Live mode would be awesome, but seriously the two things that are keeping me from using Klystrack as my main tracker (and not one that I just kinda diddle with) are
-MIDI clock out: being able to sync my Game Boy is a big deal for my setup
-MIDI controller knob assignment: being able to use my knobs to tweak parameters on the fly is also a dealbreaker
I've liked Klystrack since the beginning, but it's just missing a couple things that I need at the moment
