I miss my Edirol solely for the "all in one HQ recording box" that ran on 4xAAs for hours..and fit in my field bag.
the Zoom..., its not a field deck ...in how we would use it for concert taping. sure, it can be done, but its not quite as easy.
you dont just turn it on and hit "record" ..for example.
you have to create a project, all of its parameters..., etc..., then record. and everything is a single mono channel that you have to mix in post.., even if its just two channels from a pair of mics.
If I was using mine for concert taping only, it would be sold by now as a matter of inconvenience. But for what I bought it for..., I love it.
