DESCRIPTION
DES-Tracker is a library system used for the playing
of tracker song modules. It is geared mainly towards
use in multi-media applications, but can be used in
virtually any type of application. DES-Tracker is
easy to install, easy to use, and includes lots of
example programs (with source code) that show how to
use the library to build applications on top of
DES-Tracker.
DES-Tracker works with all versions of the operating
system. It allocates audio channels using the audio
device, and tries to obtain the best possible CIA
interrupt timer.
FEATURES
1. DES-Tracker can load, save and convert between the
following tracker module file formats:
NoiseTracker v2.0
Protracker v1.1a
SoundTracker v2.6
DES-Tracker v1.0
2. Forty library functions that allow you to have
total control of the playing of a tracker module.
3. Complete signalling system for syncing music events
to application-related events. The DES-Tracker
library can signal an application whenever any of the
following events occur:
- A play sequence starts
- A play sequence ends
- The song is paused
- The song is un-paused
- A play sequence is aborted
- An iteration of the song completes
- A pattern finishes playing
- A volume fade operation completes
- A new song module is loaded
- The current song module is unloaded
- An application locks the library for
private use
- An application unlocks the library
- Each minute of play time elapses
- Each second of play time elapses
4. Over forty ARexx functions.
5. Allows you to specify start and end positions
within a song module either based on song position
or based on play time. Utilizes tempo and command
operand tracking to make sure that tempo is correct
no matter where in the song you start playing from.
6. Capable of calculating how long a song (or any part
of a song) will take to play. Can also calculate how
long a volume fade will take to complete.
7. Can load songs from disk or install songs from memory.
8. Includes a micro-jukebox program (with source code)
called "mJuke" that runs from the command line and can
play all songs in a specified directory. Can also
parse script files.
9. Includes a realtime scope program (with source code)
called "LScope" that monitors the player library and
produces a visual display with *proper* scopes, real
peak meters and lots of realtime information about a
playing song.
10. Includes a tracker module info program (with source
code) called "MODInfo" that displays all kinds of
statistics about any given tracker module (provided the
tracker module uses a file format that DES-Tracker
understands). This program is installed on the Wizard
Online BBS so that users can get all kinds of information
about a tracker module *before* they download (including
how long the song takes to play). MODInfo can also
detect and display sampletexts stored within a tracker
module.
11. Includes a CLI-based commander program (with source
code) called "DTC" that allows you to invoke almost all
player library functions from the command line. This
program also allows you to use DES-Tracker from within
Director II scripts.
12. Comes with include files for C and assembly language.
Also comes with pragmas and prototype files for SAS C.
13. DES-Tracker's library base structure contains lots of
useful information about the currently loaded song and
its instruments, as well as tons of realtime play info.
(Everything that the LScope program displays is done
solely by examining the library base structure).
14. DES-Tracker is freeware. This means that it is freely
distributable, but is *not* public domain. DES-Tracker
is copyright (c)1993 by Darren Schebek. Conditions
apply for use of DES-Tracker in commercial applications.
Please read the documentation included with DES-Tracker
for further details.
