I am running Sonar XL 2.2 with an Echo Gina 24. The Gina only has 2 analog inputs, but it also has 8 tracks of digital I/O via ADAT lightpipe. I have a blackface ADAT connected to the Gina; With a JL Cooper Datasync2, I transfer tracks back and forth between Sonar and the ADAT. Recently I decided to try to record 10 simultaneous tracks (mics and DIs) by using the ADAT as an A/D converter. No tape in the ADAT; it was set to send its analog inputs to the digital outs. The Echo console was set to use ADAT as the input clock source. All went well and sounded great, except that over the course of about 30 minutes of recording there were 3 gaps of less than a second each where all of the digital tracks recorded nothing; i.e. Sonar's waveform display shows nothing for those gaps. The analog inputs did not have the problem. I was hoping I had found an expensive way to get 10 tracks out of my Gina. But obviously the gaps are unacceptable. Any thoughts on what would have caused them? And, more importantly, what I can do to eliminate them? I'm guessing it has something to do with using the ADAT as the clock source, but I don't know what the alternatives are. Thanks in advance for any replies!
