A newbie could use some help...I want to buy Toontrack EZdrummer and some electronic drum kit -most probably by Roland (nothing out of the ordinary). I have an M-Audio 2496 soundcard. An electronic drum kit has a cable for every drum/cymbal, right? And each one of them should go into the soundcard, right? Since the soundcard has fewer inputs than an electronic drum kit needs, I assume I need something more than that . I hope it is not as expensive as a mixer. Maybe some preamp?
