I think this might be because ardour records to separate files. I just
tried recording 128 channels in ardour using 16 X 8 channel tracks,
and it failed quite immediate. Recording 128 channels using jack_capture,
on the other hand, seems rock solid. Recording 64 channels (8 X 8) in
ardour seems to work fine too.
However, it could also be because Ardour does some graphical operations
while recording. Is there any way to turn off all that?
Perhaps this is an area where Ardour could be optimized quite a bit?
