WHAT IT IS Little Arp Monster is a MIDI arpeggiator that goes well beyond the usual. Build patterns from arpeggiated notes, full chords, rests, and even notes outside the chord, then let them evolve across a full arrangement. A finely tuned randomizer creates unique, musical patterns or alters your own, and a single Spice dial lets you decide whether you want classic, tasteful arps or wild ideas no traditional arp is able to generate. It's an arpeggiator for musicians who want to compose, not just repeat. WHAT IT DOES * Step grid: sequence scale degrees, full chords, and rests across 16 steps to build rhythmic patterns. Change the key and every note follows. * Scenes: each comes with its own settings and step grid. Use them for variations on one idea, or completely different motifs. * Arranger: set a progression that plays out over time - swap chord types, shift degrees, transpose the key, or switch scenes exactly when you choose. * Modulation lane: shape Velocity, Cutoff, Decay, or any CC. Locks to the same steps as your notes and follows when you switch scenes. * Randomize and Mutate: both always stay musical. Spice decides how adventurous it gets - from classic tasteful arps to patterns no arp could ever produce. * Built-in audition synth: hear your arp directly in the app without needing a connected instrument. REQUIREMENTS * iPad with iPadOS 15 or later, or iPhone with iOS 15 or later * An AUv3 host that supports MIDI processor plugins, e.g. AUM, Cubasis, or Drambo
