Radium is an open source music editor with a novel interface. It's inspired by trackers, but has fewer limitations and uses graphics to show musical data.

(Did this because of bad performance with QT4 2D graphics. The editor now runs as an embedded widget in QT4.) * More colorful default colors * Various build fixes * Compiles under MinGW. (Tested in wine and Windows7, but it doesn't work very well yet.) * RELEASE buildtype. * Fix nodeline selection * Antialiased lines * Adjusted tempo colors * Fix race condition for midi input * Midi input editing. * Removed the custom resize window box. * midi: increased latency from 1.95ms to 5ms. (This should probably be configurable) * Various bug fixes and improvements
