In the meantime, following along on Dave's idea about running remotely |
22 |
I now have Ardour running at 64/2. (sub 3mS) No xruns yet. |
23 |
|
24 |
1) On Lightning I boot without X and start Jack in a console. |
25 |
|
26 |
2) On my remote machine some audio apps are failing with lots of |
27 |
'BadAtom messages, but if I log into Lightning using |
28 |
|
29 |
ssh -Y lightning ardour |
30 |
|
31 |
then ardour comes up remotely and seems to be working fine. I've run a |
32 |
couple of sessions, and at least in playback no xruns yet. I'm also |
33 |
playing oggs from a 1394 drive and have hdspmixer running. My issue |
34 |
right now is this is a lot of network traffic and this room only has a |
35 |
hub so I'm off to pick up a cheap switch at lunch. |
36 |
|
37 |
I still see a lot of memory usage. That concerns me a bit. |

You make some very good points below. I'll come back later today and |
40 |
spend some time thinking and answering them. For now let me say that I |
41 |
have <1% of the experience you do with FB solutions (I've NEVER used |
42 |
it) so that's a whole new area for me to look at, but it could be |
43 |
interesting. |
44 |
|
45 |
More later, and thanks very much to you and Dave. I'm not done here. |

Cheers, |
