Hi, I have a SB16 nicely configure with everything working fine. I just noticed in earlier posts that peole with a similiar card had other sysnthesizer options turned on. The modules they are loading which I haven't compiled are: mpu_io op13 What would I turn and and where to get these? I assume theese are the synthesizer modules? Thanks Jonathan -- "Hey, I think I finally got the hang of i-"
