I'm using a Delta 1010lt as my primary sound card but want to use my SBLive! card for the Midi metronome since the delta doesn't play midi. I've inserted a midi track and set the I/O to omni/sb live and don't get anything. How should this be set up so that the SBLive! ticks the metronome but sends all the audio (including the metronome tick) out the Delta?
