Hi Digger,
its this "wonderful" button in your DAW which lines everything up with the beat. In the olden days, when I was a lad, you had to rely on the internal clock of the musicians or a metronome to get the timing right, nowadays its all done by "magic".
I watched the Rolling Stones documentary Crossfire Hurricane last Friday. Bill Wyman explains it in a roundabout way. Keith Richards is the time keeper rather than Charlie Watts. Bill Wyman played slightly in front of Keith's beat with Charlie slightly later. Nowadays they could be all on the beat as the producer can quantise each track to make the instruments all arrive at the same time. The wonders of modern technology, or not, depending on your taste.
I'll have a think about the bass drum.
Your explanation of the song has thrown me a curved ball (a US expression if you haven't heard it before), so a bit more thinking needs to go into the mix.
With a bit of luck we'll get our tickets for Barnsley later today.
Take care,
Diadem
