hi,

i might be getting one of these but i have a few questions if you folks can help me out:

im wondering about using the e6400 ultra in a live situation. i want to use the inboard sequencer to trigger "songs" that are simple arrangements of loops, not actual midi data, and at the same time be able to play keyboard patches/samples. also what are the possibilities for mixing into other loops and improvising which song/sequence you are going to move into next?

and a longshot question can you record midi sequence loops in real time thus using it as a looping machine so i can move over to the guitar or bass and play that? (not recording audio data but just midi like when im on the sequencer and you throw down an overdub)

thanks
