Litmus Test Wav request **Resolved**

By labcoats Tue Nov 22, 2011 1:09 am
Greetings,

Could someone with an MPC4k please do me a favour which wouldnt take long.

Simply:
Sequence up a sound with a very fast attack such as a metronome sound or a rim shot @ 120bpm - hard quantised for 8 bars @ quarter notes. Record the file directly from your MPCs stereo out puts in to your daw, do not edit the wave file in any way. Then send me the wav file



So to recap
Record 8 bars @ 120 bpm quarter notes EXACTLY (4 beats in the bar). Dont forget to hard Quantise
Use a sound with a fast attack
Record file in to your daw
Do not edit the wav file in any way
Send it to me in wav format. Do not convert to MP3


Im also going to post the same request on the MPC 5000 section as I want to run a test on the MPC5k as well.

Anyone willing to do this for me?

Explain what you are trying to accomplish instead of just telling people to do something, let them decide.

btw, your other thread, locked.

Lampdog,

Im not telling anyone to do anything. I have kindly asked if anyone would be willing to do me a most excellent favour as I state in the thread title.

The reason is to check how accurate the MPC4k clock is.


Was it you that locked my MPC 5k request?
If not can you point me in the direction of who I message to have the lock removed?

The test you describe actually comes from here...

Not all MPC's were tested, so I guess this is what you want to clear up.

http://www.innerclocksystems.com/New%20 ... itmus.html

http://www.innerclocksystems.com/New%20 ... Watch.html

The results have been published here in various forums.

People will believe what they want to, its their right. In many cases perfect timing is undesirable, minor timing irregularities are difficult to establish by ear alone.

Innerclock Systems have professional gear to conduct the tests, their business relies on timing and synchronisation accuracy.

Im very familiar with the Litmus test but becasue there are no test results for the 4k or 5k, and as I dont have either it would be great if someone would take the 5 minutes to record the wav file. I have searched the forum for Litmus 4k test and cannot find anything. If you know of a link that would be great. Btw, no special equipment is needed to perform the LT. Any audio editor capable of displaying samples will produce definitive results. I have tested quite a bit of gear my self, but not the 4k or the 5k.

I appreciate what your saying but I strongly disagree with your point that a bit of irregular timing is a desirable thing. Random slop in a machine designed to keep accurate timing is not a desirable element in the slightest. That is a myth that has been paraded around forums for years based on nothing but voodoo groove science and it really is time that nonsense stopped. Its obvious why the MPC 3k and the 60 groove mercilessly. They both have super accurate internal clocks. The 3k has a max deviation of no more than 4 samples. Amazing!



Come on guys, a little less cynicism and help me out here so I can decide which one to buy.


PS
Can you please unlock the thread I posted on the 5k forum. I would really like to run the LT on the 5k as well.

I apologize, and done, unlocked!

Have fun with that. Buying either will give you great joy.

Results for the 3000 and 60 were posted in that forum by myself recently.

I'll keep an eye out for the result of your 4000/ 5000 Litmus tests.

THanks Lampdog, much appreciated.

Litmus test results for the 4k (especially)
would be excellent. The 4k is actually my
preferred mpc,

My gut feeling anyway is the 4k is very tight.
Hard
to tell on YT tube videos but a couple of things I have
heard do seem to ooze the karma 8)

The MPC 3000s clock is truly impressive. Its damn near sample accurate. Only 4 samples of deviation which is pretty much undetectable. The 60 is also amazing with around 14 samples. Considering
the age of both of these machines makes it all the more amazing. Seems back then
they placed high importance on the internal clock timing which definitely cannot be said about new gear made today. I dont believe there would be another piece of hardware on the market both old and new that could compete with the 3000s internal clock.

My only beef with the 3000 and the 60 would be the sequencer. I have an ASQ10 which is great but I do find the sequencer a little basic for my needs. Ten years of using a DAW has spoiled me I guess.

I made a beat the other day that was so tight..that it'll make a fool dance walking on a tight rope. 4000 is the best MPC ever...IMHO.

Just look at Havoc..He swore by the MPC 3000..

Til he got the MPC 4000 in his life..

Neither of those videos give any idea whatsoever about how tight the MPCs internal clock is. Think about it. How can sampled loops tell me how tight the sequencer is. Even the most sloppy sequencer on the planet could pass if all its doing is triggering a few notes here and there once every bar or half bar.

The real test is when no loops are used and the sequencer is triggering every single drum, bass note, synth individually.

Yeah, when I saw the LT results for the 909 I was surprised, but not shocked. I only ever programmed in to my 909 a few times when I wanted to use its quite heavy swing. In general I felt I got a better groove programming it from the Atari running Cubase. At the time I had no idea why I seemed to like it better sequenced from the Atari. Now I do

The Lt results for the 808 are interesting. I always felt that while the sound was easily sampled the 808 its self just feels much better when its sequenced from its own engine. Its a combination of its internal clock and the fact there is no serial midi queue. So when a snare and kik are triggered internally at the same time they are played bang on together unlike midi which spits notes out in serial mode one at a time. This is why the MPC 3k and 60 are so very tight as well and I suspect the 4000.

Still no joy with anyone coming forward :cry:

Im easy about not doing the test my self so if anyone else would like to do it and post the results, much appreciated.

Come on, someone else is surely interested in how the 4ks clock stands up.

Im betting a maximum of 20-25 sampled deviation 8)

And if anyone is interested my test on an MPC2KXL produced 67 samples of deviation. Not shock horror, but not brilliant. I guess thats why i never really geled with the feel I got from the 2kXL.
