Hi!
I am using a SoundBlaster Live! (emu10k1) card, with the kX drivers. Audio played directly to the kx outs (Front l/r in the Epilog)) works just fine, as does audio from AC97 (in kx, this is Prolog hooked diret to Epilog output).

The problems begin when I try use some of the internal routings, Im not sure of the exact terminology, sorry, but I route the audio around in kx DSP like this: I want to send audio (AC97, or winamp) to ASIO 0/1 so they come back in the 0/1 channels of the FXBus. This is wired direct to the Epilog output. It works for a short while, and then slows down, tears and becomes utterly mangled. It'll make horrid noise for a minute, and then possibly 'clear up' and break up again after another minute or so....

I have reinstalled several different versions of kX, and have tested this with Cubase SX and Ableton Live 4. I'm fairly sure the problem lies in how the audio going into the Epilogs asio inputs gets treated, before it reappears at the FXBus.

I'm going to move the card around, in the hope the problem goes away, but I'd really like to know if anyone can recommend anything before I go and try reinstalling windows and all the software!

Nobody at the kx project had any ideas? I've never used the kx (yet - until it supports the E-mu 1616), but like the idea of it.

If the "FXBus" shows up as another ASIO device (to your software), this adds load to you PCI bus, and the addition might be enough to cause the drop-outs. Try setting the ASIO buffer size a little bigger, and see if it helps. (also, are you running 44.1kHz, or 48?). Otherwise, if everything is *internal* to the 10k1, then it sounds to me like a kX/DSP issue?

Also: Video Card Owners (ie - nearly everyone), I just learned a new trick last night: if you're video card has large amounts of video ram, but you don't run big games or anything that will ever USE that much ram, then set (in your bios) the AGP window to be 1/2 the size of your video cards ram. It helps improve the performance of your system. From what I understand, it reduces the time the AGP card spends with it's driver running on your CPU.
