I've done multitrack recording before using ardour, jack, zynaddsubfx,
a midi (usb) keyboard, non sequencer and some other stuff. I recorded
at 96k (I should have use 48k), but I didn't get anything like the
xruns I am getting with mplayer.
But that was a few years ago, on a different kernel, which IIRC was
setup for low latency. I guess I'll have to do some kernel compiling
again to see if it helps. It's been a while.
