K, recently me n my friend (both beginers, me on guit n he on synth) tried to play together for a song. But none of us could figure out, exactly where the guitaring part should come n where the synth should come in. I mean i could tab all the stuff that he was playing on the synth. So my question is, how exactly fo u know, which part should be played by whom? n yes,.... listenin to the song again n again wasnt helpin, the original uses hell loads of instruments n effects. Pls advice.
