Updates include:

"Another customization that you may want to tweak is the keyboard mapping. The default layout maps about two and half octaves for the QWERTY alphanumeric keyboard, but there are some more definitions in the data directory, adapted for other international layouts. You can even define your own mapping using a dialog box available in the Edit->Keyboard map menu. There are also options to load and save the maps as XML files. The last loaded map will be remembered the next time you start VMPK. In fact, all your preferences, selected MIDI bank and program, and the controller values will be saved on exit, and restored when you restart VMPK the next time."

"Scala is a powerful software tool for experimentation with musical tunings, such as just intonation scales, equal and historical temperaments, microtonal and macrotonal scales, and non-Western scales. It supports scale creation, editing, comparison, analysis, storage, tuning of electronic instruments, and MIDI file generation and tuning conversion. All this is integrated into a single application with a wide variety of mathematical routines and scale creation methods. Scala is ideal for the exploration of tunings and becoming familiar with the concepts involved. In addition, a very large library of scales is freely available for Scala and can be used for analysis or music creation."
