multi-track recording delay apprx 500ms

Can anyone tell me why I get an approximately 500ms delay in multi-track recording?
Eg - I record one track, then another, then play them back.
The playback starts together then gradually develops a delay until settling on around ½ second delay.

I am using Sonar 6 Producer Edition (ver 6.2) on Win XP Pro with a PCI Soundblaster 24. I got USB Tascam US-122 sound box an’ it works fine, but I would like to get an 8-track PCI card and fear it won’t work!

Any help is greatly appreciated. I've looked everywhere - even the Microsoft support pages.

    I'd say you are experiencing timing drift since they start together and drift apart. Soundblasters are pretty famous for that when recording at 44.1KHz. They seem to do better at 44KHz. But then you have to convert to 44.1KHz to make a CD. Try 44KHz and see if you get better results.

    Hey guys, Also I tried an old Turtle Beach sound card which does the same thing (1/2 sec delay) , but which works fine on my old windows 98 machine. ???

    The issue with Soundblasters is likely OS dependent also. My cheapo Soundblaster worked fine with ProAudio9 on Win Me but gave me the timing drift problems with PA9 on WinXP. It had fine timing at 44KHz on WinXP.

    Try a sampling rate of 48k, that has solved the problem for a lot of folks.

    Also do a internet search for ASIO4all, that driver will lesson latency for a SB (although your main problem is not latency it's that SB doesn't work properly at 44.1K sampling rate.)

    Yes, fep is right about the working sampling rate. It's 48K, not 44K like I said in my posts.
