Followup to my problem yesterday: jack_lsp showed 107 ports total between hydrogen and ardour. I still bumped the total up to 256 to be safe. How badly will this affect memory usage? I was never able to get Ardour to re-open my session, it must have gotten corrupted somehow. I deleted it (luckily, the three tracks I already had were created from external files I had imported in) and just rebuilt the session and haven't run into the max ports issue again yet. -- Brett ----------- Programmer by day, Guitarist by Night http://www.chapelperilous.net http://www.alhazred.com http://www.revelmoon.com
