prodatum Alpha 39

prodatum is a simple yet powerful free cross-platform preset editor, aka SysEx-editor, for the E-MU Proteus 2000 synthesizer family.
Written in C++, using portmidi for MIDI communications and FLTK for its user-interface, prodatum is available for Mac OS X, Linux, and Windows.
prodatum features some "hand-made" and optimized widgets like a Virtual Keyboard with range-sliders, an Envelope Editor with drag-zoom and a Master Monitor with control guarantee.

Main features:
- Intuitive editing by putting parameters into context where possible. For example: to set the transpose value for a layer you just middle-click the key on the virtual keyboard that should play middle-C.
- Quick-edit: You turn a knob and thats it; there is no explicit saving needed and you can switch presets back and forth without losing any data ever.
- Undo and Redo
- Preset parameter cache: Makes preset-switching a breeze once data has been cached.
- Utilities: Copy presets around randomize presets or manage (load/save/rename) your multisetups.

Enhancements
- improved piano drawing and master monitor drawing (implicit outlines, to save some CPU cycles)
- added an about tab
- always close portmidi on exit. this hopefully fixes prodatum hanging on exit as some experienced
- bug: when you selected a different instrument for layer X, then switched to layer Y, then pressed "Undo" for layer X, the layer button didnt update the instrument name. fixed
- code cleanups
