Reason Studios Arpeggio Lab Plug-in (Download)

Reason Studios Arpeggio Lab is a secret weapon against creative block, built not just to generate arpeggios, but to behave like a true musical partner. Instead of feeling mechanical or repetitive, it interacts with your ideas like an intuitive, imaginary bandmate. It’s highly playable, expressive, and designed to bring life and movement into your melodies.

Whenever you are stuck in a rut, out of ideas, or just need a fresh melodic layer, Arpeggio Lab is the tool to reach for. Whether you are looking for subtle inspiration or a complete shift in direction, Arpeggio Lab is there to help reignite your creative spark. It is included with Reason+ and is fully compatible with Reason 10.1 and later.

Designed to get you out of your head and into a flow-state of music production, Arpeggio Lab starts with a concept called the Anchor which is a steady rhythmic pattern that forms the backbone of your groove. Once your Anchor is set, you can build on it using Movement: a dynamic layer that introduces melodic variation, filling in gaps with arpeggio shapes that range from simple and sparse to dense and intricate. With just a few knob tweaks, your pattern can evolve dramatically, taking on entirely new shapes and feels.

The Hold function makes performance effortless by latching chords so you do not need to keep holding down keys. Choose from four smart Hold modes that adapt to different playstyles. The Humanise control brings a natural, expressive touch, mimicking the subtle timing and feel of a real musician's handstrokes.

Creative control goes even deeper with Modifiers, which let you mute individual steps, insert ratchets, or shift octaves for added complexity and interest. When you are in the mood to explore, you can dive into over 80 included patches, or simply use the Randomise function to discover new patterns instantly.

For modular users, Arpeggio Lab also supports CV/Gate, giving you the flexibility to split the arpeggio across different instruments and setups.

Whether you are layering textures, building a new track from scratch, or just jamming, Arpeggio Lab keeps you inspired and in motion.
