This is a part of a treatise on a system to handle music modules in CSV, or maybe pipe-separated values. It is advisable to store the effect type as a single ASCII character instead of a 2-hexit number. There is an unfinished university project of mine called ReTeMuS (Renderer/Redactor of Text Musical Sequences) that was supposed to support multiple effect letter semantics, as per song configuration, but JavaFX with its Observers just sucks. Most music module formats are binary, which is very unUNIXy. Renoise uses XML, which is not much more readable for humans. OpenMPT and Furnace clipboard is text-based, but COBOLesquely fixed-width. It's possible to make ChatGPT generate some patterns in such format, but it's very uncreative. OpenMPT developers aren't exactly keen on big new features, so ReTeMuS is sort of like Renoise for cheapskates using unmnemonic effect letters. The main reason for ReTeMuS has been to have native xenharmonic support, because 12EDO is full of copyright lawsuits. See also a Czech article about note names and accidentals for microtonal tunings.
There are 4 main families of effect letter nomenclature:
MOD -> MTM -> XM -> MT2 Protracker -> Multitracker -> FastTracker -> MadTracker
STM -> S3M -> IT -> MPTM ScreamTracker 1/2/3 -> Impulse Tracker -> Modplug Tracker
RNS -> XRNS NoiseTrekker ~> Renoise
669 ~> FAR Composer 669 -> UNIS 669 ~> Farandole Composer
Scroll way below for FM synthesis. Radium doesn't really use effect letters. There're synthesizing trackers like AHX, HivelyTracker, Klystrack, StarTrekker, Buzz, and Psycle, but they are out of scope. Art of Noise has crept in because it's Protracker compatible and OctaMED also has wavetables. SunVox has crept in because of effect column similarities to MadTracker.
The pace of tracker development was very rapid. Once people figured out software mixing on Amiga, the channel limit went to the moon, while on PC we got NNAs:

SAMPLE-BASED
I've decided to sort the table according to XM effects, since the
Protracker subset is generally agreeable, even though the letters G..Z or hex 10..FF
are wild west. I mostly follow OpenMPT's extensions as they backport the
IT effects, MT2's are a whole different can of worms. Some effects could be described in Italian like in classical music, but EDM, DAWs, Computers, and the Internet all use English.
Keep in mind that each implementation behaves slightly differently in certain edge cases. Some effects may be per note, others per channel, coarse slides may also update mixer on 1st tick of row too, fine slides may slide on the 2nd tick, the FT2 E60 has a bug that mandates use of D00, F00 may either stop, hang, or crash, PT2 could do wavetables with on-the-fly sample swapping and offsetting, the small volume column effect parameter mapping to the big effect column effects differs between IT and XM, speed in LFO type effects may be interpreted differently, effect memory is shared differently, Furnace has persistent effects that are stopped instead of continued with zeroes, and so on and so on. *sniff*
Pipe (|) and comma (,) are reserved for separators. IT column also disregards double quote (") for string escaping, dot (.) for denoting empty space, and equals (=) for denoting Excel formulae, because I ran out of ASCII. The upper half of the codepage is used for semigraphics tiles. We have Unicode terminals now, but entering Unicode letters and symbols with arcane compose sequences, by switching around multiple keyboard layouts, or having to hex-dial with Ctrl+Shift+U is UX from hell.

Note: Renoise has a separate volume, panning and delay column. Delay column only accepts effect exx, effects ix and ox are exclusive to volume column, and jx and kx are exclusive to panning column. ReTeMuS is all-forgiving, for it doesn't care.
Note: HivelyTracker, DigiBooster 3, and AdLibTracker 2 have another full effect column instead of a volume column. Famitracker and DefleMask let you have 4 full effect columns in addition to a volume column, and Furnace even 8. Once the volume column stopped to be only for volume in FT2, it's to be expected that users will try to put an effect into the wrong column. Also someone will definitely mix hexadecimal XM/RNS volume column effects with IT decimal ones, so better define interpretation for values A..F or 41..FF for the IT ones. For example v255 or vFF would be ~4x amplification and p65 to p255 would continue running quadraphonically along the square, which would make for "8D" effect. Or gA..gF would be fine note portamento 1..6 16ths of a semitone.
Note: Some effects internally exist in libOpenMPT for backwards compatibility, but they are inaccessible from OpenMPT UI, so my letters are pure invention. These are: {xy, }xy, {xy+Rzt, }xy+Rzt, X9F+9xx, X96/X97, o0+9xx, .xx (dummy), X9E/X9F, AON Gxx (8bit Cxx), X00+0xx (HMN 7xx), Lxx (8MED Exx)
Note: Furnace recently changed the sample offset effect to allow for selecting offset byte, instead of employing parameter extensions like OpenMPT. Currently only 3 bytes are supported up to 92xx, meaning you cannot jump past sample 16777215 (6m20s of CD audio or 87s of 192 kHz hi-res master). I suspect Furnace will use 98xx and up for some sort of cue system or counting from reverse. Also work is being done to import Impulse Tracker modules, which means more effects are coming.
Note: FunkTrackerGOLD is heavily volume-centered, probably due to lack of volume envelopes. The echo is a true DSP. Was the 1st tracker for *NIX, discontinued way before Soundtracker (XM effects) and Cheesetracker (IT effects) came out, will only work with OSS (modprobe snd-pcm-oss). The code uses nested functions which aren't standard C90, and sys/stat.h defines are broken. After getting it to compile without any -Wextra warnings in -std=c90, it segfaults when trying to play, and valgrind constantly breaks on Manjaro due to missing debuginfo, so can't fix.
MadTracker 2 wide effects
In MadTracker 2, any XM effect can be specified with 00xxyy, and any IT effect can be specified with 10xxyy, xx being displayed alphanumerically for XM (Z=35=23h) and alphabetically for IT (Z=26=1Ah). Extensions beyond that range (like \xx #xx :xy &xx $xx) are not supported. The proprietary effects have very long words. There's also separate panning column supporting only Lx and Rx, and volume column supports only Ux and Dx.
Also MT2's antipiracy model of not opening modules made with old cracked versions was flawed because it punished those who had repented, and new cracked versions made sure to patch it, besides it's basically abandonware anyway. With a little bit of extra office work, all the limitations of unregistered version can be gotten around, just like with the mono-only file output driver of Impulse Tracker 2. But pirates gotta pirate, just like with The Ultimate Soundtracker. Remember where the demoscene came from, and these people can crack Denuvo. Also you can't put any DRM in a plain text format.

OctaMED MIDI reminder
In OctaMED, cetain effects take on different meaning with MIDI instruments (probably an implementation detail, but maybe add $4000 to avoid conflicts):
00xx - MIDI controler value (select with 05xx) [Zxx]
01xx - MIDI pitch bend up
02xx - MIDI pitch bend down
03xx - Set MIDI pitch bend [Ixx]
04xx - MIDI modulation
05xx - Select MIDI controller [EFx select macro]
0Cxx - MIDI velocity (0C40 is MIDI 7F)
0Dxx - MIDI channel pressure [Vxx]
0Exx - MIDI panning (00..3F..7F) [8xx]

Amiga history
You can sometimes see remnants of old Soundtracker pirate editions effects, before everyone agreed on Protracker ones. Taken from https://web.archive.org/web/20230316093224/http://helllabs.org/tracker-history/trackers.svg , which misses Symphonie Pro and MultiTracker.

Oktalyzer has few somewhat intuitive effects (actually base36, format description was unaware of presentation), with bespoke arpeggios:
1xx Portamento down [E30+1xx]
2xx Portamento up [E30+2xx]
Axy Arpeggio 3: -x,0,+y [3FF @ F01 or ?xy]

There's quite interesting Art of Noise, which has letters like FastTracker, but different, mainly for wavetable synthesis. Protracker 1 and 2 solved it by simply allowing to swap the sample on the fly and version 1.1 had the Funkrepeat effect, which moved the loop points. Later Protracker versions had Invert Loop effect in its place which trashed the sample data by randomly sign inverting samples. Other Art of Noise effects try to get around having only 1 effect column, and unlike 5xy and 6xy the parameter is not just volume (letter marked orange):
E5x - set loop point [E60]
Gxy - set volume to 4*x+y+4 vblanks (dunno what vblanks have to do with volume)
Hxy - synth control (x keep wave bool, y keep envelope bool) [E08/E09+E0A/E0B]
Ixx - wavetable speed [EFx funkrepeat or $xx]
Jxx - set arpspeed [X0x]
Kxx - set volume & continue vibrato [Cxx+400]
Lxy - fine volume slide & portamento up (volslide x, porta y) [EAx+20y]
Mxy - fine volume slide & portamento down (volslide x, porta y) [EBx+10y]
N0x - avoid noise (wave < 512 B, bool) [;0x]
O0x - play samples > 128 kB (bool) [;x0]
Pxy - fine volume slide & continue vibrato (x up, y down) [EAx+EBy+400]
Qxy - volume slide & portamento down (syndrums) (x porta, y volslide) [10x+A0y]
Rxx - set volume & continue tone portamento [Cxx+300]
Sxy - fine volume slide & continue tone portamento (x up, y down) [EAx+EBy+300]
Txx - set track-volume [Vxx]
Uxy - set wavetable mode (x freeze, y never reset) [E0C/E0D+E0E/E0F]
Vxx..Zxx - unused, unused, extenal event 1,2,3 (sync) [&xx]
DigiBooster 1.6 effects (only those different to ProTracker):
8xx - Robot ("metallic" effect, "I am Iron Man"?) [Txy]
E3x - Play sample backward, x=1 "next from front loops" (sic) [X9F]
E40 - Stop playing sample (performance reasons) [EC0]

669 -> UNIS -> Farandole
Composer/UNIS 669 has only 6 or 8 effect letters and the effects take only 1 nibble as the parameter. Also the tick rate is slightly less than 32 Hz, which amounts to 78 BPM at "speed" 6 and 4 rows per beat, which is why the default "speed" was 4, so 117 BPM. Panning has only 4-bit precision, which makes panbrello impractical. Volume being 4-bit is fine, tremolo is just more like gate.
Ax - Portamento up [10x]
Bx - Portamento down [20x]
Cx - Portamento to note [30x]
Dx - Set finetune (5/8 semitones up in XMP, nonlinear FFx in OMPT) [E1x]
Ex - Persistent vibrato depth (actually more like 2-note arpeggio) [40x/0xx]
Fx - Set "speed" (F0: Super Fast Tempo™) [F0x]
G0 - Fine panning slide left [P4F]
G1 - Fine panning slide right [PF4]
Gx - (unused; Fvol, Fporta, gliss, filter, Ftempo, offset mul, patt break?)
Hx - Retrigger note with speed x [E9x]
Ix..Ox - (unused; note cut, note delay, patt delay, loop, tremolo, pan, offset?)
x - volume (separate column, 4bit)
The successor to UNIS is FunkTracker(GOLD), which has had the letters considerably rearranged and the effect width was expanded over the volume column, like MultiTracker.
Farandole Composer looks like Composer 669 with 16 channels, but has 16 completely different effect letters vaguely closer to ProTracker, and a very outlandish tempo system centered around GUS. Could be a nice complement to FUR set in GUS mode (10xy - Farandole Composer effect, FC10xy in MT2):
03 - Fulfill sample loop (cuts note due to bugs) [EC1]
04 - Old tempo mode (allow slow tempos due to underflow, process at 4 Hz)
05 - New tempo mode (default 32 Hz)
1x - Pitch offset up (4*x GUS frequency steps @ 16 channels) [E1x]
2x - Pitch offset down (4*x GUS frequency steps @ 16 channels) [E2x]
3x - Persistent note portamento (rows to complete in, but scales with tempo)
4x - Retrigger note x times in the row (subdivide, 0 is crash)
5x - Set vibrato depth (global, default 4) [X4x]
6x - Vibrato speed [4x0]
7x - Fine volume slide up [EAx]
8x - Fine volume slide down [EBx]
9x - Sustained persistent vibrato speed
ax - Persistent slide to volume (2* faster than 3x)
bx - Set panning [E8x]
cx - Retrigger once on tick x (supposed delay with timing like 4F, c0=4F)
dx - "Fine" tempo slide down (cursed) [XEx]
ex - "Fine" tempo slide up (cursed, up to 100) [XFx]
fx - Set "coarse" tempo (cursed, higher->slower, [256, (128/i)]) [F0x]
x - volume (separate column, 4bit)
This was very obscure. Thanks to AliceLR AKA Lachesis for write up and libxmp implementation, and complaining about inaccurate import: https://bugs.openmpt.org/view.php?id=1541 . Nobody seems to have really used Farandole, as when it was released in 1993, there was already Multitracker with full 32 GUS channels and familiar Protracker effect syntax and semantics, although no volume column, and on the horizon was ScreamTracker 3 with 16 digital/GUS channels and 9 AdLib channels, richer effect repertoire, and no scary evaluation period language.
There's also format specification archive at ModLand: https://ftp.modland.com/pub/documents/format_documentation/ . If you know some Finnish, this paper discusses the history of trackers: https://musiikki.journal.fi/article/view/87867/47085 .
WaveTracker
A wavetable-oriented tracker with vertical pianoroll visualization, in addition to per-channel oscilloscopes. The 6px proportional font is very small, so no Hi-DPI screens. Also only 24 channels, but maybe that will eventually increase. Effect letters resemble Famitracker a bit, but it's another tracker that had to make their own. Effect parameters that are not nibble-split are decimal, sort of like ST3's pattern break. There's a separate decimal volume column, and I guess the instrument column is also decimal. As is typical for chiptune trackers, instead of effect memory, the effects are continuous and x00 turns them off.

PolyEnd Tracker+
A hardware tracker for DAW-less musicians. Has an FM, wavetable, and granular synth, and many keys that resemble a PC keyboard. But has only 16 tracks (channels) after an upgrade from 8, and sample RAM in the order of MB, which is too little for $799 (non-Plus was $599), which is the cost of a new PC with Renoise. Of course PolyEnd had to make their own effect alphabet, as if there wasn't already enough of them. There are 2 effect columns, commands are alphabetical, parameters have 3 digits and are decimal, some have a sign. I had to objdump the firmware and look for strings in it to get the full documentation, RTFM wasn't enough.

FM SYNTHESIS
Due to my procrastination, below is an FM effect list (actually phase modulation), sorted by AdlibTracker 2. MPT column is a superset of Scream Tracker 3, as Impulse Tracker supported FM only as a MIDI device, and ST3 didn't support OPL3. Famitracker column considers only VRC7, which is a cut down OPLL. BambooTracker supports only OPNA. Furnace column also considers OPZ, an expanded OPM, and ESFM, an expanded OPL3. DreamTracker for Commander X16, namely its OPM or OPP chip (differs only in test registers and timer resolution), recently got full 2 bytes for effects, but VERA PSG is omitted to reduce clutter, as has already happened with OPZ and ESFM.

40.. OP2, 60.. OP3, 80.. OP4, A0.. unassigned
Note: In AT2 parlance, "extra fine" means executed every 4 frames (ticks), even for pitch effects. The effect parameter range is not altered.
Note: In MPT, Oxx is reused for modulator volume and Zxx usually for carrier volume, I've also reused SAx for OP3/M2 and S0x for OP4/C2 volume.
Note: Furnace's effect letters are not necessarily compatible between different FM chips. This is apparent with OPZ and ESFM.
Note: DreamTracker uses Modulator 1,2 and Carrier 1,2, which is confusing given Furnace's OP1..4 and Adlib Tracker modulator 1, carrier 1, and then on 2nd 4OP channel halves modulator 2, carrier 2. OP2 and OP3 is thus probably swapped between on OPM compared to OPL3.
Note: DreamTracker uses direct register mapping, which sometimes contain more values, not always at nibble boundaries. The position is hinted by using _x for lower bits and x_ for upper bits.
Note: Basically everywhere except OpenMPT the volume column is only for volume. AdlibTracker 2 has 2 full effect columns instead, and some effects have pair synergy.
Reality AdLib Tracker has few effects:
1xx - Slide note down (pitch bend)
2xx - Slide note up (pitch bend)
3xx - Slide to note
5xx - Volume slide while continuing note slide (01..49 down, 51..99 up)
Axx - Volume slide (01..49 down, 51..99 up)
Cxx - Set volume
Dxx - Pattern break
Fxx - Set "speed" (ticks per row)
Ixx - Ignore note transposing (only in Riffs)
Mxx - Set Multiplier (only in Riffs, Channels 2..5 and 6..9 affect OP1..4)
Rxy - Play Riff (x which, y channel, y=0 stop)
Txy - Play Riff transposed (provide a note)
Uxy - Feedback (only in Riffs, x which 0/1, y value 0..7)
Vxx - Operator Volume (only in Riffs, Channels 2..5 and 6..9 affect OP1..4)
SoundFX, not having quite many FX:
1xy - Arpeggio
2xy - Pitch bend (x down, y up)
300 - LED on (set bit 0 at address 0xbfe001)
400 - LED off (clear bit 0 at address 0xbfe001)
5xx - Fine volume slide up (add xx to current volume)
6xx - Set volume
7xx - Set step up
8xx - Set step down
EdLib (incomplete):
6000 - Cut
7xyy - Vibrato
90xx - Levels
Bxxx - SpFX sound
Cxxx - Instrument
Dxxx - Slide up
Exxx - Slide down
Surprise AdLib Tracker likely mostly follows the ProTracker nomenclature. MasterTracker (or MasterPlayer) and Composer 667 don't seem to have per-channel effect columns or they have some event editor on other screen or in another window like Symphonie Pro. Internet in the 2020s seems really quite barren compared to 2000s when I 1st found out about trackers.
There were other Famitracker extensions and modifications which added more chips or targeted different chips, but Furnace made them all obsolete by supporting all of them at the same time, even if it didn't make historical sense. Therefore these chips are approached more like modular machines in Buzz, yet they provide for nostalgic attachment and allow leveraging of existing know-how. There's still a possibility of making a cartridge with such unlikely combination of expansion sound chips, just like it was done on NES, which inspired the original Famitracker.
SID
The filters are what makes SID sound trippy, VIC-20 "squares" are close, but Atari square is Metal. Ordered according to GoatTracker Ultra, even though it has fewer effects, because it runs in SDL on other computers and supports microtonality and quad SID, and Furnace is what to transition to, with way more SIDs supported. This means there is way more grouping of effects. CT is Cybertracker, OT is Odin Tracker, SIDW is SID Wizard. Compared to OPL3, SID is quite simple.

7x Select Chord (call chord table with 7F from arp table)
SID Wizard orderlist effects (GoatTracker apparently has something like this too):
xx Pattern number (00..7F)
8x Transpose -x+16 semitones down (F..0, somehow)
90 Switch off transposing (set original key)
9x Transpose x semitones up (1..F)
Ax Set main volume
Bx..FD Set track tempo (00..5D)
FE Song/sequence end, stop playback
FF Loop to the position specified after (<$80) or go to subsong minus $80 (>=$80)
Note: GoatTracker makes heavy use of tables, most parameters are indices to them.
Note: Defmon and Soundmonitor don't really use effect letters. There's a note delay column and 2 "sound program" columns in Defmon. Soundmonitor uses toggles for transpose, portamento, and arpeggio, in a somewhat cryptic way.
I'm not familiar with AY (see OPN SSG), SAA1099, POKEY, and software used to sequence music for them, so I won't be providing any effect table here, it would have just a Furnace column. Nintendo is boycotted due to no-life lawyers, for 2A03 see leftovers in Famitracker column. TI SN76489, VIC-20, TED and TIA are too simple for a special effect list, it's mostly about spamming their registers to achieve something even remotely musically entraining. ZX Beeper and PC Speaker use CPU-intensive modulations (rapid spamming) with software mixing.
An interesting endeavor would be to compile an effect letter азбука for use with Soviet computers. However it would probably end up like Impulse Tracker, with actual letters left for \xx, #xx, :xy, +xx, *xx, $xy and &xx. When trackers were becoming a thing in 1989, the Eastern Bloc and Soviet Union were collapsing, and everybody wanted western stuff like Amigas and PCs, even if it meant that they had to learn English and Latin. And the effect letters were originally hexadecimal digits, only some developers decided to use alphabet instead. Maybe there already is a fully cyrillic music tracker.
