I'm an ambient looper and have used an RC-50 in the past and didn't like it for ambient due to the lack of feedback control per track/phrase. I know there's a workaround but it only works for 1 track and I need at least 2 tracks. Perhaps Roland will release a new uberlooper on Namm 2011 ;-) -- Sjaak Overgaauw http://premonitionfactory.com/ http://livelooping.be/
