When I'm working on a big project , a lot of cpu consuming I have to increase my buffer size to 2048 or 4096 samples but that increases the latency as well and I can't compose anything in midi anymore or even all the midi I already have doesn't play on time(when I increase the buffer size to more than 1028 to avoid sound clips and stuff).
I believe this should the a common problem, how u guys manage that?
I'm running p4, 1.5 gigs ram, xp sp 2, mbox1 and cubase sx3.1 |

Oh, really hate these kind of problems.
My advice is to try some different setups. I don't know how well the latency is on the MBox, but I assume you're running the ASIO-driver..
In Cubase you can control the internal Buffersize of Cubase (Well, atleast you could in version 1, I don't really know if you can in version 3.1 since I haven't had any timing and click-problems with 3.1), you do it in the Device Setup> VST Multitrack as far I remember.
If nothing works then try to use a different driver than the ASIO, try ANYTHING, my experience is that "similar-looking" PC's (Computers with nearly the same specs) can act VERY different..
Good luck.

I can't find the option to lower the latency, when I set for 1024, cubase already give a latency time;
in - 82 ms
out - 58 ms
If I raise the buffer up again the latency will be even higher...
I believe the mbox1 can only work with their asio drive, right? |

I usually start dropping alot of things to audio. At this point when have to raise my buffers to get the sound to play, I have enough really good parts I want to keep that I can drop a bunch to audio. I then turn off all the synths that I'm not using, but keep them there in case I want to go in and change a part and re-record it.
This is the best way I've figured out how to do it. |

Yearh, that's right.
I think I have to do this with my new track because of the limited amount of resource in my new UAD-1 card, when you start to use it, you just can't get enough, but the card seems to have a limit, hehe.. :/

Upgrade your CPU or start bouncing your midi tracks to audio as soon as you get the first clicks and cracles. |

How do you like the UAD-1 card? I've been really contemplating getting one. It'd be nice to have something else help manage some of the recources like that. |

I am TOTALLY satisfied with the sound of the effects. They really have a warm feeling and adds an extra dimension to the sound (Especially when you think of them compared to the standard Cubase SX3-effects).
The only thing that's "bad" about it, is that when you've firstly used it on a synth or bass, you have to put similar effects on similar things in the track, to get the overall sound the same. If you just boost the bass (In my case Albino) you don't have to do much more, but as soon as you start to use the standard Realverb-Pro reverb on the synths, then you can't run e.g. Vanguards own reverb, as I earlier have done..
Another thing about the uad-1 card is that it gets pretty hot, as it is "only" passive cooled. I've set a cooler under the socket that pulls the air out of the PC, and this has helped a fine bit concerning the temperature of the card.
I have a link to a similar cooler (although the link is of a 2-socketed cooler and has some extra features):
http://www.getmore.dk/templates/imw-product.asp?ProductGuid=761345%2D77194%2D8&GroupGuid=3520&SelectedGroup=3520
(Sorry, I only have a danish link)
So if you fall in love with the sound (Which you will ), then watch out and don't use the DSP's full power right from the start..

hehe, great thank you for all the information. It's always best to hear from someone who actually has some experience with it. I'll make sure to save some DSP for the final mix  once I get one.
That fan also looks like a good idea to stick next to the card, from the looks it only takes up 2 spaces as well. |

Yes, it takes up 2 slots, the one I use atm is a "1-slot".
Another issue concerning heat is to give as much space to the different cards you have in your PC.
For example, if you have a PCI soundcard, PCI DSP-card (The Uad-1) and then an AGP graphics-card, then make sure to have at least 2 slots free space from the AGP-card to the DSP-card, and then 2 slots free space from the DSP-card to the soundcard.
I see that this can be an issue for people that will buy the new UAD-1e PCI-Express card, because of most new graphicscards also run from PCI-Express, but one rule is definetily clear: DONT PLACE DSP AND GRAPHICSCARD SIDE BY SIDE.

hmmm thats quite a few slots, you'd have to make sure to have a huge case for that. Like giant server style thermaltake case or something. Either way it's a good suggestion. I have a Thermaltake that has 7 cooling fans in it so I think it should be able to handle it. |

Gah that case looks like a spaceship of plastic  
Watercooling is the way to go |

haha, well maybe you aren't thinking of the same one, because the one I have is all made of metal, but if you are no big deal it's what I have to work with so I do my best with it.
I would prefer water cooling I guess but I can't afford to make big changes with my set up like that right now. Maybe in the future some day. Right now I just need to make music, not keep changing everything in my setup. |

Hm, strange... i never noticed any heat-problems with my UAD-1 card. And i only use one case-fan at the bottom of my DAW.
