Patching a Gate - Delay/Looper/Echo

#1

I'd like to patch a trigger/gate delay/looper (echo) & not sure how to.
It would be great if the object "delayedpulsedurationm" had a feedback control, so with sufficient feedback it would become a gate-looper. Controlling "delay" would change the loop-length.
I have this idea from the hardware-box Flame Echometer I had some time ago.
Putting Echo on Trigger/Gate signals can give repeated patterns (loops) & playing with delay-time spits out bursts & all kind of weird, mangled rhythms!
One can experience this "effect" with some electribe boxes & volca beats:
having echo on drums with a high feedback you can "re-sample" yourself twisting the time-knob & creating funky-fresh overdubbed poly-blabla rhythms.
When one does this with gate signals, one is free to change the signal which gets triggered, by this echoed gate-mush.
Let me know any ideas on this? Thanks!!
