MIDI MACHINE

A fun, expressive MIDI controller with two modes: SPARK for endless inspiration, STRUCTURE for theory based chord sets. Explore, loop, and shape melodies with ease.

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."

Core Features

• 17 MIDI melody rows per set, automatically harmonized to your chosen key
• Each melody split into 10 playable tiles for real-time triggering of your favorite sounds
• SPARK mode for instant idea generation and exploration
• STRUCTURE mode for fixed chords mapped across key pairs, built in arpeggiator and chord group suggestions
• Keep randomizing to generate endless new melodic combinations while keeping your settings
• SAVE and recall full sets, including patterns, tempo, and performance modes

(SPARK)

• Note mode: trigger melodic sequences step-by-step
• Chord mode: play full harmonies instantly
• Loop ON / OFF: continuously cycle note sequences
• Hold OFF: slide across tiles for fluid, continuous runs
• Hold ON: trigger full sequences with a single tap
• Repeat ON / OFF: retrigger tiles rhythmically (1/4 to 1/64) for pattern creation
• Fixed velocity option for consistent dynamics
• Edit individual tile MIDI sequences
• Reverse entire rows
• Octave shift up or down
• Double or halve playback speed (Note mode)

(STRUCTURE)

• Group: Genre-based chord-progression suggestions. Highlights/labels tiles on the grid that form a real progression from the selected genre.
• Arp: Turns a held chord into a rolling sequence of individual notes.
  • Style – 16 note-order patterns (Up, Down, Converge, Pinky Up, Random, etc.). • Rate – Speed of each note: 1/4 to 1/64, relative to BPM. • Groove – Straight (default) or Swing 8/16/32 for a more human rhythmic feel.
• Hold OFF: slide across tiles for fluid, continuous runs
• Hold ON: trigger full sequences with a single tap
• Add automatic Bass Note to each chord
• Repeat ON / OFF: retrigger tiles rhythmically (1/4 to 1/64) for pattern creation
• Fixed velocity option for consistent dynamics

Performance Controls

• Global pitch shift in semitones for instant transposition of the entire set
• Adjustable BPM with tap tempo and fine control
• Flexible visible row count (5–17) for compact or expanded layouts
• Scrollable row view with FIRST ROW selection

MIDI MACHINE is built for musicians who want a different approach to creating ideas—fast, intuitive, and a little unpredictable. Whether you're sketching melodies or experimenting with generative patterns, it keeps everything playful, unique, and fun."
