Ok took alittle testing cause I just got this program myself.
But to answer your question here goes.
Open up a project in audio mode.
1. Target your sample or wave or what ever it is =)
2. Click on "Transport" and you should see (metronome on/off)
the hot key is "c" turns the "click" noise on or off.
3. to controll the tempo, go to "Project" then "tempo track"
Thats what I see and thats what works for me.
No need to record anything. Just dont run it on MIDI, start your project as "24 track audio" or start a new project "empty" and add an audio track.
Its not hard just have to learn where stuff is.
Hope that helped, cause I read your post this morning. And I was wondering the same thing, till I played with it alittle more.
