While playing (and sampling) my Microkorg I want to hear at least one drum loop played from the 404.

With other words: Is there any trick or setting to play a loop from the 404 while sampling external audio?

I think (still new to it but looked into this before buying)

You can play the micro through the 404,
but you cant record it to a sample while other samples are playing

you'd need something like a looper to do that. .. I was actually looking at getting the Kaos pad 3 to fill this role. . . you only get 4 4bar loops but it will instantly record/play back and then you can do all sortsa stuff like cut it up, effects, etc.

-and if you're worried about battery power, it shouldne be too hard to rig up the KP3 to run off batteries since it has a DC input you could just build your own battery pack with the right plug on it

Any other ideas? Sorry for my impatience but play-while-sampling is essential for me and until tomorrow I can give the SP-404 back for refund.
