Beginner Question

gberchin · Feb 26, 2004, 05:46 PM

Please forgive me for a question that probably has an obvious answer, but I have waded through so much documentation in the past couple of days that I am just confused and frustrated.

I am not a complete beginner at development under ASIO -- I have developed one application that runs on an ST Audio DSP24 card. Now my customer wants me to port it to a SoundBlaster Audigy 2 ZS. Porting the code was pretty easy, but no matter what I try, I cannot get the card to send MY data out the audio jacks on the back of the card, instead of the audio that IT creates in the onboard processor. Creative technical support sent me to the kX Project site as a possible solution to my problem, because they think that their ASIO drivers are not capable of doing what I want.

So, my question is: Using the kX ASIO drivers, can I receive data from the "CD Digital" input on the Audigy 2 ZS card, send it to the CPU via ASIO inputs, process the data in the CPU, and send the resulting data via ASIO outputs to the three physical output jacks on the back of the card? I don't care that the input data are resampled to 48 kHz. I don't care that my latency may be a little high. I don't care that the output data are limited to 16 bits. I just want to be able to receive data from the input jack and send the data that I create to the output jacks.

Sincere thanks,
Greg Berchin

Yes, you can do that with KX drivers... You just need to do some KX DSP windows routing. If you can't figure out how to do it let me know and I'll guide you. It's funny to know that Creative is sending their customers to kx site... hehehe Isn't that humorous?

Thank you; that's terrific news. I'll load the drivers and give it a shot.

Hard to believe that Creative would supply drivers, and then not put enough capability into them for a third-party developer to use them!

Well, I installed the drivers, and I think that I have a handle on the routing, but when I try to run my ASIO application it fails on init. Using "kX ASIO" as the driver name, it returns "ASE_not_present" when I call "ASIO_init(&asioDriverInfo.driverInfo)". Any ideas as to what might be wrong?

Thanks,

That's a question to KX gods... Maybe Eugene will pop in... KX ASIO works fine with Cubase, Logic, all VSTis I know etc...

make sure that you have hardware acceleration set to full for the kx card, otherwise ASIO will not work

Hardware acceleration did the trick. Thank you.
