NAME
       loadtracker - C64 music editor

SYNOPSIS
       loadtrk [songname] [options]

DESCRIPTION
       This manual page documents briefly the loadtrk command.

       loadtracker is a C64 music tracker derived from goattracker.  It
       supports emulated output via the software reSIDfp engine or the exSID
       soundcard, and produces songs in its gt2 format (*.SNG).  The program
       can also export tunes in SID format, BIN format, or Commodore PRG
       format for inclusion on a floppy you can stick into a 1541/1571/1581
       drive.

       Like most tracker programs, the program is able to import instrument
       files, create and modify track patterns, set the order of playback of
       patterns and change details of the song such as the title and author.
       If you are familiar with tracker-like programs, then LoadTracker will
       feel like a simple version of those, though with differences
       attributable to the hardware. People new to composing in general should
       look up other information on composing on the C64.
