those were my plans finsta. the instuction manual sucks though. only got to the sampling part. no sequencing yet. should be easy right? using it for drums should be fine. then the 4000 for everything else.

Yeah... the major thing to do when working with the SP... is not to over complicate things.... by monday, you understand it 100%... the biggest issue I ever had was syncing and doing passes with SMPTE (and the buttons are a little makeshift... one of my pads/buttons is still broke)... I haven't messed with the SP in awhile... but if you have questions feel free to send me a message... I'll boot it up and help ya out... the manual is horrible... another tip is to be organized... I have tons of floppies... and never named my sound names (more or less samples I chopped)... it's really no biggie, but if I were just starting out... I'd do my best to archive and cross reference everything to save from later headaches...

ENJOY!!!

P.S. if you ever get a chance to use the SP along with an SSL and 2inch reel... you understand why Dr. Dre hates digital and loves the warmth of Analogue... shit I'd still be going the analogue route if the reels weren't so damn expensive for 15 minutes worth of tape. The drums thump and rumble so **** hard... you start coughing up phlem... no matter how punch drunk people think they can make their beats... it cant compare to the SP.

Ok ok, I know that it's superavanteguard and too picky to say don't sample the 1200 with the 4000. But really, it' true. Ok yes, you will have some of that SP sound and truncation going on. But, the oversampling that alters the white noise in the SP1200, is totally refined and of a much higher bitrate in the 4000. When you sample into the sp, you go analog to digital via converters in the SP which give it a particular sound. So, what you are doing when you sample the SP1200 to the 4000 is:
going d-to-a out of the sp, a-to-d into the 4000, then d-to-a into a board of whatever cable that goes to your multitrack, or 2track to burn a cd, which means it's getting converted again. When really, you could just go out of the SP1200, into the board or multitrack, converting only 1 additional time to get it to multitrack or CD.
With that 'old school' sound from the sp, you have 'crap' in the signal, which comes from that technology's innability to correct the audio anomolies which arise from lowbit sampling. Oversampling bridges gaps in the digital 'picture' of the sound that create white noise to fill up these spaces. That is what makes the SP sound the way it does. Not only that, but the particular math the EMU used to do this on that machine, combines with the parts like it's outputs, etc, and the assembly process to put it together, all total to make that 'sound' you like in th sp.
Now, when you sample with a high end sampler, it's gonna have it's OWN algorthms and sound. In the case of the 4000, you have a crisp and deliberate sound. Very pristene. Now, that **** is gonna pick up everything in the SP sample, but the gaps in the conversion on the 4000 are very minute. But unless you sample at 96k, they can still be noticeable, so now youve got a brand new sampler, trying to make up for sapces where there was white noise that you wanted in there from the original sample. What I'm saying is that the 4000 is not trying to correct the SP, but in trying to correct it OWN 16bit samples it's gonna have it's own brand of noise in the signal. And AKAIs current brand of sampling 'crap' in the conversion is not known as a warm and fuzzy tone that 'everyone's tryin to get' like the SP is. So essentially, you gonna add overly digital crispness to those SP samples; the very opposite of the thing you are attemting to achieve by using an SP in the first place. Now, you can tell me all you want that, indeed, the differences in the human perception from sampling once, to sampling twice, ete etc...and I feel that. I actually DO sample my SP1200 with my MPC all the time, for conveniece. But I much prefer to go as DIRECT a path from an audio source to the recording medium is possible. Now, when you talk super high end gear, that's not a problem. Why put vocals direct to protools from a preamp when I can go through and LA2A compressor? But I would NEVER go to a 4000 with vocals unless I absolutely had to. It's not gonna enhance it, except for convenience.
It's gonna detract from the sound at the end of it all. But this is just theory,
and if you got to do it that way, you got to. But just keep in mind:

People will tell you that "Yo, a sample is a sample. Once you go to 16bit CD quality, it's a perfect capture of the sound."
This is incorrect, and yes, you can tell the difference. Thats why, yes
you can tell the difference between your SP1200, and someone
resampling to 12bit medium quality with the 2000XL.
That combined with the fact that you will have a thicker signal the less gear you go thru is a solid argument for using each machine as it's own machine.
Damn. Now I done bored yall to death. Anyone still alive?

So basically that means if you make beats on the sp1200 you have to record it onto a 2" 24 analogue tapemachine or else this "correction" is gonna happen? I mean... If that shit is correct that would definately happen in any "additional" DA-AD transfer, right? So in order to really keep that sound you have to use all analogue gear, even with the mastering. Otherwise what you're saying just doesnt make any sense.

Not trying to pick a fight here but it just doesnt sounds right to me. You dont present any facts either, its basically just speculation on your part. If not, please provide with some facts for this (with source), as it would be an interesting read.

You use the SP to get that rugged 12bit sound. By using the 4000 to "re"sample the SP you will get a cleaner, less rugged sound. Besides alot of the SP sound comes from its outputs.... :wink:

Yeah, that's exactly what I was wondering....

Hmm, I'm not sure I get it. Are you saying that the 4k adds crispness to the original dark 1200's sound? So the 4k is actually coloring the sound? I always understood that the 4k is a very transparent sampler, with a wide frequency response, but not coloring it. I also don't understand where these additional crispy high frequencies would come from.

Otoh, of course I believe you that the 4k cannot correctly reproduce the 1200 sound. So maybe the 1200's digital artifacts are in a frequency range that cannot be recorded by the 4k, because they're > 20k Hz? If I understand trupro's report correctly, the problem is gone when sampling at 96k, which would explain things then.

I'd sure like to hear the sp1200! But let me first get that mpc4000, finally.

:wink:

How? Please explain that. You're actually trying to say the 4k "cleans" the sp1200s outs when sampling directly from it? The 4k just samples it as any other source, it doesnt care about what processing the sample has gone through prior ending up on the 4k.

The point I made was if that you sample the sp1200 outs you're gonna get that sound from that sample, the way it sounded right when you played it on the sp1200. If the 4k is totally transparent as it is claimed to be then how would the sound be any different?

I think that the 12 bit recording is converted to 16 bit in the MPC. That is could be the reason for the change in sound. I am not sure it will take some investigating.
Have you tried to sample the SP 1200 to your computer and then transfer thru aksys and see if there is a difference?

Yeah a combo of those last 4 posts really does it justice. Every peice of gear colors the sound, whether it's analog or digital, 'good' or 'bad' depending on level of quality, combined with personal preference, etc.
But alot of people agree that warm and musical 'sounds better' (again, opinion) than 'harsh and digital'. I'm definately splitting hairs here, but the 4K or any other sampler re-sampling an SP will color that original sp sound that you may want to preserve. It's not gonna disappear, but it'll definately change. That dude is right on when he says that the sound also has to do with the outputs as well.
If I had a choice, I would DEFINATELY go to 2 inch tape for EVERYTHING, but it's too expensive for me right now. Now, I agree that the floppies disks are a problem. Floppies F up quicker than other medium, so if you can multitrack at home in a professional manner, do that when you done sequencing. This will archive your ish, hopefully with a backup of the sessions you made as well, and also save you from lugging the SP around to studios if you sell a beat.
There are alot of good arguments for the all-in-one approach, and there's no guarantee that having and SP makes you sound 'better'. What can I say? There's some cats out there who are knocking me out the box with just fruity loops, who never even seen an sp1200. Sometimes, making a symphony out of all kind of different machines happens to make me go that extra mile. Maybe it's placebo effect, but when I know that snare is comin out the SP1200, it makes me get into that mu'f#*ka that much more. Bottom line is, if you want speed, you gonna spend as much time resampling as you do saving to floppies and patching channels. It's all what makes you turn out the flyest ish. I feel like a 4000 with an SP1200 together is alotta firepower, and you gotta be feeling like you tha sh!t sittin behind all that.

when talking about the SP1200 sound its important to relize the "analouge feel" factor wich is pretty much 50% of the hyped(don't mean it in a bad way) sound, the thing is it does have a white noise generator that's called a dither generator, all samplers have it and like trupro said its is a factory algorithm and it varries from samplers and brands, on the 1200 its in harmony with its 12bit resuloution, that and the analouge filters are what give the sp the magical/analouge feel/sound

why can't you reproduce that on the 4k?! well you can !!!

First: u need to understand this: the thing is if you'd sample the sp1200 hit you'd capture a perfect picture of that hit/sound and it will play that exact picture evertime! it will not sound like 1200 though

Why? it won't sound as fat and warm cos of the different a/d converters dither generator and filters, it will basicly just sound like a hit from a 1200, and like trupro said the mpc4ooo dither generator might clean up the sample a bit dunno on how releveant/audioable that is though

run it though some tube/lamp gear and even some compressoion and you can get it to b about just as warm/fat but it still won't quite have that feeling, tha's why multisamples/zones are so vital,

sample the hit serval times from the SP, pick a few version that differ a bit and layer them with different zone modulation (u set it up, velocity random lfo whatever) so each time you hit/play the pad it will play a diffrent picture of the sp1200 hit running through some lamps nice board good eq, and your getting there,..

so that's the catch you want that sound you eather have to spend 1200bucks on a SP or 1200bucks on outboard gear,

now if u have a both SP and fancy outboard gear .. well then nothing can touch you, your on top of the world arn't u..

to answear it simply: nothing can sound 100% quite like a TR808 or a SP1200 but if you can get damm close or even better(?) my multisampled 96k/24bit TR808 HHats sound quite authenitik to me so authentik that I would have said that's an 808 if the 4k wasn't in front of me, they are so bright and sharp too I could say I prefer them over the orginal furrier and thicker sound (c how the 4k impacts the highs went from furry to sharp), and I've never heard a sampled 808 kit that I actually though was authentik before, so I guess its all possible to some exstent

I have read thru various parts of the 4000 manual and found very little. No surprise there. Apparently the MPC upconverts incoming signals of less than 16 bit to 16 or 24 bit.

So now we have a new wanted feature The ability to Sample an external source at it's native bit depth.

I have also tried to Resample and change the Bit depth of sample from 16 bit to 8 bit and 10 bit with no change. So the MPC fails to change to lower bit rate.

not *trying* to argue here (hehe all in good spirit, no "beef" ;) ) BUT:

IF you sample the outs of a sp1200 you basically sample its sound. Meaning, you're gonna capture the sound of that machines DA and (AD) and all the processing the sample went through before it reached the sp1200's outs (icluding dithering and any type of algorithms and filters and... etc.). Meaning theres no way the 4000 can clean an sampled 12 bit file into a 16/24 bit sample. Of course the 4000 samples either 16/24 but the sound is already processed before this. Anyone trying to say its not, can basically also say "if you sample a drumhit with added reverb on it the 4000 is gonna clean out the reverb". Its just not true and I dont see how you can argue with this.

However, the 4000 may color it with its own sound, although its supposedly very transparent (havent really made any hardcore tests myself) but it still will end up sounded ALOT like the sp1200. The only thing that basically could be any different (besides 5% of the sound) is IF the output of the sp1200 changes just like old analogue gear because of the transistors and consenders that were used back then. If that's what you people are saying then I can accept that, but ultimately, that means that one (like someone mentioned) could use a snare thats been "processed" through the sp1200 and have say, 4 versions of it (just sample 4 different hits with the same sound) and use them randomly, and get the sp1200 sound. Or atleast close enough so that none of us could point out what is the sp1200 and the 4000 in a blind test. Right?

what up Kalei, reread the last 2 posts again.

Its all there holmes.... :lol:
then reread your post.....

YES!!!!!!!!!!

NOOOOOOO!!!!!!! it will be 12bit until its recorded into the 4000 and then the sample rates and characteristics of the sound changes also..........


"..Apparently the MPC upconverts incoming signals of less than 16 bit to 16 or 24 bit..."

BEEP *wrong answer*, hehe, sorry, I read it and I do understand what you all are saying, however you should probably re-read my post as you obviously failed to get it.

Even it the 4k samples 16/24 bit the source was 12 bit. Right? And since you SAMPLE the outs, you get the 12 bit sound, right? Your not loading the samples in the 4k from floppies or similar, which would bypass the DA conversion, and THAT would mean you wouldnt get the 12 bit DA sound from it. I NEVER claimed the 4000 keeps the sample in 12 bit, if you think that then re-read the posts.
