Not a lot of FREE programs that can host VST Instruments, eh? Well, this is one and does it better than I expected. It's not pretty, it's not easy, it's still pretty awesome though.

5.3.25 is the current version, with a creation date of December 19, 2013. You'll find this version number listed in the 'What's New' list above. I think it is well past time MacUpdate ditched the '3.0' listing on this page. *Please*

Note that this application is NOT compliant with Apple's user experience guidelines. It looks like a Linux application, although it is only available for Mac and Windows. Therefore, it takes a bit of getting used to with ALL the controls/menus being inside the application window. There is nothing available via the Mac's menubar, which only lists the application name.

It can be used with or without a MIDI device attached. It has a huge selection of personalization features. For free, it's terrific! But be prepared to climb the learning curve.

Even though I currently use purchased sequencers such as Live and ProTools I think it's great that a company is offering even a limited version for free. My only request for the free version would be to add rewire even in a stereo form. Prior to owning my current software i looked around endlessly for a free app that can do what luna does + rewire.
