Stellarizer is a creative performance-to-pattern MIDI sequencer designed to help musicians, producers, composers, and sound designers discover new ideas from the music they already play.

Instead of building every sequence step by step, Stellarizer starts with a MIDI performance. Play a phrase, capture it, and explore a collection of related patterns while retaining important elements of the original performance, including timing, contour, velocity, note length, and sustain.

The result is a more natural way to experiment with MIDI patterns and develop musical ideas inside your DAW.

Explore Patterns From Your Own Performance

Stellarizer provides several ways to transform and explore captured MIDI performances. The Pattern Playground lets you generate variations while the Near, Far, and Deep Space discovery ranges provide different levels of variation from your original idea.

You can shape important musical characteristics such as:

• Contour
• Rhythm
• Density
• Articulation
• Structure
• Timing
• Octave spread
• Note length
• Musical relationships

This makes it possible to move from subtle variations to more adventurous musical ideas without starting from an empty sequencer.

Keep Your Patterns In Key

With automatic Scale Lock, Stellarizer can keep generated patterns within your selected musical scale. You can also shift patterns across octaves to quickly explore different registers and find a better fit for your arrangement.

This makes Stellarizer particularly useful when experimenting with melodies, rhythmic phrases, bass patterns, arpeggiated ideas, and other MIDI-based musical material.

Capture, Save, and Organize Ideas

Stellarizer includes multiple performance capture modes, including Free, Synced, Fixed-Length, and Custom-Length recording.

Your captures and discoveries can be preserved in the Recordings Atlas, while presets provide a convenient way to save and organize your preferred settings.

The plugin also provides eight playable pattern slots, allowing you to keep multiple variations available and switch between them instantly, on the next beat, or on the next bar.

MIDI Designed for Your DAW

Stellarizer generates MIDI rather than audio, allowing it to work with the instruments already in your setup. Send its MIDI output to a software synthesizer, sampler, virtual instrument, or compatible external hardware.

When you discover a pattern you want to keep, you can export or drag the MIDI directly into your DAW for further editing and arrangement.
