How To

What are the functions of the parameter and the command bits in the sound data format?

For my piano roll program I'll be using the NX sound data format. I understand most of it, but I have no clue what the four parameter bits and the four command bits of a track are for.

Reference:
Each track occupies 96 bytes and consists of 32 entries with each 3 bytes:
- Note pitch (0 = empty)
- Data (ignored if note is 0):
. . . Bit Purpose
. . . 0-3 Volume
. . . 4-7 Sound
- Control:
. . . Bit Purpose
. . . 0-3 Parameter <-- what are these for
. . . 4-7 Command

The sound commands are described at the end of the Sound Composer chapter in the manual: https://lowresnx.inutilis.com/docs/manual.html#Sound-Composer

A sound command looks like this for example: E8 -> set speed (E) to 8. Most commands are for changing instruments, which is hardly used.

I'm now working on a sound effect automation panel to control these commands
