The Asio4all control panel doesn't show the lightpipe I/O at all. I just checked. Reason is able to access all of the I/O in the PreSonus by using the PreSonus ASIO driver directly. If I switch to the Asio4all driver in Reason, those inputs and outputs disappear from the Reason audio I/O device in the "rack."

I only have one "soundcard," the PreSonus 1818VSL. (I suppose there's an internal audio device in the computer, but I never use it. So that would be two devices, total.)

If there's a way to get the Asio4all control panel to see the lightpipe, I couldn't find it in the control panel's Advanced Configuration area.

I'm attempting to use Pd to send audio to my eurorack modular so as to build a long step sequencer or whatever -- but there's a problem. My machine is Windows 7 64-bit, and I'm using 0.43.4-extended. My eurorack has the Expert Sleepers ES-3 and ES-6 modules, and I know they work, because Reason (running on this same machine) can both send and receive using them. They connect via ADAT lightpipe to a PreSonus 1818VSL.

Pd is unable to see the lightpipe I/O. It sees the analog outputs (line 1/2, line 3/4, line 5/6, line 7/8, and headphones), and it sees the S/PDIF I/O, but it doesn't see the lightpipe channels.

Has anyone else been using this type of setup successfully? Are there troubleshooting steps I could try? Settings in an .ini file? Suggestions appreciated.
