To run Synthclipse you need:
Synthclipse runs on all three major desktop Operating Systems:
but Audio Player currently works only on Microsoft Windows and on Linux. I am not able to port it to the Mac OS since I do not have Macintosh.
You can download the latest version (0.9.9) from Synthclipse's SourceForge website. Remember to chose proper version for your Operating System and CPU architecture.
Installation is very simple. Just extract downloaded archive and run file eclipse.exe (or just eclipse depending on your Operating System).
