hey, my buds and I are trying to put together reasonable recordings of our practice sessions. These will only be used by us to keep record of what we're doing (we improv alot). We have a fourtrack (cassette) and would like to couple that to a mixer (8 channel?). what I imagine doing is a combination of sending multiple mix channels to one record channel as well as single mix channels to record channels. This flexibility will hopefully allow us to correct any major level issues after recording. We want to spend a minimum of $ and will probably look to ebay- used and older is fine for our purposes. Any suggestions? We also need to be able to do minimal monitoring but don't really need anything too fancy. Am I missing/overlooking anything?
