Hi, I'm new to the forum, but have been recording for a while. I recently had a few issues with my PC, i got a new soundcard, and had to rebuild the whole thing. My set up is a Roland VSR880 connected to a VM3100 pro. My soundcard is a Guillemot ISIS, and I'm using the SP/DIF input. I have a Pentium 4 PC, with 512 MB DDR ram, and my programs are loaded on a 40 gig drive, and i have a seperate 100 gig drive that I record onto. the program i am using to do the mixing/mastering on is Vegas Video 3.0, which is by sonic foundry My problem is that when I bounce my tracks to the PC from the VSR, they seem to record OK, but then when playing them back they have a funny clicking sound in them, every second or so (but not regularly). The tracks are Synced via midi, and i have checked the frame rates are the same, (25 FPS), and even tried using 30 fps. The tracks sound ok if i open them in soundforge, and don't have the click, but Vegas video won't play them properly. Any help on this problem would be great. Thanks, and i look forward to being a member of the forum.
