ok, with the audio clip it mainly good for adding samples,vocals etc.
if you are trying to create new sounds the n i suggest you try the sample interface and then layering several.
Back to your original question, go the insert channel button and add a new audio clip or just continue to clone the existing track and then go to the track properties and load in the next sample. go to the play list click in the bottom of the playlist in the audio clip section,and add it the click underneath it and add the next continue this until you have all the samples loaded, i hope this helps.
