thanks alot sicijk, just workin’ this out now 
my set up is this:
PART 1
track 1-track 5 patterns/plocks/scenes crossfade scenes
track 2-track 6 patterns/plocks/scenes crossfade scenes
track 3 oneshot rec trig 64 scale, crossfade to left
PART 2
track 7 oneshot playback trigger, 64 scale crossfade to right
it works like a peach, continuous playback of internally recorded jam.
but then when I stop playback and start again ,the sampling process starts and the recorder buffer is wiped.
I know I can save/assign sample but it seems abit fiddly.
