DJm-900nxs2 future feature request 100% feedback loop effect

you mean reverse roll?

That'd be good as roll and slip roll sound the same already , they could change slip roll to reverse one

Hey guys, while roll and slip roll may sound the same at first glance, try engaging the effect and then changing the timing.  That's where the difference lies.

No I mean FEEDBACK LOOP either echo like in the video with Gavin

Or the EFX-1000 with James Zabiela

i already know what the difference between roll and slip roll I own 2 RMX-1000 them even have a divide roll too

I want to second this request... the echo level depth seems really limited and i can't seem to get an infinite echo from it if I want to.
