Hi Jeremy! My MIDI interface is an M-Audio MIDISPORT Uno. Unfortunately the only sound device I have available at this time is the built-in on-board sound. Alsamixer reports it as "card: HDA Intel PCH, Chip: Realtech ALC892." Apparently my Rolland OctaCapture isn't supported at present, or I would be using that. Currently my Jack-2 settings are: –realtime –timeout=4500 –no-m_lock -d alsa –device=HW:0 –rate=44100 –period=256 –dither=shaped midi=none. I haven't had a chance to try larger latency yet, but I could do that once I'm playing back sequences. Is there any reason to do anything with "nice" on either A2J or anything else? I think I have most of the recommended optimizations for audio done, except for the rt kernel, but just wondered about nice, since I've seen it used, but don't see any recommendations about it. The uname -a shows: Linux StudioLinux 3.5.0-42-generic #65~precise1-Ubuntu SMP Wed Oct 2 20:57:18 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Studio is just its name reflecting location, it isn't a special blend of Linux. Thanks much for your help.
