Hi, I'm playing a Direct Sound Secondary Buffer on my sound card. I'd

now like to apply effects to this buffer and control these effects in

real-time using sliders. The problem is that SetFX only works on

non-playing buffers-

I have tried stopping the buffer, changing the effect, and then playing

the buffer again, but I get glitches when I do so. Even if I comment

out the setFX function I still get glitches. How should I be doing

this? Thanks for your help, Barry.
