writes "According to PlayerPROLounge, the source code for PlayerPRO, the $69 professional tracker-based audio application for Mac OS & Mac OS X, has been released due to the developer's inability to continue the project full time. The software, currently at version 5.9.5 is fully matured, but needs optimizations for Mac OS X. If enough interest is garnered, a SourceForge.net project will be started. Any takers?"
No word that I can see on what license is used.
