A little late to the game on this one but...
*jack-rack for plugin effects (mostly dynamics but there's a boatload of
LADSPA plugins available)
*freqtweak for vocal processing from a mic input
*Pure Data for live sampling and looping with custom built patches
With a 2.4 kernel and JACK I get no noticeable latency playing as fast
as I'm capable of. It's not perfect though, some JACK apps decide to
crash at random intervals if left running for too long and I've noticed
that one bad app can ruin the whole signal chain.
