I am starting to do some drum tracks, and I have gotten to the point where the simple GM drums just aren't cutting it anymore. I want to record electronica style drums (tr808 or 909 style). I have Cubase SX 2 and Soundfonts and a simple MIDI controller keyboard. Ideally, I would like to use a general midi drum map, as simpler is better. How do I do this? VST instruments? Soundfonts? Could someone point me in the direction of decent free software? I know my questions aren't very specific, but I'm new to the world of midi, and I don't even know how to get started.
