Here is the latest release candidate of the Minitaur Editor software for OSX and Windows.
I have tested it on OSX Lion and Windows 7 (32 and 64 bit). Everything that is implemented seems to work.
Note that this is not a plugin but a standalone application. It does not currently pass-thru or merge MIDI from multiple sources, so it does not work in conjunction with your sequencer/DAW software to provide automation or anything like that. It lets you create, save, and load presets, and gives access to all the non-panel parameters. And it's free.

Windows users: presets are organized within the data/presets folder; you can create new category folders here and they will show up within the Editor.
Mac users: to access the preset and category folders you must control+click on the Minitaur Editor icon and choose "Show Package Contents." Presets are located in the Resources/data/presets folder. You can create new category folders here and they will show up within the Editor.
here are the downloads:
http://seamslikereality.com/moog/Minita ... 12_OSX.zip (mac)
http://seamslikereality.com/moog/Minita ... 12_WIN.zip (windows)
To get started, simply unzip and launch the Minitaur Editor.
You will need to show the Under The Hood window (on the View menu, or CTRL+2) and select a Midi Input and Midi Output. Usually, this would be Moog Minitaur. If you connect the Minitaur's USB to your computer after you launch the MInitaur Editor, you may need to click the REFRESH button in order for the Minitaur to appear on the list of MIDI Inputs and Outputs.
If you have any questions or comments, please post them here. Thanks!
