Futucraft has announced version 1.2 of Kairatune, a free synthesizer instrument for Windows and Mac.
This update adds native 64-bit support for Windows users and makes Kairatune available for Mac users for the first time. The OS X version supports both 32-bit and 64-bit Macs and is available as Audio Unit instrument as well as VST instrument.
Kairatune 1.2 has a completely redesigned preset manager, offering support for unlimited number of presets and the possibility to add, copy, paste and remove individual presets and the ability to add metadata, such as preset category, which you can use to narrow down the list of presets while browsing for the right sound, and metadata such as the preset author with contact URL and more.
However, most of my work has been under the hood, redesigning and implementing the inner workings of this plugin. Some of this is because the expansion to OS X, and some for even better sound and user experience i.e. for performance, stability and smoother overall action.
Kairatune is available to download for Windows and Mac (VST/AU) as freeware.
