- Place Spark on a MIDI track
- In Spark open the bottom window, go to the mixer tab
- Press and hold the first button under the track number, in the popup menu you'll see a list with "Master" and many "Out x" entries
- For a test select "Out 2" i.e. for a kick track (with some sound on it)
- In Live now go to an empty audio track in the session view and arm it
- Under the clip slots, click on the "Audio from.." popup menu and select your Spark track (normally named "Spark")
- A new menu will appear just below with "Post Mixer" as standard entry. You will also hear the master output from Spark on this track.
- Open this menu and if Spark is just playing back a kick, you should see a little green blinking volume icon next to the entry "3/4 Spark"
- Select this entry and now you should see and hear only the kick playing in the new audio channel
With this procedure you can go on for every track in Spark, just keeping in mind that the method of numbering the tracks/channels are different in Spark and Live. Both are stereo channels/tracks, but "Out 2" in Spark means "3/4 Spark" in Live, "Out 3" in Spark means "5/6 Spark" in Live, "Out 4" in Spark means "7/8 Spark" in Live and so on.
Hope that helps
