@Johan: Looks interesting... great. It would be even greater, if you could supply us with more information on how to obtain this USB device and where can one get the special DosBox version for download... I would then put all this stuff to FAQ section. ;)

Johan, opl3-geek from Netherlands. Wednesday, 30th December 2015, 15:44


did you know you DON'T need old hardware to get opl3/adlib support :)
there is a device on USB with expansion boards with yamaha chips.
check this out: https://youtu.be/9HjqZp9uLwY

link to the site: http://gimic.net/index.php?Getting%20Started%20with%20G.I.M.I.C

i use a special edition of dosbox to use the OPL3 on adlib tracker 2 :)

@Ludd: You can try installing DOS, but I barely believe that soundcard's driver will give you better results with OPL3 emulation than SDL verion, even if you will be able to make it work. Some notebooks are simply not suitable for AT2 in any aspect - if they are yet (HW-wise) too old to decently run the SDL version, and they are already not containing real OPL3 chip, this is the case then :-)

Ludd, newbie from Argentina. Sunday, 6th December 2015, 9:31

I tried the SDL-Linux version. It sounds right but glitchy and overloading the ram (just 144 mb).
So, the SDL-version does emulation of the OPL3 by software, right?
Does the NeoMagic soundcard must do emulation of OPL3 stuff by hardware in DOS native system? It make sense if I try installing DOS for that?
Is FreeDOS good?

subz3ro, coder from Slovakia. Saturday, 5th December 2015, 18:29

@Ludd: My Gateway Solo 2500 notebook uses NeoMagic NMA 2 and it handles OPL3 stuff very fine, but it is an ISA bus card. From what I was able to find, it seems that this your NeoMagic 2200 is a PCI bus card, and only uses AC97 codec. What you can try is using SDL-Linux version and see how it will perform on this "older" hardware...

Ludd, newbie from Argentina. Friday, 4th December 2015, 0:29

hi people,
i have an old laptop with linux debian installed:
Dell Latitude CPi A366ST. Sound Controller: NeoMagic nm 2200 av. "Soundblaster compatible".
Do you know if AT2 will work?

@Jalex: I don't have any experience with Mac's and their operating system, so to current moment, it's not planned from my side. But as recent version is pure Free Pascal Compiler except this one C module for emulation of YMF262 chip, I think it should be possible to compile it for Mac OS X too, as SDL library is available for this platform, and so is available GCC, which means it's just question of simple code change (adding compiler directives for Mac OS X, which could be mostly the same branch like for Linux) and compiling... which means something, that should be really no big deal for anybody (with basic or medium knowledge in programming) who owns computer with Mac OS X :)

Jalex, musician from Russia. Tuesday, 27th October 2015, 11:51

Hey ! Thank you for your work. Great tracker. Just one question: OS X version it's possible? Yeah I know about dos box))) it's just fetish, native OS X version.

Hello, just wanted to say that it's great when you develop programs like this. It's important to keep FM synthesis alive! I'm especially interested about old DOS games that use FM synthesis.

@David: Don't know if it's his real name, but he distributed this track on Youtube under account Roger Ojala. (check out here: https://www.youtube.com/watch?v=meGu4RkiWT8)

David, newbie from UK. Monday, 12th October 2015, 16:23

Does anyone know who did the track 'Square' in the modules folder? it is amazing but I don't know who the artist is!

subz3ro, coder from Slovakia. Saturday, 10th October 2015, 16:02

@David: No need to thank, I'm glad to implement reasonable and useful feature requests -- and this yours is very good example ;)

David, newbie from UK. Saturday, 10th October 2015, 3:31

@subz3ro Thanks very much I will check the downloads section over the next few weeks. I really appreciate you thinking about adding the feature!

subz3ro, coder from Slovakia. Thursday, 8th October 2015, 19:10

@David: Ok, this sounds feasible... even though Ctrl+1..8 keys are already occupied by setting of octave, so perhaps it will be Ctrl+Shift+1..4 for triggering mute on operators. I will make beta version when this feature is done, so check the bottom of Downloads section from time to time ;)

david, newbie from uk. Thursday, 8th October 2015, 2:33

>I'm not certain what you mean with muting operators.... setting operator's volume temporary to 0?

Yes, that is right! The feature is described on page 7 of the dx11 manual as 'operator on/off'


I imagine a toggle where while on the instrument screen :

ctrl + 1 sets OP1 output level to 0 / pressing again returns it to the original output level.
ctrl + 2 sets OP2 output level to 0 etc

This makes it a bit easier to for example just work on one pair of operators when making a sound or to turn off the modulators so you can get the carrier envelope just right.

@David: I'm not certain what you mean with muting operators.... setting operator's volume temporary to 0?

David, newbie from UK/Japan. Wednesday, 7th October 2015, 18:13

Thank you very much for taking the time to answer my questions. I feel I understand the macro editor a little better now. I am working on my first song.

I have a small request. Would it be possible to add a shortcut (or 4 shortcuts I guess) to mute operators on the instrument screen? When programming the classic yamaha keyboards, there was an option to do this which I found very useful when programming 4op instruments.

If this isn't possible I totally understand but thanks for reading!

subz3ro, coder from Slovakia. Monday, 5th October 2015, 21:41

@Lazerbeat: Here are the answers to your questions...
1) Yes, song speed gives the number of frames (or timer ticks as you say) available for processing of pattern effects
2) Not necessarily... it's true only if you leave macro speed up factor at default (x1) value... if you increase the speed up factor, the macro timer value is increased compared to song (pattern) timer value, so there are more macro rows (or lines as you say) processed per one row in the pattern.
3) Yes, but to be precise, the macro rows in FM-register table are not repeated, but advancing to next row in the table is delayed... this means, FM-registers are written only once to the OPL3 chip, at the beginning of the "duration" cycle. In principle, "duration" in FM-register table has the same meaning like "speed" in Arpeggio/Vibrato table, but it can be different for every row of FM-register table, while "speed" is common for complete Arpeggio/Vibrato table.
4) It is the same. The difference is that you can slide the frequency more quickly, if necessary, compared to pattern effects 1xx/2xx, which is especially useful for making drums in songs with higher speeds, as this wouldn't be possible with 1xx/2xx effects.
Hope that helps.... good luck with the macro instruments ;)

Lazerbeat, newbie from UK/Japan. Monday, 5th October 2015, 17:42

Hello subz3ro I have some questions about the macro editor. It seems very powerful but a little hard to understand!

1 - Just to confirm I understand, in the song variable screen, does 'song speed' decide how many 'ticks' there are per line in the tracker?

2 - Again to confirm I understand, if the song speed is 6, then 6 lines of the macro editor execute each line in the tracker, is that right?

3 - Does duration control the number of repeats each line in the macro editor executes before moving on to the next line?

4 - how is the freq slide in the macro editor different to the 1xx / 2xx commands? 1xx / 2xx have two values but the freq slide is - or + xxx so there are 3 values.

Thank you very much for taking the time to read this, I hope to start making interesting macro instruments soon!

subz3ro, coder from Slovakia. Friday, 2nd October 2015, 12:03

IMHO, having a genuine YMF262 chip onboard is still no warranty for accurate FM sound. Example is this SB 16 Vibra PnP /CT2890/ sound card (http://mail.lipsia.de/~enigma/neu/pics/soundblaster_vibra16s_ct2890.jpg) which has the genuine OPL3 chip from Yamaha assembled, but the sound is really crappy due to some misstep (?) in DAC design :P
What I can recommend you is that you should try to get SB 16 model CT2830, which fulfills your requirement for having YMF262 chip (if you insist on having it), and produces really nice FM sound with very deep bass ;) If you won't insist on having the chip from Yamaha there, I would advice you to go along with any of the CT1747-equipped SB cards... :)

Matej, musician from Slovakia. Thursday, 1st October 2015, 12:01

Hello friends.

I want to buy Soundblaster 16 ISA with real YMF262. Or PCI compatible soundcard with real OPL3...
I have 18 ISA soundcards but no one is with real Yamaha chip.

I am from EU.

@Monochromatism: You have a few options, none of them simple or very user friendly:

1. The VGM file format supports YM2608 data. However I know of no trackers supporting the YM2608, which means you would have to directly write processor instructions in the VGM format.

2. You can use a pre-existing sound driver that supports it, such as PMD (https://sites.google.com/site/kajapon/), FMP (http://guu.fmp.jp/archives/493), or Mdrv2 (http://www.vector.co.jp/soft/dos/art/se018677.html?_ga=1.32624829.241947326.1436475269). These are all in Japanese, and mostly need to be run on the original hardware or emulation to work properly. They do not have trackers but MML compilers, so you need to learn each driver's MML implementation to compose songs. PMD is the easiest sound driver to use as far as I know, and it is the one I use.

On my Youtube channel I have links to a partially translated PMD MML manual, as well as songs with example code: https://www.youtube.com/channel/UCy8BkjyCMaTNs0Q9KCZzXjg

Good luck, and I would be happy to help with anything else.

subz3ro, coder from Slovakia. Monday, 21st September 2015, 10:40

@Monochromatism: No, unfortunately you don't have correct information (redirection). AT2 is no tracker for Yamaha OPNx chip family, but for Yamaha OPLx, particularly YMF262 (OPL3).

Monochromatism, newbie from America. Sunday, 20th September 2015, 23:53

Hey, I was directed to this program by a forum post claiming this to be a solution to someone's need for a YM2608 tracker. You know, to make authentic PC-98 songs. I have no idea what I'm doing, but I'd like to learn.

Would what I'm asking be possible? Am I just being an idiot? I'd gladly pick up any other resources I'd be required to.

subz3ro, coder from Slovakia. Tuesday, 8th September 2015, 19:03

@dg: Congrats to finding yourself correct path through the FM-operators :) As to your questions about macros, this is a longer story to tell, and surely out of the scope for this message board. I would kindly ask you to join the user group on Facebook (https://www.facebook.com/groups/325024534342356/) where such user topics and experiences are discussed. I'm sure you will get answers to your questions there.

dg, newbie from uk. Tuesday, 8th September 2015, 15:28

Worked it out. Push ctrl+i to get into instrument editor, then push tab to see instrument settings, finally the ENTER button switches between operator 1 and 2. In FM mode you can tell which one is op1 or op2 by the checking whether the feedback section is highlighted or not.

This program is not very noob friendly but it's really great once you've worked out how to do things. Making up BDs (255), snares, hihats, pads, basses, bells, detuned layered pads is AWESOME.

Haven't done anything with macros yet. Can they be triggered with each note-on to cycle through a selection of notes and effects? I'm looking to cycle through parameters each bar, adding randomisation so that each time the 4 bar pattern plays it is slightly different.

For example, using pitch down effect on a bass drum of 255, can I make it so the effect chooses randomly between 240 and 270 each time the bar plays?

Also can I do automated note replacement?

.(E5 or G5 or A5) chosen at random
.(B4 or D#) chosen at random

From what I can see, macros are triggered by TIME not triggered by note-on. Right or wrong?

Thanks for your help and thanks for the great software. It is truly amazing. <3 FM synthesis.

BTW is it technically possible to run more than 1 OPL3 card on your PC in msdos?
Is it feasible to have 2 soundcards for 36 channels? 3 cards for 54 channels? 4 cards for 72 channels of FM goodness? (external mixer required of course)

subz3ro, coder from Slovakia. Sunday, 6th September 2015, 16:41

@dk: You are probably not looking thoroughly :o)

dg, musician from uk. Saturday, 5th September 2015, 2:59

There's only a setting for 1 envelope in the ctr+i instrument manager! Shouldn't there be settings for 2 ADSRs? 1 for carrier 1 for modulator?

FreeFull, another visitor from England. Friday, 31st July 2015, 1:01

Well, I'm not the one who named the file, it was in an archive of songs =P
255 bytes should work, since it's the max filename length on NTFS and the usual Linux file systems.
I can see how any bug relating to case sensitivity would be missed, since Windows and DOS are both case insensitive. Thanks for looking into it!

subz3ro, coder from Slovakia. Thursday, 30th July 2015, 11:43

@FreeFull: You often use such naming conventions for song filenames? *LOL*
Anyway, there was a limit set for 80 chars for filename in SDL version line (never thought anybody would name songs like that, though), so I set it to maximum (255 chars) now. As for the case sensitivity-related issues, this needs some more analysis from Linux maintenance specialist (Insane/Altair), I have to ask him.

FreeFull, another visitor from England. Thursday, 30th July 2015, 4:36

On Linux, AT2 refuses to load music files if the file extension is in uppercase, but works fine if it's lowercase. (The files get shown in the file selection dialog, but when selected and enter is pressed the dialog closes and nothing else happens)

Also, if the filename is too long, it won't show the extension in the file open dialog, and will refuse to open it either. An example filename with which this is a problem is:
(dlz-mind)-BBS INTRO Apollo-X Demo Resources Webpage, by Seffren-DF2 and Dalezy-DF2 (1999).amd

ijsf, opl3-geek from NL. Thursday, 11th June 2015, 15:02

@subz3ro: Understood, no harm done. I think a good compromise is that the SYNTH! version is still up for download :)

Who knows, I might reimplement the feature some day. In an ideal situation AT2 would be used to help chip musicians out there to get some real OPL3 back in their productions without too much hassle.

subz3ro, coder from Slovakia. Thursday, 11th June 2015, 11:08

@ijsf: I see I have to express myself in more words to overcome some confusion :) Main reason to remove it was the code merge between DOS/SDL version, and the fact that it was only done for DOS version, while I was not able to manage the new features involving classic MBOARD mode (and keybord in general) usage and test possible interferences with SYNTH! mode. Also, some UI space / shortcuts had to be handed over to NREC mode. That's why, you know :) But the user feedback was the trigger, and I was really getting sick of not able to answer questions why this-and-that on this feature :) I hope you don't mind too much, bro. Still, was hell of good effort from your side - and only one (ever) feature done for Open Source by somebody else. I wish there was more stuff like that :)

ijsf, opl3-geek from NL. Thursday, 11th June 2015, 2:12

MidiSynth was pretty much a hack in order to use AT2 standalone acting as a synth with a DAW. Shame it has been removed, but I can understand why.

By the way.. I just built a AT2 PC setup with likely the best possible quality OPL3 out there. I'm running AT2 with a Yamaha YMF744 chip (AOpen AW744, PCI sound card) which, AFAIK, is one of the last OPL3-compatible chips ever made from Yamaha itself with possibly the best signal-to-noise ratio out there, as well as SPD-IF digital output. Works flawlessly and therefore seems like a perfect match for a high quality AT2 setup!

fede, another visitor from argentina. Tuesday, 9th June 2015, 21:26

great, thanks. by the way, is there a key combination to fullscreen the sdl version under linux? Thanks!

subz3ro, coder from Slovakia. Tuesday, 9th June 2015, 16:22

@fede: There was some simplified use of MPU401 done as a feature (called MidiSynth mode) by one member a few years back, but it's been removed due to no good user feedback to it. However, you can try it with DOS version 2.3.52 which is still available in the Downloads section.

fede, another visitor from argentina. Monday, 8th June 2015, 1:33

I just found out according to the revision history there is a MPU-401 mode in the dos version, but I can't seem to find how to activate it. I have my midi keyboard connected and working with other trackers, though. Thanks again!

subz3ro, coder from Slovakia. Monday, 25th May 2015, 22:10

@d13f00l: Hmm, good point. Never thought of being necessary to set it for standalone player too. Will improve this in next version.

d13f00l, coder from USA. Wednesday, 20th May 2015, 3:58

Ok - setting OPL_LATENCY in the INI file does work, but only for the tracker, not the player!

d13f00l, coder from USA. Tuesday, 19th May 2015, 10:34

Having trouble with ADT2PLAY.EXE - Try an A2M file - it freaks out after a few seconds. Happens with two different sound cards with the hardware chip. It's win98 7.1 dos, but booted straight to dos.
If you do try it, please queue a sapi midi after to stop the horrible noise...

cyandyedcyanide, opl3-geek from Magna Frisia. Saturday, 9th May 2015, 19:08

Hey guys, I made a subreddit for Adlib Tracker! There's nothing there yet, but with your help we could turn it into a nice place to post your best tracks and share your favourite FM tricks. Check it out: http://www.reddit.com/r/adtrack2/

ToriH, another visitor from netherlands. Tuesday, 5th May 2015, 20:29

Ok thanks for the info, i meant indeed the amount of actual used data in existing modules. I will take a look in the Song Variables window.

subz3ro, coder from Slovakia. Tuesday, 5th May 2015, 16:31

@ToriH: Don't know if I get your question in correct way.... as either you might want to know how much of this data is used in some of the existing modules you want to port/convert, or you want to hear some procedural description how to do this in any module. For the first case, I would refer you to Song Variables window, where this information is always visible. For the latter case, this is not possible to describe easy, but if you have some level of knowledge in Pascal, it's very easy to distinguish from the source code - just refer to procedures "count_order", "count_patterns" and "count_instruments".

@Darkhog: I suppose you are member Dariusz G. Jagielski from AT2 user group on FB, so all the related points/answers are already there....

Darkhog, newbie from Poland. Tuesday, 5th May 2015, 0:38

Any chances for "proper" win32 port of adlib tracker? I mean with menus and easy interface, preferably similar to either FamiTracker or OpenMPT?

ToriH, another visitor from netherlands. Sunday, 3rd May 2015, 23:16

Hi, i'm trying to port the .a2m module format to a platform with just a limited amount of memory (for replaying only). For that i'm looking for a way to keep the module as compact as possible when saving i.e. put only in the data that is actually needed. For a number of structures this (like the macro_table) this is easy since it contains a length attribute, this already saves up to about half the expanded file size. Is there an easy way to determine the number of actual used data like instruments and instrument macros as well?

Btw: I think you did a very great job with this program!

maggan, musician from sweden. Sunday, 12th April 2015, 9:13

your program is awesome!
