What if you had a device that could bring more variation to your rhythm tracks? That could inspire you to take your songs and arrangements in new directions? That would always be in time with your music, no matter how much you automated and modulated it?

Meet Euclid Rhythm Generator, the first Euclidean gate sequencer for Reason! It's based on an ancient mathematical algorithm, but you don't need a maths degree to use it — Just plug it into a gate input on your favourite sound source and start tweaking!

Product details

Euclid is rhythmical inspiration in a box, a constant source of surprises and happy accidents for your productions. It may seem simple on the surface, but once you get to know it you’ll find out how deep it really goes!

By automating and modulating its parameters you can create endless variations of your rhythm tracks. You can generate complex polymetric patterns by setting odd pattern lengths, or if you’re feeling extra-adventurous you can enable the new polyrhythmic resolution mode to create true polyrhythms like 1/5 over 1/3.

The clock input allows you to slave Euclid to almost anything, for example Reason’s built-in pattern devices. Or why not connect it to an LFO or another Euclid pattern? And the pitch output is really convenient when you want to trigger a specific key on a sampler, or play simple arpeggios.

Euclid comes with a big interactive display that visualizes your patterns in real time, including gate width, velocities, mutes, shuffle amount and current play position. You can draw mutes and velocities directly in the display, dragging across several steps at a time if you want. And the parameter values shown in the display are always up to date, even taking CV modulation into account!
