(one cool ) have ??'s set-up.two internal sound cards,one usb sound dogle supplied with H 6/7..info--have used internal as master (creative sound blaster), used USB SD as monitor.. use it on weak program (ZULU D J) notice that monitoring lagges behind master,starts same but has time lag as plays(in relation to the master),Tried same exp on VDJ demo, Noticed difference in time from master compared to monitor,is this inherent to just trying to use the computer only and two seperate S C ,and is rectified by the multi channell S C,, or is it not noticed because the outboard mixer cue (Monitoring) aspect is used :cool:

has any one come across this??

A multi-channel soundcard should remedy the problem, as the single USB dongles don't do anything as far as performance is concerned.

I dont think performance is the issue, havent got to try it on Cross, never tried to install asio 4all, ,its similiar too if you have two tv 's in seperate rooms playing the same channel and you can hear a lag or akin to an echo effect,think its might have some thing to do with to seperate audio cards??,,,if i kinda understand how the siginal are sent to the u??// sound card maybe thats the difference because you are monitoring from one souce??? :confused:

may be getting a good monitoring source is not possible with two seperate sc??? :confused:

The sound card i have internal is sound blaster platium fatility, has 7.1 surround, never tried to set up the monitoring section off of the other channeles,,not trying to change anything just trying to understand why i am hearing what i an hearing :cool:

Could be due to limitations of DirectX ?

Very true!

info on direct x and its limitations, have you experenced the time lag in using two sound cards??? :cool:

Ive tried it on 2 internal SC before Dan. When i had some gaming 3d sound card and a creative both installed, and the creative was always a little laggy compared to the gaming card i had at the time (2006 ish, desktop PC). Coulda been the PC had something to do with it- cant remember the specs on it; oh and the gaming card had a bit more output level too.

gentel men thans for the info :cool:

maybe one of the software engeneers has a little more insight and can mabe take the time to explain the problem i an expericing :cool:

i think it might be a inherrinert flaw with the possibility of using a computer to send two signal to two different sound engines and not have the time lag in sound, that is probly why the monitoring is done from the single sound card ,like its done on a multi channel mixer :cool:

when using the two sound card set up on what i thought was/is a weaker program(zulu DJ) i experinced a creeping time lag from the out put of the comp by the output of the second sound card,resetable by toggling on/off the monitor :cool:

on vdj there was just the time lag(like explained in above post) :cool:

Let me try to explain... There aren't many way to use sound cards under windows.
With 2 sound cards if their clocks are different then there is a lag. Whatever it's under DirectX or Kernel mode.
With multichannel sound cards as a 7.1 you can use up to three stereo channels without lags as there is only one clock. Problem, for cd control or vinyl control it use too much latency.
With one Asio Sound card (one clock whatever the nb of inputs/outputs)
Using Asio4all you can use 2 or more sound cards together with a low latency but of course you need a software with Asio sound options. You keep of course the lag due if different clocks.

thanks unc :biggrin:

explains a lot :cool:

so my next statment might ring true :?:

due to the above mentioned difference in the two sound cards you will always have the time lag :?:

sooo even if mixvibes changed the set up of the monitoring you would still have the problem of the time lag and not be able to discern the true postion (by hearing) and have the mix in sync because of the time lag of what you are hearing in the monitor not actualy being where the music is :?:

It might be the case with different sound cards.
