Ok, so I have built my arch, and I know it works, I am using LSP and the AVD48 through a ECG-D4, I have tested the arch through David's test program. That tells me that I am using universe 13, and channels 1 to 10 (10 element's to my arch). Have input all the correct data into LSP, but when I try to test the arch through LSP, I get nothing. I am pretty sure I have all the correct info in the right places but its still not working, which suggest that I am a moron and have not put the info in correctly. Suggestions?
