The Music Editor.
Radium is a music editor with a new type of interface.
Compared to the normal sequencer interface editing is quicker and more musical data fits on the screen.
Compared to trackers, note positions and effects are edited graphically, which should be quicker, provide more vertical space and give a better musically overview. (Everything can also be edited by text, like in a normal tracker)
Radium can also be used as a normal multitracker. (I.e. ignore the note editor part of the program) However, despite its unusual appearance, it's a design goal for Radium to be straightforward to use, and easy to learn. It should not be harder to learn Radium than any tracker or most MIDI sequencers. Users accustomed to trackers might use more time adjusting to the interface.
