Glad to help!  This is what I've sort-of been doing for a while.  Do you
need to set the DL4 into "one shot" mode or something?  Doesn't the 
external
fb not just add to the internal fb?

Sounds like the same idea.  As I said when I think I may have started this
thread, the one drawback with this is that you can't get 100% regeneration:
eventually, 99.9% will disappear and 100.1% will swell and distort.

The best cheap looping device for me would be the new Zoom GFX8 which has
tap-tempo delay and swell-pedal type feedback control.  If it had more than
6 seconds max I'd get one today.  It's frustrating, particularly when
there's loads of unused memory going to waste providing 12-second phrase
trainers.
