# Half time

Half time runs at 130 to 150 BPM with the snare on beat 3 only, so the loop
feels like 65 to 75. The kick is sparse, the hats are sixteenths with rolls and
big velocity steps, the bass is an 808-style note that holds for beats, and
the harmony is a dark pad or a plucked figure. Use the 808 kit (25), gm:39 for
the bass at octave 1 (C1 to C2), gm:90 pad with `cut` 5,000 to 6,500, and
delay send 2,000 with `fx time 750` on a lead.

## Before and after

Before: `analyze` shows the bass in the `bass` band (F1 to Eb2) and the kick
and bass colliding on the downbeat of every bar and on step 11 of bars 1 and
3; the pad register is `mid`.
`lint` is quiet because the pad is voiced above C4 and the hats carry accents.

```sh
soundfish fill '<url>' trk_drums --bar 4 --seed 11 --operation op_roll
soundfish set-cutoff '<url>' trk_pad --points 0:3000:linear,48:7000,63:3000 --operation op_sweep
```

After: bar 4 of the drums gains a hat roll and a doubled snare into the
downbeat, and the pad's cutoff opens from 3,000 to 7,000 across three bars and
closes on the last, which is the movement a static pad needs. The collisions
remain; on this genre the kick and the 808 are meant to hit together, so leave
them and say so.

## Stage order

1. Drums first: place the snare on 3, then the kicks, then the hat rolls. The
   rolls are the genre.
2. The 808: one note per kick at most, long, dry, an octave below the chords'
   roots. `lint` will not flag a bass at C1.
3. Pad or plucked figure above C4 with a low cutoff.
4. A lead only in the second half of the loop, high and short, with delay.
5. `fill` on the last bar, `lint`, then `render --dry` when a checkout exists
   to confirm the bass owns the band below 120 Hz.
