A beat is a grid of hits
Two rows, two instruments. An x is a hit, a . is silence:
rows:
- kick
- hat

kick x . . . . . . . x . . . . . . . # beats 1 and 3
hat 1 . 1 . 1 . 1 . 1 . 1 . 1 . 1 . # steady eighthsThe kick row points to an 808 drum, the hat row to a closed hi-hat — so
the same grid could drive any kit just by aiming the rows at different
instruments:
source:
kind: pattern
rows:
kick: kick-808
hat: hat(One bar shown; the pattern runs two.) Position is the only thing the grid carries; the sound comes entirely from what each row is pointed at.
