Specs
mono mode
Hold or draw one note and Rhythmizer 5 turns it into an endless stream of evolving melodies, chords and grooves. Every note comes from your settings - no A.I. involved.
POLY mode
Hold any chord and Rhythmizer becomes a randomising arpeggiator, with Chord Flux and Spread reshaping the voicing and the Fusion Fader blending from arpeggio to full chord.
scales and key freeze
Chose from one of 38 built-in scales, from standard Minor and Pentatonic all the way to Pelog or Hirajoshi - or build your own custom scales.
Groove generator
Inject chance-based grooves by subdivision, randomise velocity and gate length and humanise for subtle offset, with Density and Shuffle setting how busy and swung it plays.
step sequencer
Set your groove and play it straight, or introduce step probability and groove overrides while a Random Fill slider rewrites the whole pattern in one move.
cc mapping
Randomise your synths to your patterns - four map slots send Rhythmizer’s randomness to any parameter in your synth as MIDI CC
midi loop
Catch a phrase and loop it, from glitchy 32nds to multiple bars, perfect for grabbing the gold loops from an infinite stream, or for LFO-style repetition on the fly
drag-to-midi
There are plenty of ways to record Rhythmizer’s output - record to MIDI or audio in your DAW, or just drag whole performances out of Rhythmizer into a MIDI channel.
New - key freeze and chords
Lock Rhythmizer to the key of your track - you can’t hit a wrong note. Build chords by scale intervals, or randomise chord sequences to find new inspiration.
New - scale shapes
Unleash the new Branch, Cascade, Thumb and Pinky Shapes, all with direction modifiers and randomisation, to explore geometric possibilities with your melodies.
New - Groove presets
Browse from a library of groove starters, perfect for when you’ve got everything else just right but want to try a new rhythmic angle.
New - r-konnekt
A new plugin which loads both Rhythmizer 5 and your synth - one channel load, no MIDI routing needed. Zero added latency. Eight+ macros connect both devices. Real-time note visualiser.
