Patterns for Jazz used for composition. Patterns X is the software equivalent to the much acclaimed book "Patterns For Jazz" by Jerry Coker et al. An infinite number of melodic shapes and patterns are created for use as practice materials or compositional needs. Categories include: Random Symmetric Patterns, PreSet Patterns, Random modal shapes, Random scaler shapes, Symmetric Modal/Scaler sequences, and Preset Modal/Scaler sequences. There are options for manipulation of the results by transposition, and inversion of interval direction and reversal of melodic direction, all of which yield some interesting a beautiful results.
