Notes for Windows integration 
Adding keyboard shortcuts to Windows
You need to install the SelectedTrackControl MIDI Remote Script.
To turn you computer keyboard into a MIDI-controller just like Kimidi does on Mac OS X, Bome’s Midi Translator Pro should be a good starting point. If you have created a configuration for it (or have another solution for turning keyboard input into MIDI on Windows) I would be happy, if you share it.
