With XenCut fully-working, preliminary CrystalNet tests began tonight.  The testing was really just limited to observing how the XenCut engine operates under the parameters required to generate a structure.  The parameters differ greatly from those used to generate fractal melodies, since the concept of abstracting a structure to a fractal pattern is completely different than abstracting a melody to a fractal pattern.  In particular, the engine had to work with blocks of much smaller size (a single unit represented an entire movement of the composition) and deal with the fact that the starting material consisted of a few very large blocks placed at the root block.

Judging from a graphical display of the results of the cutting, CrystalNet (and XenCut) already seems to be doing a good job of handling the structure.  The results were similar to the diagrams I posted a while back that came with the original "random cutting structure module" idea.

My only concern is the depth of this abstraction.  Taking a composition, splitting it into pieces, then treating each instrument's instructions like physical block in space certainly doesn't seem as intuitive as treating the individual notes of a melody as blocks.  Though the output looks nice on screen, it may result in incoherence and seemingly-random part instructions.

I really won't know how well the method fractal/random cutting works for structures until CrystalNet is up and generating compositions.  If all goes well, that should only take another week or so.
