I've got everything recorded using Tascam MF-P01 cassette 4-track and audacity on my computer but I need a good way to get my drummer recorded and being able to hear all his set.
Depending on how many you have, try one, or a spaced pair above the kit, and one on the kick, one on the snare. This article gives a pretty good description of placement. http://emusician.com/mag/emusic_capturing_kit/index.html
