Microtuner LE

From Victor Cerullo:

Microtuner LE is a Windows utility for creating and editing microtonal scales and keyboard mappings derived from a similar Macintosh application called Max Magic Microtuner; with this program you can create, import, edit and export 128-note MIDI Tuning Standard keymap files (.syx, .mid) compatible with the Native Instruments FM7 softsynth and with all software and hardware synthesizers supporting the MTS format; you can also import and export native Scala (.scl) microtuning files, export Korg OASYS PCI audio card tuning files (.tun), and export Native Instruments Pro-52/Pro-53 tuning files (.p5m). The features of Microtuner LE for Windows are identical to the features of Max Magic
