MIDI MACHINE
Read full descriptionHide full description
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 discoveryβrapidly 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 youβre in the studio or on the move with a minimal setup. You just start playing around and happy accidents happen."β¨β early user feedback 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.

TurboBeast is an engine you play: a drift synth with a gas pedal instead of a keyboard. Every rev is synthesized live from a combustion pulse train -- no samples, no loops. Pick a machine, start the engine, and drive the sound: squeeze the gas, stab the brake, bang through the gears, and slide the rear end until the tires sing. SIX MACHINES - 2ST RACER -- ringing two-stroke bike - SUPERSPORT -- screaming inline-four - CRUISER -- lazy V-twin thump - DRIFT SEDAN -- turbo four built to slide - ROTARY COUPE -- high-strung rotary - V8 MUSCLE -- heavy eight-cylinder rumble REAL DRIVING CONTROLS - ENGINE START, gas pedal with LATCH, brake and steering - Sequential or H-pattern shifting, gears 1-6 with real ratios - Gas + brake together breaks the rear loose: drift, tire squeal, backfire - Rev limiter stutter when you pin it SET THE SCENE - 6 tires x 5 road surfaces x 4 exhausts x 4 stages (highway overpass echo, local street, rural road, warehouse) - SUB layer for chest-deep low end, adjustable brake BITE and FADE PLAY IT LIKE AN INSTRUMENT - MIDI notes pitch the engine, so you can write riffs with it - 12 ready-made MIDI controller maps, pitch bend rides the gas - Works as an AUv3 plugin in GarageBand, Logic Pro, AUM, Cubasis and more - A guided first-launch tour points at the controls that matter FREE VERSION Free to drive: 2ST RACER and DRIFT SEDAN with every control, every tire, road, exhaust and stage.
