Musicline r0x0rz but you better get some flash course on synths 101 or something, since setting up a sample is not as easy as loading it and playing with it (a la Protracker), you have to set parameters for the instrument, like the much important ADSR environment.
That's why I did not recommend it for newbies. It's a fucking AWESOME program, I tell you.
Rattus, dunno why you end up with a PDF file.. Are you using Screen Capture to snap your screen? Saves to TIFF for me here.
Someone should port something like fastTracker to the Mac. OH! The ONLY decent tracker on Mac is GoatTracker, the C64 SID tracker
Works a fucking treat.
