All from s-sidin11-sid-factory-vs-ninjatracker (Ninjatracker V2.x, February 2007).

Track (one per voice, per subtune; orderlist)

value	meaning
`00`	loop
`01–7F`	play pattern `01–7F`
`80–BF`	transpose downwards
`C0–FF`	transpose upwards

Pattern row: note C1–B7, +++ (key on) or --- (key off) · command 01–7F (instrument if a note is given, effect otherwise) or 81–FF (legato) · note duration · the command's name (display only). Empty fields keep the previous values.

Command = ADSR · wave-table pointer · pulse-table pointer · filter-table pointer. ADSR is not used in legato mode; a pointer of 00 keeps the table already running (instrument-tables).

Wave table (left byte / right byte; wavetable-programming)

left	right	effect
`00–8F`	arpeggio: `00–7F` relative, `8C–DF` absolute note	set waveform (chord-arpeggio)
`90–BF`	—	no waveform; delay the arpeggio by `00–2F` frames
`C0–DF`	depth	vibrato with speed `00–1F`
`E0–FE`	speed low byte	slide with speed high byte `00–1E` (pitch-slide-and-portamento)
`FF`	destination	jump — not to be entered directly from a command

Pulse table (pulse-width-modulation)

left	right	effect
`01–7F`	signed speed	modulate the pulse width for that many frames
`80–FE`	value	set the pulse width
`FF`	destination	jump (can be entered from a command)

Filter table (filter-programming)

left	right	effect
`01–7F`	signed speed	modulate the cutoff for that many frames
`80–FE`	cutoff	set passband (left nybble − 8) and the channels to filter (right nybble)
`FF`	destination	jump (can be entered from a command)
