Interesting thread. I've been getting ready to do some music writing, recording and editing also. Have accumulated some gear including a good keyboard, but not have things hooked up to pc yet, until I finish some other chores and projects. But will subscribe to this thread for updates, and share info when I have more.
I reviewed a fair amount of music software products for home desktop pc before buying a mid-level pkg or two. Also have Digi-design's trial version of Pro-Tools, but not knowledgeable enough to use it yet. Just poked thru it's windows & some menus etc a while back.
Have some ideas about theta sounds, and developing an aspect of music theory with pc display models. Envision detailed but efficient sorting of sounds, colors, emotions, words, images that are optimally compatible or synergistic. Build this into a music writing/creating design and management program. Later if successful, could migrate to add video.
I've seen at least one interesting dissertation on music theory that analyzed some examples of classical music, displayed that analysis in live, graphed, dynamic colors (reproducible, not random) and identified elements that seemed to correspond to specific moods. But it's very complex in some ways and way too basic and cumbersome to be of much use yet. Intuition could develop such concepts into new composing/writing tools with break-thru potential, far beyond what Digi-design seems to have commercially available for general consumption todate.
I suppose I should explore this on a music-pc website/forum rather than here. However I came here for a different reason intially, and happened to see this thread.
