Np, by wavelengths do you mean like the view of the wave form being played like in your first post of this thread?? If thats what you mean then FL does do that. Theres a seperate section above the pattern section that you put automation and wave forms (you slice and stretch wave froms to your tempo, make loops and make cool stutter effects). I use it more than the patterns section, I only really use the patterns for drums. As for ableton, i only really used the manual thats in it, though i'm still in the process of learing it properly.
