Recording drums via midi
Alright I'm new to all of this (Midi, and recording on a PC) so please just humor me a bit. I have an alesis DM5 electric drum kit, I want to hook it up through the midi ports. First of all assuming this is possible, can I arm each track to recognize each trigger seperately for mixing and such later? Will the sound the DM5 sends out be the ones recorded? Assuming these things are possible, is there a way to lay out a tempo map so any imperfection can be quantized easily? Like I said, I consider myself ignorant right now and I need to learn a lot so the more help, the better. Thanks
