MIDI MACHINE vs Jamming Player

MIDI MACHINE is a fast, playful performance tool built for generating MIDI melodies on the fly. At the heart of MIDI MACHINE are two creative states: SPARK and STRUCTURE. SPARK mode is all about discovery—rapidly generating fresh melodic ideas and happy accidents. 17 randomized melodic rows drawn from an vast internal library, everything is locked to your chosen key. Each melody is sliced into 10 playable parts, letting you remix and reshape ideas in real time without ever hitting a creative wall. STRUCTURE mode lets you compose and perform with intention and move seamlessly between key pairs to trigger chords. Additionally, genre-based chord-progression suggestions form a real progression from a selected genre, so you can play a coherent sequence. This mode is designed to serve users with and without knowledge of music theory. "Super inspiring tool for sketching melodies quickly, whether you’re in the studio or on the move with a minimal setup. You just start playing around and happy accidents happen."
