Effects Dxx

All of these commands perform a volume slide but on different mixers. Operations on the values are saturating.

Canonicalization
Values where both nibbles are in 1..=0xE
at the same time don’t have a defined meaning, these
get skipped by the parser.
Value 0xFF
gets parsed by OpenMPT and Schism Tracker as FineUp(0xF)
, however this makes it
non-symmetrical and also doesn’t agree with OpenMPT documentation and makes the parsing
somewhat ambiguous (although at least two implementations agree on the way to parse it).
We enforce that FineUp
cannot exceed 0xE
. We parse the value 0xFF
the same way as 0xEF
for compatibilty with these trackers.
Variants

, N0x

Volume slide down by x
Decreases mixer volume by x
units on every tick of the row except the first.
If x
is 0xF
, volume decreases on every tick (including the first).

Fine volume slide down by x
Finely decreases mixer volume by only applying x
units on the first tick of the row.
