Hello, Many advanced apologies for my ignorance. I have a Yamaha 4 track, analog. And one mic. I use it for vocals. I also have a pretty respectable four piece indie rock band. Guitar, Base, Drums, Vocals. I'm looking to start recording. WITH my 4 track. With THE VERY BASICS in mind, what do I need in the line of mixers, processors, mics, etc. I just want a demo-type end product. But it would be nice if one could actaully listen to it. Am I asking for too much help?
