I'm using 2 delta 1010's in a 2.4 pentium 4 w a 40 gig system drive, a 160gig storage drive, and a 100 gig tracking drive (record destination) and a radeon 9000 video card with vegas 5.0a. During playback, it works great but if while recording I zoom in or out or scroll on the scroll bar, it causes glitches and pops and skips and the occasional crash. Sometimes it even happens when I don't scroll or zoom.i'm using asio w input monitor on. I found that if I moved the project to the drive on ide 2- 2nd position there is less of this. If I record to the drive on ide 2- 1st position it's really bad and if I record to the local disc it's very minimal but still there. What could this be? Anyone else having this problem or possibly solved this prob. in the past? The project I'm recording on has about 14 tracks mixed for playback and happens no matter how many tracks are armed for record.It doesn't happen with sound mapper or wave driver. Just asio. If anyone can help it would be appreciated!!
