So I've watched several different tutorial videos on creating tracks, getting started, etc.  But I cannot get anything to actually record. Here's all I'm doing 1) Dragging in Instrument (SI-DrumKit) and accepting the defaults. 2) Make the track Hot, and click the instrument icon to bring up the drum kit 3) Click the Record button and beat on some drums 4) When I click space bar to stop recording, there is nothing in the clip box.  It's like no audio ever gets through, al
