Hi there, you seem to have posted a few questions on the same subject area of recording live bands in bars….
Ok the area of sound and recorders is simple…..basicly what you feed into the recorder is what you get out…
So what you want to feed into the Edirol (or other recorder)?
In a band shoot you need ALL the things that make noise.. ALL the instuments and the vocals and anything else you may see ie. the crowd.
You may need to use a sound guy to do a complete seperate mix for video to get all these in balance….
Or you can use a recorder on the o/p of the mixing desk (but this will NOT give you a full sounding mix as it wont have the instrument amps or crowd fx in it) which is the track you seem to be going down (but also how are you going to sync up your video to the recorded sound?)
Or you can use the recorded sound and video from you camera as the product…
Good luck with your shooting…..
