[LAU] Simple WAV-based looper with MIDI control?

Apologies if I've posted this before, or if it's been answered already, but I'm looking for a simple looper that: 1) Works with stereo WAV files 2) Is loop-oriented not sample-oriented (i.e. not like Jackbeat) 3) Lets you pre-load the loops and stores them with the file (i.e. this disqualifies SooperLooper, from last I played with it). 4) Is very CPU-stingy enough to run on a netbook. 5) Is very stable and won't die in the middle of a show (i.e. not Freewheeling, last I used it) 6) Has MIDI controls for the loops and levels/mixer/muting for them. 7) Can handle up to about 5 simultaneous loops (i.e. not like some of the DJ-oriented stuff that handles only two at a time). 8) Of course, is JACK-ified and RT capable. 9) Optionally has some way of picking/moving loop points, though that's not so critical since I can use Rezound for that off-line. Hmm, after writing all that, it occurred to me that ecasound might be able to do this, which I'd be perfectly willing to try. But I've had a rough time with ecasound and ALSA MIDI so I'm a bit concerned about item (5) above. -ken
