SparcTracker ver. 1.2 by Liam Corner and Marc Espie
===================================================
NOTE! This is an old and obsolete version. The latest version is
called tracker-3.19.
#ifdef linux
This version contains some minor modifications for Linux by Hannu Savolainen
(hannu@voxware.pp.fi) and Leif Kornstaedt (l_kornst@informatik.uni-kl.de).
Have a look at the options in the Makefile (e.g. the -m486 option) and at
the str.h header file, in which you may configure some things.
Please edit DSP_SPEED in the file str.h before compiling. The default
setting for output frequency is 23 kHz, which may be too fast for 386/386sx
machines. At least you have to change it if there happens to be short
pauses in playback.
#endif
Well, here they are the first tracker module players for the Sun
Sparcstations. There are 2 players, one for the 15 sample modules and one for
the 32 sample ones (or should that be 31 :-). The code is not that different,
but I could not be bothered to write an auto detection routine that worked on
standard input.
Usage
-----
Usage is very simple, either give the player the filename of the module, or if
the module is compressed(frozen) you can zcat(fcat) and pipe the result into
the player thus :
str32 -h
str32 [options] module ...
zcat module.z | str32 [options]
fcat module.F | str32 [options]
If you have a new module and are unsure of which player (str15 or str32) to
use then try both. If you choose the wrong one then you may get an error
message or nothing at all will happen (except maybe a core dump :-). For
this reason I keep my trackers in separate directories so that I know which
player to use.
Not many effects are implemented, so the result may not be exactly the same as
an Amiga player, but it is usually OK. The sound quality of the /dev/audio is
not too hot, so some sounds are lost, usually the bass.
Options
-------
This version acceps several command line options:
-s kHz Sets the playback speed. For example
str32 -s 20 plays the module with
22 kHz sampling frequency.
-S Plays the module in stereo.
-c Non-stop mode.
-q Quiet.
-b bits Sets the sample size (8 or 16 bits).
-o file Redirects output to a file or
another device.
Errors
------
The only error not totally self-explanatory is the 'corrupt input file' one.
This sometimes indicates that you have used the wrong player, but
occassionally it may be that the module is too short by a few bytes. I have
only come accross this in a couple of cases and just appending a few null
bytes to the end usually cures this.
The Future
----------
I may get around to combining the players into a single program and enhancing
the error detection a bit, but then again I might not :-). If anyone else
wants to add these functions, add more effects or correct any errors there may
be in the current programs then please go ahead - I hope the code is
understandable enough for you.
Copyright Stuff
---------------
Most of the code is copyright me. The convert routine is copyright Rich
Gopstein and was borrowed from the iff2ulaw utility. The code is freely
distributable as long as this message and the copyright messages in the source
are included. You are welcome to update the source code.

Version 1.2 - 3rd November 1991
-------------------------------
Thanks to Marc Espie for doing most of the first update. There is now only
one player str15 and a link from str32 to str15, so you will still have to
choose the correct player for a given module. There is now output showing
module name, sample names and progress through the module as it plays. More
effects are implemented and a bug with the sample repeat loop has been fixed.
Patch 08/27/92 by Hannu Savolainen
----------------------------------
Modified to use integer arithmetic.
Version 1.5 - 31st January 1993 by Leif Kornstaedt
--------------------------------------------------
- Now all standard NoiseTracker 1.0 effects should be implemented correctly,
as well as some bugs fixed (and the step_table calculations more accurate).
- Some command line options have been added, namely:
-v verbose: the score is shown while playing
-z zcat is applied to the files before playing
- You can now give a default path to search modules when they are not found
in the current working directory. E. g. using /bin/bash do
$ export MODPATH=/usr/local/lib/mod/tracks15:/usr/local/lib/mod/tracks32
TODO:
- automatically determine the number of instruments instead of having
str15 and str32 (by testing 'M.K.' sig)
- insert a shuffle mode: let the player play all songs in the module
path, but shuffled like a CD player does.
Please let me know if you find something to ameliorate. -- L. K.
