound fine but for some reason if the low pass filter is applied, the sample clicks/pops at the start of playback - particularly when a pad is repeatedly pressed. I've checked the samples themselves to make sure they are zero'd at both ends but regardless, I've never had this on the 2500. Is anyone else experiencing this and/or knows a workaround?

Thnx

Could you send me one of those programs+samples so I can test? Might be a bug.

no that happens with me too. its like you cant touch the res. depending on the slope and frequencies. and allot of the time, were it sounds good thats when you get the pops. i tried using the fade out in sample edit ,but not really sure how to use it to its potential yet? anyhow (unsuccessful) I also tryied chopping but everywhere you chop you get the same effect! pops n cracks!

I still would like to receive an example, so I am sure what you are talking about.

i think hes using bassier sounds as well. and only when you tap rapidly otherwise its not noticeable if you let the sample play out then tap again were your sample is now lifeless.

i was also thinking it could be the samples signal could be to strong. and maybe to loud overwhelming low pass not sure. that would be weak. anyways ima keep experimenting. hope you find a cure!!!!

It also happens with anything bassy regardless of the filter, despite playing with the sample ADSR i.e. an 808 kick or low tone will do it . This sample in particular is a loop containing drums, guitar and bass that has been chopped over multiple pads which have the low pass filter applied to just bring through the bass. Hit a pad and you can get away with it, but try and play a bassline and you'll hear the clicks and pops. All the samples played back fine on the 2500 and look and sound ok in Soundforge i.e. not too loud and zero'd at both ends.

I'm going to record the same samples into the 5000 direct and import some other sounds that were not recorded on the 2500 to see if the same applies to them. I'm presuming it has something to do with the wavs as I cant replicate it using the loopmasters sounds supplied with the 5000.

@ SCD: I'll hook something l8r re: a sample and some programs for you to play with.

Yes, thanks. That would help.

I have encountered exactly the same problem. Just turn down the low pass on a longer saüple and you hear a click at the end of the sample.

Have you tried turning down the Master Level of the mpc5k? I think that might help the problem. I had the same problem once on the mpc4k. Turning down the master level, clear up the bass and also midrange destortion and clicks when tweaking the filters. I keep the mpc5k's master level at -6db.

Yeah, same thing happens to me. Pretty annoying. I was thinking I may have to take it out in Pro Tools, but that's kinda whack you know?

Have you tried turning the ATT(enuation) parameter down?

That limits the level going TO the filter.

Hey Steve! Nice to see you around here

Hi Boele

I have the same thing too. It categorically only happens when you're playing a chopped pattern - it does not happen when you are playing a single sample - I've come up with a workaround but it still really sucks to have to do this:

Basically, take your chopped pattern that is suffering from pops and clicks, and DON'T run it through the filter yet - instead, resample it so you can play it as a single sample. Then, you can run this sample through your lowpass filter without any pops or clicks.

Another workaround would be to export to a DAW and remove the clicks with a suitable plugin, but that thought makes me shudder!

I really hope this is sorted in a future OS update.

(I have exhausted every possible solution BTW, including all ones mentioned previously in this thread).

hi there!
I posted a filter bug earlier in VA synth, about model1 low pass. I cracks and pops at low cutoff freq and fast filter envelopes. it gets even worse if you turn on the mono mode. the sad thing is that model 1 lowpass is the best analogue sounding filter.
here the topic I posted: viewtopic.php?f=29&t=115040&start=0&hilit=filter+bug
the filters are the same for samples.
