MIDI MACHINE

Features
Read 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 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."

Read full description

NoizyBeast is a kaiju. A feedback drone synth with no keyboard. A resonating string runs through filters, reverb and tape echo and feeds back into itself until it ignites. You don't play notes -- you provoke the beast and ride whatever comes back. Silence, breathing, drone, roar. Grow a noise that is yours alone. MAKE IT ROAR - FEEDBACK loops a tiny electrical signal and amplifies it into noise -- the same principle as microphone feedback. - FREQUENCY is the beast's voice. A free-sliding knob, not a keyboard, so you can glide between pitches. - BODY, in-loop filters, and a bit crusher you can place INSIDE the loop (the damage re-amplifies every pass). - Tempo-synced gate with tap tempo, metal resonance, and a gear-jamming Drag. Tap tempo drives the GATE for easy ducking-style movement. - Screaming wah, octave-up roar, vocal formants. - Six decay behaviours: string sustain, blooming-and-wilting drone, gate tails, plucked cycles, pitch dive-bombs, a swell cut dead. - A DJ-style filter at the output: season the sound with LPF and HPF. FREE VERSION Completely free as an instrument: all 34 knobs, every parameter (except Macro assignment), tap tempo, and the 18-preset Horror bank. NOIZYBEAST PRO (one-time purchase, no subscription) - Record, export and share your performances - All 108 presets - Save your own user presets - Assign your favourite parameters to the 3 macro knobs (move several parameters with one knob) There is no limit to the sounds you can make. Twist the knobs freely and grow a noise that is yours alone. For iPhone, iPad and Mac. One Pro purchase unlocks all three.
