Some kind of clip-based composition module
This would be a built-in module that folds out, ala the Regroove Mixer. I don't even know how this would look or work necessarily, but essentially it would be similar to Live's clip mode function. In that you could rearrange your composition on the fly, quickly finding new song ideas, as well as enhancing live-play. *I sometimes will randomly click my cursor to land at different points, while a track plays, & I will find cool ideas. By quickly skipping to 3-4 places in the track, weird accidental things can happen, & beautiful sounds/grooves/track ideas can be born. But taking that & turning it into a new track, or experimenting further is a bit laborious as of now.
A possible solution would be some kind of tool that folded out (like the Regroove module, but with a matrix layout), where we could trigger & add new clips (Blocks) & frankly manipulate endlessly. Being able to tweak the composition so dynamically would be a creative-joyride every time. Make a better mousetrap!
