Hi !
Well, that didn't help me at all. For example, I have a computer with a
Midiman Delta 1010 LT.
The DirectKS reports that I have 1 (ONE) device: - Midiman Delta 1010LT - 12 in / 10 out
The point is that I want to use the DirectSound, NOT the DirectKS. So, DirectSound does NOT report 1 device, but 6: - M Audio Delta 1010LT Multichannel (which has 12 outputs) - M Audio Delta 1010LT 1/2 (2 outputs, just a simple stereo DS device) - M Audio Delta 1010LT 3/4 (2 outs) - M Audio Delta 1010LT 5/6 (2 outs) - M Audio Delta 1010LT 7/8 (2 outs) - M Audio Delta 1010LT S/PDIF (2 outs)

Check the old board messages->there is an example for directks. Maybe it includes something about that too.
Look for directks.exe.

IMV> Because I don't know how to get the actual number of the channel the device
