- Just a quick question-and-answer file.
-
- - What is tracker, what do I need to use it ?
- tracker is a generic soundtracker player for unix-like machines.
- You need an amiga or a sparcstation or an siligon graphics iris,
- or a PC with unix and soundblaster, or a DECstation, or an HP700...
- Your machine should be able to produce sounds, that goes without
- saying. You also need tunes to play (mod files). Some are available
- on nic.funet.fi, for instance.
-
- You will also want to get zoo and lha for your machines.
- They should be on nic.funet.fi or aminet.
-
- - How to compile it ?
- The Makefile should be self-explanatory. Mostly you need to set it up
- for your machine. The sparc/solaris target depends on which version
- of sunos you've got. You will notice if you set it up incorrectly.
- Right now, solaris is still a mess, so some hacking around might be needed.
- For the amiga and SAS/C, a smakefile is provided.
- There are still some obscure problems with NeXt and other machines...
- I can't check everything myself, so you might just be on your own in some
- cases.
-
- - How to use it ?
- tracker -help will give you a good idea of what's available.
-
- - How does it compare with SparcTracker, or str32 ?
- Well it's better... No, actually it's the same program, but the name has
- changed as it was evolving. So anything labelled SparcTracker100,
- SparcTracker1.1, or sparctracker1.2 is OLD. Don't send me any bug reports
- about these older versions, this is useless. Well, I'll try not to change
- the name of the program again...
-
- - How does it compare with other trackers on the amiga ?
- First, its interface is not very friendly.
- But then, its source is in C, so it's easy to fix what you don't
- like, and it should get better over time. Also, it plays entirely by the
- rules, so it should work with any foreseeable releases of the OS, or even
- with audio cards that patch the audio.device in a reasonable way.
- However, there is more to it than meets the eye. The way tracker works is
- rather more intricate than most other players, and it should solve most
- timing problem in a rather elegant way.
-
- - Which kind of modules can it play ?
- MOST soundtracker/noiseplayer/protracker modules should play out ok. Due
- to various disagreements between all the soundtracker versions (never forget
- soundtracker is an horrible HACK, a big KLUDGE), it is a *REAL* nightmare to
- try and make some commands work. What you have is my best effort at trying
- to outguess every soundtracker composer in existence... Obviously, I haven't
- completely succeeded. MED support I've thought of, but don't forget, to
- make tracker work, I need to reverse-engineer assembly routines coded like
- spaghetti, and transform it into more or less human-readable, normal C code.
- So up till now, I haven't had time enough to do the same with MED. Teijo's
- code is not exactly limpid, MEDplayer itself tends to change from release to
- release. So maybe one day...
- Here is what is missing from the protracker format
- * extended commands 3/4/7/13/14
-
- Actually, if you know other player programs, you will notice that tracker is
- better at that compatibility game than most of them, like <BLIP>, <BLOP> or <ZP>
- (names intentionnally omitted:-) )
-
- - What are these weird things scrolling on my screen ?
- These are some informations on the current module, like its name,
- the distinct sample lengths and their names.
- Oh, you mean -scroll ? Well, this is the tune being played. Get any protracker
- doc, I think you'll understand what's going on.
-
- - I can't change the volume of the sound.
- That's intentional. There are other programs that do that quite well.
- What you really want is an audio control panel. There are some nifty ones
- around, just search carefully. There is no real need for tracker to support
- variable
- volume.
-
- - There are some ``not supported'' messages from time to time.
- tracker doesn't support the whole set of protracker commands, so it tells
- you when it doesn't play something the way it's supposed to be played.
- I don't know if I'll implement the remaining commands, as they are symptomatic
- for me that the mod format is just a big kludge, and not getting any better...
-
- - I want to use tracker on another machine.
- Then you'll have to port it. You can wedge in at two levels: either replace
- the audio.c file or the xxx_audio.c. The audio.c works at the amiga level:
- it interprets commands to play samples and repeat parts in terms of
- resampling them at the right frequency. If your machine supports four fully
- independent channels (like the amiga), you shouldn't have to resample, but
- instead issue the proper commands for these samples to play.
- Else, you'll have to use resampling, and going through a specialized xxx/audio
- file. The examples you have should be quite enough.
- If your unix is funky enough, define your machine to use stubs in Unix/ui.c
- at first, then try to get it back into action...
- If you make tracker run on another machine, please send me the required changes.
- Try to keep it to the audio.c xxx/audio.c and xxx/ui.c file If you make any
- other enhancement, I might like to incorporate it in a further release, but
- that part of the code may have evolved beyond control in between. xxx/audio
- files I can grope !
-
- - How do I know which version I have ?
- Look at the version strings embedded in the various source files, and into
- the program itself. The highest one is the winner (usually the one from
- main.c).
-
- - What's going to happen next ?
- <from v 3.19>
- Porting tracker back to the amiga was very insightful. Even though I didn't
- have to change the source much, I now have lots of ideas about things to add
- and change throughout the whole source. The next version will probably be
- sturdier, easier to modify, and it will probably possible to hook a real
- graphic interface somewhere. Also, I intend to implement better recognition
- of various variants of the tracker format at some point, and even MED support
- maybe. There will probably be some interface to sox in the near future, plus
- some sturdier tools to read modules, extract samples from them, and compress
- them better (using gzip/lha/zip to compress the module part, and shorten
- for the samples part).
-
- Well, the code IS sturdier and easier to modify now, and the amiga version
- features a fully graphic user interface. I don't intend to add an X window
- interface to the unix version in the near future as I don't have the time.
- However, all the hooks are there, so if you want to do it, go ahead.
- Recognition of Med format files still turns out to be a rather nasty problem,
- especially since there are so many incompatible MED formats, and so little
- documentation. Tikkunen is a good programmer, but a poor doc writer...
