some of these may be a bit obvious but i'm just starting

I'm running cubase 5 on win 98ME, 1.3Ghz AMD TBird, 512Mb Ram with a SB Live card

Running the direct X full duplex driver I get a 46ms latency which is pretty good (I think) but sometimes it can be noticeable when using the automated mixing stuff. If, say, I get the volume on a channel to change at step X.x.x (as stated in the event list) the actual change in sound when the song plays through occurs noticeably later - I presume this is due to the latency. Is there any way I can automatically shift all the events for the automated consol back by that amount of latency (worked out in the step time format) so as to make the actual events occur in the correct place?

Also, does the latency affect only audio, or will it apply to midi input as well (i'm thinking of getting a midi keyboard), meaning that all midi input events recorded in realtime would have to be shifted back to account for this?

Thanks for any help.

I can't answer all those questions, but what I would suggest is going to the Soundblaster website and seeing if they have a dedicated ASIO driver for your soundcard. That will drastically cut down latency.

I run an Aardvark Q-10 and with it's dedicated driver my latency runs from 2 to 4 ms depending on what I make my settings.

Good luck.
 
APSLive drivers for SB Live

Creative don't supply ASIO drivers for the SB Live. someone on the board recommended "APS live" drivers, which are apparently non-official (non-creative) drivers that turn the SB Live into a full ASIO card. He gave me a link and i got the drivers, but I haven't used them yet, cos I'm scared :-). I don't know if the asio driver will still allow me to use all the general windows stuff like the media player etc properly, or whether it might just muck my system up. Does anyone know about these drivers, or use them, and do they cause problems for the system in general even if they do reduce Cubase latency?
 
Get a card with ASIO implementation eventually, if you plan on making this a serious hobby. Until then, latency will be an issue, and you'll have questions like these that are really tough to answer!

Also (ya, I know it isn't much help :p ), read up on latency in the documentation. I am pretty sure there is some solution to your problems. You can't get rid of latency but I am almost positive that there are settings that will take care of your dynamics and automation and make them operate in correct time.

Good luck!
 
SB Live can get to as low as 2.6ms latency if you use KXDrivers instead of the original Creative drivers...

here they are:

Keep in mind that you should make a little modification in the KXDSP section to enable ASIO recording. Also you should copy few DLL files to your Windows/System directory to enable the drivers. All instruction are avaliable on the site itself.
 
I know there's a checkbox somewhere in the audio window that allows you to do a global disable. I've used that and it works pretty damn good.
