R: Drum machine for loops

["luca" <lucafeed@tin.it>]

And what about Roland's R8 ?
I finally have found one of those after having sold mine a few years ago.
In my intention there is to make it drive midi changes of my Edp and of my
future Yamaha A4000 Sampler (I think it is maybe the most looper-friendly
sampler).
Does anyone know what an R8 can do with this set-up?
