After a really long time doing other things, I've finally decided to adapt another version of GoatTracker for Mac OS X. Many things have changed and GoatTracker has definitely matured into a state-of-the-art C64 music editor. This time around, the Mac OS X integration is much more complete, offering standard keyboard shortcuts, built-in help windows, and open/save dialogs for songs and instruments. There's more room for future improvements though. If you're actively using GoatTracker, please let me know of any ideas and suggestions you might have.
