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.
