The Fairlight CMI was a game changer and QasarBeach is a great recreation of this instrument. However, there still all too many bugs and issues that render it a non-usable tool for a production environment. E.g. no VST/AU/CLAP version, can't manage multiple audio channels properly or even choice what audio interface to use, there is no aliasing filter for escalated graphics (it looks really UGLY if the resolution of the window is not a perfect multiple of the original screen), etc.

However, the author is improving the application continuously and I am pretty sure it will be a perfect Fairlight in a near future.
