 Each cell carries a 6-bit value field plus a 2-bit selector field for the volume column. The four selectors are:
 
 - **`0.$xx` — Set volume** to `$xx` (6-bit, $00..$3F). Equivalent to a note's default volume.
-- **`1.$xx` — Volume slide up** by `$xx` per non-first tick (6-bit). Volume clamps at $3F.
+- **`1.$xx` — Volume slide up** by `$xx` per non-first tick (4-bit). Volume clamps at $3F.
-- **`2.$xx` — Volume slide down** by `$xx` per non-first tick (6-bit). Volume clamps at $00.
+- **`2.$xx` — Volume slide down** by `$xx` per non-first tick (4-bit). Volume clamps at $00.
-- **`3.$Sx` — Fine volume slide** on tick 0 only. The high bit `$S` of the value selects direction (0 = down, 1 = up); the low 5 bits `$x` ($00..$1F) are the magnitude. Equivalent in scale to `D $xF00` / `D $Fy00` but with a 5-bit cap. Fires once per row regardless of speed.
+- **`3.$Sx` — Fine volume slide** on tick 0 only. The high bit `$S` of the value selects direction (0 = down, 1 = up); the low 4 bits `$x` ($0..$F) are the magnitude. Equivalent in scale to `D $xF00` / `D $Fy00` but with a 5-bit cap. Fires once per row regardless of speed.
 
 Volume-column effects do not consume the main effect slot; a cell can carry both (for instance, a tone portamento in the effect slot and a volume slide in the volume column).
