Ok so is their any tips for limiting CPU usage? Im not sure if its my PC setup or if I missed something setting up cubase.
Im using Vangaurd right now and I only have one small riff down and its using a little less than half my CPU power and Im getting small clicking sounds while I playback the automation.
I wouldnt say my computer set up is all that bad. I may need to up the RAM to 2 gigs. What do you guys think? All help is appreciated.
PC Setup:
Asus p4p800-E deluxe motherboard
2.8Ghz Pentium 4 processor
1GB Kingston Hyper X PC3200
Radeon 9600 graphics card
E-mu 1820 soundcard/interface

what latency have you set in your soundcard's control panel? probably you need to relax this setting a bit.
 $ exp(j*pi) + 1 = 0. $ |

Yes, the clicking is almost certainly the Latency setting on your soundcard/ASIO driver. Er, assuming you have an ASIO driver. If you don't, you definitely neeed to increase the latency setting even more in that case.
As far as Vangaurd goes, check the "voices" bit on the bottom right of the instrument and lower that. Some patches have it up at like 32 voices for some reason when you only need between 2-4.
I had a similar problem there, I had a machine with the same specs maxing out the CPU with only the Vangaurd playing, turns out the Voices setting had gotten jacked up to like 64 or something absurd.

I have an emu0404 - and the only synth that I get this with is the Stylus RMX. Setting the latency to a lower value (<10ms) sorted that out for me. |

Ok so I originally had my latency set at 2 cause I thought the lower the better. But I upped it to 10 and the clicking stopped. Also lowering the voice amount in vangaurd helped alot too with CPU usage. Thanks a bunch guys. |

Well, depends what you mean by "better".
The lower the latency, the less delay there is going to be between when a MIDI signal is sent and when a sound is created by your computer.
Since most people play along with tracks with a keyboard, they want the computer to play as close to "real time" as possible, but the lower the latency, the harder your computer has to work. When you have latency too low you are overdriving the capability of your sound device and you get the clicking.
2ms is insanely low latency, 10ms is good. Most non-ASIO soundcards can't manage less than 100 wihtout pops and clicks. At latency this high there is a pronounced, noticible delay from when you hit a note on a keyboard to when you hear a sound.
If you're not playing melodies or capturing drum patterns with a midi controller, having lower latency isn't as important.

jep! as a guide
1) set low latency around 5ms (or up to 10ms, depending on card/machine) when you're playing along (or using your machine as a 'synth' in a concert)
2) set higher latency when you're in the mixing stage

Vanguard is a CPU hog when you have it set to use a lot of voices, and then you also use a lot of polyphony. Reduce voices, reduce polyphony, up your buffers/latency, upgrade your computer, use SX3 freeze if you have SX3, or export the track to audio. |

I've always thought Freeze was pretty much worthless. It takes the same amount of time as actually bouncing the track, but doesn't save nearly as much CPU as a bounce and then turning off the VST.
Also once something is bounced you are more likely to start directly editing the bounced audio, cutting it up, applying offline FX, etc. Offline FX onto audio is really the key to getting a more diverse sound with a bigger variety of interesting things going on.

I agree, some people like it tho. It was pathetic in SX1 and SX2. In SX3 it is only slightly pathetic.

Absolutely, the more you can work in audio, the better. Steinberg claims that PDC is sample accurate, but that is only partially true, I still see latencies/gaps when I bounce stuff, and end up lining up wav files and ctrl-alt dragging audio back to zero. Nothing is as tight as audio. PDC is close and sometimes perfect, but not always, particularly with PCI daughterboards. |

Funny thing is, UAD-1 has a "Limit CPU Load" checkbox in its configuration menu, which prevents your system from loading new plugins when its CPU is too close to being taxed. So it's no joke. 
Prevents crashes. Wonder why we can't have this in other stuff?
Also I forgot to mention, SX3 freeze doesn't work on Vanguard apparently, because it's a real-time export plugin. |

i can agree on that with tomos!
my core 2duo e6600 works super its the first cpu i havent maxed out yet! maximum usage ive seen so far is 50% on 1 core only!
imagine my older dual core cpu p4d830 in 3.0ghz was maxed in most of the projects and i had to overclock to 3,8ghz to be able to finishe them! E6600 is 2,4ghz!
intel did a great job in a great price!
