Tubbutec Brainstep

Step up the brains behind your system with the Brainstep Sequencer from Tubbutec, a 4-track sequencer, arpeggiator, and MIDI interface for Eurorack modular synths. In a mere 22 HP, Brainstep is well suited to wrangle multi-voice systems as a highly effective composition and performance tool.

Each track offers step sequencing with comprehensive options for accents, ties, probabilities, portamento, and more. Create sequences using the responsive panel interface, or record your patterns live using the built-in keyboard or a connected MIDI controller. The Brainstep also features a powerful arpeggiator with multiple modes, Euclidean triggering, and more—all of which can be used to record and overdub sequences on the fly.

Absent from Brainstep is the limitation of simple CV/gate pairs: each track features a pitch CV output alongside two assignable CV outputs, letting you sequence gates, ADSR envelopes, and free-running or syncable LFOs. Four assignable CV inputs allow you to use other signals to adjust parameters of each track, or even global swing amount. Happily fitting into any hybrid or fully-modular set up, Brainstep may be clocked or controlled internally, via MIDI, CV, or DIN Sync.

Even in smaller systems, the tracks of Brainstep will never be wasted, as each CV B output can also function as a LO-FI sample player for drums and percussion, with sample packs loaded via the SD card input. In addition to managing samples, this SD card is also used to save up to 24 patterns with up to 64 steps, allowing you to save entire loops, songs, and tuning setups for recall once you are ready to perform your next masterpiece.

Whether you are looking for a master sequencer that can help grow your loops into finished tracks, a flexible and comprehensive MIDI to CV solution, or an endlessly configurable performance controller, Brainstep from Tubbutec is an immensely powerful module worth keeping on your mind.
