NI synths eating up CPU...?

I'm running FL 5 studio, and in my current project, I have 4 Native Instuments VST's running, and my CPU limit is hitting like 26%. During playback, there's a lot of static type sounds that come in and distort the hell out of the sound. I have a Sony Vaio desktop that has 1 GB ram...is it possible that those 4 VST's are really using up that much CPU?

yep, NI synths are greedy mo fo's.
Reaktor can be quite bad

ahhh, figured as much. I have 1GB memory now...I guess it makes sense to beef that up a bit. Is installing more memory a difficult process?

No, it's not. Try not to touch any of the electronic components, just handle the green part. If it's DDR memory, make sure you install it the right way, one side has more pins than the other. If you do it wrong, you might flip a voltage pin up and short your board, your memory, and your power supply.

Other than that, it's really easy.

I have a celeron 2.2, 512ram using fl studio 5 and NI, dont really have anyproblems, its probably not your ram or cpu, probably underruns on your sound card, turn up your latency on your sound card.


I have 2 instances of reaktor and 2 instances of Ni-Pro 53, runs at like 47% cpu I know I had to turn up my latency settings within fl studio to stop it from making a crackle sound.

yes I noticed it, Reaktor only can take up more as 55% of my cpu (2600mhz)

It eats my cpu too.... especially reaktor

it depends on which synths. i consider fm7 and pro53 to be ones of the most efficient synths out there in the vst universe. battery 2 can be a cpu hog sometimes, and reaktor can eat up a cpu in the blink of an eye. consider increasing your buffer size a bit.

Reaktor 5 is even worse!

Mine makes a crackling sound, when you say turn up the latency, do you mean increase or decrease the size of the buffer?

I can sometimes decrease the buffersize and the crackling goes away

up the buffer, stick polling + hardware buffer on

ive only got 512mb ram and get by, just lol. the hardware soundcard gets an extra 10% worth of cpu or so for you to play with if you fancy upgrading there

you can always bounce the track to wave and import which reduces the cpu a lot if the instrument has a high polyphony

have you done the performance tweaks listed on http://www.blackvper.com/ ? They can free up a good bit of CPU that XP is unnecessarily hogging by default. Make sure you get rid of anything that is always running that can be manually started later (a cluttered deskbar tray with tons of icons is a good visual indicator that tons of stuff is running).

hey thanks guys. I moved teh buffer all the way to the right and its working perfectly now.

For the last few weeks I've been getting a bit worried as to why Ableton live was overloading all the time whilst only running a few NI vst's.
Just realsied I've had my sample rate set to 96000k for the last few months.

Doh!

I was just about to post a thread on this. Sory to highjsck but i only need one answer and i can tell id get flamed by opening another one Ive got myself a 3.2ghz with 512 ram (need mroe i know) and i NEVER thought id ever use my cpu limit with reason, but low and behold after a mixing and mastering session with my lecuturer today, ive put eq and compression....well on everything lol. n now i cant even play just the percs bassline and lead without it crying at me.

so what can i do with this? literally export some of the channels (like percs im using, considering im using over 2 full Rerum units with every instrument alocated its own EQ unit and compression unit) and import them as samples? Its obviously do-able but sounds like it could cause a few problems, anyone have any ideas or techniques that could help? Thanks

So have i. Whats wrong with that?

Hey. In my honest opinion, you really shouldnt need to compress everythign individually. The only things that truely need to be compressed are instruments that make the mix muddy, like swing basslines, long basslines and kicks and some other percussive sounds. Youll get a much better mix of your song by doing this and then appyling a single compressor over the entire track. This will clean things up emensely(sp?) while loosening the rope around your cpu.

In answer to you setting your sample rate to 96kHz: Theres one important piece of information you need to provide us with to make a clear judgement on if its ok for you to have it set at 96kHz or not, the type of sound card you have. If you have a newer Audigy (Audigy 2 or above) then you are probably ok. If you have some type of professional sound card, you are most definantly ok. If you arent using either of those, then you are in trouble . To give a clear impression of what goes on with sample rates, you need to think about digital pictures, thumbnails, wallpapers, whatever. Think about blowing up a picture only to find it loses its detail in graininess and realizing its completely pointless to blow that picture up that big because the detail isnt there. Appyling this to sample rates and sound, its the exact same deal. Unfortunately, if you dont have a card that handles onboard upsampling, then you're forcing your processor to do a lot of extra work for quality you arent going to be able to hear out of your sound card, nor on a cd. The only good reason really to use 96kHz, is if you are planning to make a lo-fi DVD-Audio disc or lo-fi Super Audio CD. Turn it down to 44.1kHz and I'm willing to bet that youll see a performance jump .

Hope this helped.

Cheers,
Zac

you have put an eq and compressor on EVERYTHING? damn. why? you put those if you need them, and you judge that by your ear, not because someone tells you "that's the way pros do it". i am sure you do not need compressor on EVERYTHING. what should you do? the easiest thing to do is to find sounds you do not need to mangle with. the result of that is the most natural sound you can get. many musicians just choose instruments which have their own frequency range, and use playing techniques which make compressors unnecessary.

also, 96 khz sampling rate is killing you. with 48 khz you will literally halve the processor power needed for your projects. it is best to work in 44.1 and then possibly render in 96 khz. also, try increasing buffer size.

Just to butt in- you guys keep saying how much CPU things are using - how can you tell??
Im using Cubase Sx - is there something I click to show me how much each Vst is using??

Or is it something in my control panel?

Im using an Audiophile 24/96 if that helps. Why did i compress everything? well im kinda new to the compressing stage, i know the basics but its stil la bit confusing so im only really experimenting, my kick sounds amazing now tho i notised the 96 is killin the cpu when i put the sample rate down to 44.1. But it didnt sound as nice
