yup, i use reaktor--and no, you will not be able to run it and other plugs at the same time. i am using an ibook g4 with a gigram, and while running Live 5, I can only use one instance of Reaktor as a plug. i don't really use the reaktor sequencers...i basically use it for sound design. i haven't gotten into building my own synths yet...no need just yet. the ones that are provided are pretty deep. you can email me at
shane@dirty.org if you have any working questions. truthfully, once i got my crashing issues worked out, it pretty much ran right out of the box.
