Notes

AI-powered MIDI pattern generator that runs directly inside your DAW. Pick a style, tweak the parameters, hit Gen — patterns flow straight into your MIDI track via processBlock.

Hybrid generation: music theory algorithms for the foundation, Claude AI for creative variations. Piano roll visualization, MIDI drag-to-DAW, and full DAW transport sync.

Inspired by the NEA (New Electronic Assistant) research paper on computational co-creativity for symbolic music generation.
