I am moving into the digital domain and have encountered a problem.
I know it is going to be a simple fix, and once I figure it out I will have to smack myself for being so dense...but anyway

Here's my slightly outdated setup and the issue

Lexicon Core 2 (wish I knew then what I know now)
VM200
Cubase 3.7

I have been running my set-up using the analog ins and outs with no problems... Digital outs 1 and 2work as well (with rebirth and as the outs for playback)
Now the problem I am having is that I can't get the ADAT ins to work. Is it a word clock issue? I have the core2 set to WC RCA
and the VM200 set to INT44. I have a cable running from the RCA word in on the core2 to the VM200 with a nice adapter on an RCA plug to make it work. Now when I activate the channels in Cubase and try to record all I get is static.

What am I doing wrong...any sort of checklist I should run through to get this working?
Thanks

If you're making an analog transfer (and if you're using the RCAs, it is an analog transfer) you want the clock to be set to internal. If you were making a digital transfer via lightpipe, you'd set the clock to ADAT optical.
 
Do you have your VST device\inputs set correctly? Do you get any levels at all in the VST mixer when the "In" channel buttons are activitate?

word clock doesn't have anything to do with getting an audio signal from the VM200 to the Core2.

As far as WC is concerned, I'd set the PC as the master and the VM200 following the PC clock.
 
Thanks for your help...
Here's the deal
I am trying to do a digital transfer.
The Core2 has a RCA S/PDIF input on the front that doubles as a Word Clock In...from what I can tell the S/PDIF out won't work as a Word Clock out, so I can't set the PC as master.
The cannels in Cubase can be selected, but all I get when I record from them is static...so my assumption is that they are selected properly, but that somewhere else in the chain I am losing the signal...If they were not working at all I would get no sound at all or is my assumption incorrect?
The analog inputs and outputs work....the digital outs work...just nothing from the digital ins.

Maybe I am just missing something in Cubase or the VM200
I'll keep trying, cause I really would like to be able to use the mixer the way it is intended.
I might try and set the PC as master for the clock and test to see if it can send WC over the lightpipe.
Next step is to tear apart the setup so I can try a different cable
I guess it is just trial and error.
thanks again for your help and let me know if you have anymore ideas.
 
Do you have your signals routed properly on the VM200?

Go to the routing/phasing menu and check.
 
Maybe I'm missing something here. If you're going from the RCAs on the ADAT, you CAN"T make a digital transfere. The RCA outs on the ADAT are ANALOG only. Now if your card has an optical input, you may still not be able the make a digital transfer as ADAT optical and S/PDIF are two different formats.
 
Track Rat-

The card has Adat in and Adat out (optical connection)

It has RCA S/PDIF in and out, but the RCA in doubles as Word Clock.

So it is a digital connection from the ADAT out on the VM200 to the ADAT in on the Core2 via optical cable...

I have a seperate RCA cable running from the Core2 Word in to the VM200's Word out (with an adapter) with the VM200 set as the master.

Sync issues have always been daunting to me, so I guess that is why I automatically assume that it is the root of my problem.
(It took me along time to get my midi gear to sync...and I still have problems with it once in awhile)

What else could it be besides the Word Clock?(I haven't had time in the last 24 hrs to sit in front of the problem, but I am pretty sure I routed the channels correctly, I will try it again.)

Thanks for the quick replies and all the help
 
Unless you have a BRC on the ADATs you can't use word clock. Set the clock in the computer to ADAT optical and the card will clock to the incoming enbeded clock info in the audio from the ADAT.
 
The Core 2 gets very unhappy when it isn't set as the master. Unhook the s/pdif, set the Core 2 as the master (internal clock) in your lexpanel. Make sure the ADAT channels are enabled in lexpanel. Set the VM200 digital clock to external, make sure the sample rates match on the VM200 and the Core 2 (44.1 or 48khz) after making the changes in lexpanel, you'll probably have to reboot everything (at least once) :) Transfer your stuff.

See if that works for you.

Ah, the old Core 2. Good luck! :D
 
It works!
Thanks for the help...
I set the Core2 as the master and had the VM200 set to recieve WC through the lightpipe and after 3 reboots a couple weird crackles and pops it is now working.
Of course I know how infamous the Core2 is so I will probably have to go through it all again once I scrape together the cash for a new card and a software update.

I will have to come to these forums for help more often...might save me some headaches

thanks again

:D

Glad we could help.

I fought with the Core 2 for over a year and couldn't get it to run as stable as I wanted. I had the mp 100 also. I loved the sound of the card, but the drivers were garbage. I decided to go the lightpipe route to see if things would run smoother, but alas, no go. Once the definite word was given that Lexicon would not be releasing any more driver updates, it was e-bay bound.

Good luck.
 
A success story

Yo Chopper, Still using the core2?

Yes, I just recorded my 17th CD on this unit so far. I still use a
Pentium II 350, but have upgraded my motherboard from the BX style to an Asus P3c(Intel chipset).

This new motherboard has much better bandwidth for the AGP, and I have fewer crashes. It will also allow me to upgrade my CPU to a PIII when I'm ready. I have not yet lost any recorded material in the crashes, since Cool Edit has a great crash recovery system.

As bandwidths and speeds increase, the bx chipset boards are getting close to being obsolete, since they have limited track counts. I still use BX440 boards in 2 of my audio computers, one to mix protools(LE has only 24 tracks max), and one that I run: Acid,Rebirth,Reason,and other sampler type programs for our DJ's to use for beats.

Unfortunately, most of the users on the technical help sites have only recorded 2 or 3 simultaneous tracks. So they usually don't encounter the problems of bandwidth and speed that high track counts cause. I've been fighting these limitations for a few years now.

Hey man, is this the same Chopper that hung around the old ezboard Core 2 site? If so, I got a lot of good info from you when I had my Core 2.

The card never played well with my AMD setup, though I was finally able to get 6 simultaneous tracks (without pops and clicks)in by setting my Samplitude recording buffers as high as they would go. :eek:

Too bad, I really liked the sound of that card.
 
The quote is from him.

I posted it to give some people hope and guidence.
