I've just moved to a new computer running Win7. Bought an Alesis IO|2 since my old fireware interface wasn't supported any more. And had to upgrade to SONAR X1 Producer.
I don't remember having any issue before with input levels but they're my source of pain today.
I'm using the IO|2 in MME driver mode as recommended by Cakewalk. When I set the input level appropriately on the IO|2 so its built in meter is staying in the high green, I got horribly distorted output in SONAR so I went looking for input trim.
Everytually right clicked on the volume control icon, selected Recording Devices --> IO|2 --> Levels and had to set it to about 1 to get a low distortion input. But I'm getting a background high pitched sound that's gating with the level of the input which makes me think levels are drastically off and having to 1 out of 100 also makes me think I've got a gain-staging issue.
I read through this whole thread and never got a clear understanding of the digital signal path from the interface to SONAR.
Any tips on using the IO|2 and setting input levels? The IO|2 also seems prone to drop-outs which I never had before. CPU usage is super low on a project with just some straight audio tracks. Just buy a better interface?
Thanks,
