Previously recorded tracks recording onto new tracks?

Wow, you have a lot going on there and further complicated by using your onboard sound... which you probably don't need to do to get the results you want.

The Monitor Mix knob selects whether you hear in headphones, or through the Line Out, either whatever is coming in the Input (direct) or what is coming into the USB connection (Playback) or any blend of the two. The reason for the direct sound is so you can hear what is being recorded without having to listen to it through the software, which may have a lot of latency (delay) in it. If you were recording a vocal and the latency was throwing you off you could disable the input echo on the track you're recording on and mix in the direct sound of your voice as it sounds at the Lexicon input.

It might help if you could describe the way you have everything hooked up in detail.

Not to continue to beat a dead horse, but these guys are right.  use ASIO mode and it will only allow you to use the lambda, it won't allow you to use the realtek in that mode.  then plug your speakers and/or headphones up to the lambda and use it ONLY.

Before we go any further, if you are only seeing the Left channel of your Lexicon Lambda then there is something wrong with your drivers, the way they are installed, or the way Cakewalk is recognizing them. I suggest you reinstall the drivers for your device very carefully before you do anything else. Turn your computer off, disconnect the audio interface, turn on the computer then run the driver installation program. Don't plug in the Lambda until you are prompted to do so.


Then I suggest you go into your Sonar Home Studio 7 Audio Options and change the driver mode to WDM/KS and run the wave profiler. If you can post screencaps of what you see in each tab of your audio options it would help a lot to understand your situation.

Where are your speakers connected? The line out of the Lambda?

Thanks for the responses, guys!

I have done as you both suggested.  Shut down the computer, unplugged the Lambda, and booted up.  Downloaded the 2.5.0 version (only one there) of Lambda Installer from Lexicon's Web site, and ran it; connecting the Lambda when prompted.  Went into HS7XL and changed the drivers to WDM/KS and ran the wave profiler.  I have attached screenshots of the four tabs of Audio Options that resulted.  (Super post in the sticky section on how to attach the screenshots, I hope I got it right.)  Have done nothing else.

Speakers are accessed by the Labmda rear Line Out jacks into a stereo receiver's AUX jacks.  I disconnected those connections for this troubleshooting exercise to minimize the number of devices & connections in the mix.
 
Again, thanks for all your patience and assistance!

on screen 2 - uncheck all the boxes that have anything to do with the realtek.

Beagle


great minds! 

but I don't think you should run the wave profiler again after unchecking the realtek - running it again will probably check those boxes again for you and even if it doesn't, running the wave profiler after unchecking those boxes is uneccessary.

I disagree. I think that the wave profiler finds a profile that all enabled drivers can support. Disabling the Realtek will allow the wave profiler to find the best settings that the Lambda can support, such as a higher sampling rate and bit depth, Running the wave profiler shouldn't re-enable the realtek drivers. It doesn't when I do it.

Thanks again, guys, for your help!  I tried your suggestions, and...

Results: Unchecked the Realtek boxes, hit the Apply button.  Now, the only things checked are the USB Audio devices.  Tried recording, same results as before.  Then ran wave profiler.  It only profiled the USB Audio device, Realtek boxes remained unchecked.  Tried recording, same result.  Input for tracks was Left USB Audio Device and Right USB Audio Device; output for both tracks was USB Audio Device - the only choice.

So, at this point, I decided to try something different.  I opened Cubase 4 LE, which came with the Lambda.  I listened to a Cubase project I recorded earlier with one guitar track and two vocal tracks.  There was no bleedover between tracks.  So, I recorded a new two track project with Cubase, and the bleedover problem now shows up there. 

My thoughts at this point are: This setup used to work properly, with Cubase.  Now it does not work with either program.  Something has obviously changed.  Since I reinstalled the Lambda drivers last night, I'm thinking maybe they are not the issue.  I have installed a few Windows updates since Cubase worked, but no major ones; no SP's or anything.  So I don't think it's Windows, but I'm certainly no Windows expert.  That leaves the Lambda hardware itself.  Not sure what I can do with that... 

Some next steps I have thought about are: 1) Setting Windows back to a recovery point when I recorded the "good" Cubase projects.  2) Disabling the Realtek junk in the BIOS to see if that changes anything.  3) Installing the Lambda on a different computer, and try either Cubase or HS7XL.  The fact that Cubase now behaves the same way HS7XL does would seem to eliminate HS7XL as having a part in the issue.  Since this is a Cakewalk forum, I don't want to clutter it up with non-Cakewalk issues.  So maybe I'll go away for a while, and try some things, and let you know where I end up.  However, if you have ideas you think might help, and you don't mind extending this thread, I would be happy to hear them.  Whatever happens, thank you for all your responses, I really appreciate your ideas, suggestions, etc.  

I'm 99% sure it's not windows or microsoft updates. if it's happening in both cakewalk and cubase, then the problem is with the lambda.

I 2nd that statement. Its a property in your sound card
