[LAU] Harmony Tool for Composition (part 1 of 2)

Almost a decade ago I was using Jazz++ for my MIDI sequencer and composition tool. That project rolls over in its grave from time to time, but I consider it dead. I've been very happily using Rosegarden4 for everything that Jazz++ used to do for me, almost, and I like Rosegarden4 much better. Now for the "almost" issue. Jazz++ has a feature which it called a "harmony browser" which allowed me (a drummer) to explore chord structure and musical modes when writing a tune. I haven't found anything else that has this ability. Maybe one of you knows something about this? I don't know if it's OK to attach pictures or not, but they're really tiny so I'll take a chance. The hbtoolb.gif file shows how Jazz++ allowed me to select which types of chords I wanted to explore by clicking the gray boxes near the top of the window. The hb.gif file (in the next message) shows various chords, of the selected type, in the various modes. In Jazz++ I could click on the chord names in the boxes and get to hear what they sound like. I *really* want to have a tool that lets me do this again. Any ideas folks? Thanks much... -- Kevin
