Introduction

Brainstep is a sequencer, arpeggiator, envelope and modulation generator, live performance tool, sample player, clock distributor, MIDI interface and more.
The brain of a eurorack system.

Feature List

• Four independent tracks, each with the following features:
• Step sequencer with multiple patterns, song mode and probability per step.
  Up to 44 patterns, 64 steps each.
  Notes have four per-step modifiers to trigger accents, portamento or tie.
  Each note can also be programmed to have one of 4 different gate lengths
  and two per-step amount levels.
  Gates and modifiers can have various probability levels.
  Seven directions including smart random modes allow even more sequence variation.
• Feature rich arpeggiator with multiple octaves and seven direction modes including 'order of key press'.
  Can inherit the 'chemistry' of existing sequences, for expressive, evolving arpeggios
  An Euclidian arpeggiator mode creates rhythmic arpeggios on the fly.
• Optimized for live performance: Quickly create or modify patterns, switch between arp and sequencer, record, change patterns, ...
  – all while playing.
• Live recording
  Record keyboard presses or arpeggiator output into patterns. The overdub mode makes this a perfect live composing tool.
• Envelope and modulation generator
  Each track can output up to 4 envelopes and 2 LFOs for a total of 16 envs and 8 LFOs:
  • ADSR envelopes with loop mode
  • Per step triggerable accent envelopes
  • Free running or syncable LFO with multiple waveforms including random S/H and a wide frequency range
• Drum sample output
  Each track can output drums samples:
  – Select between different sample packs or create your own
  – per step modifiers: Accent, double speed, half speed, reverse, gate length
• CV control: The four bipolar CV-inputs can be freely mapped to many parameters of envelopes, LFOs, sequencer, arpeggiator, probabilities and more
• Multiple clocking options: Internal clock generator, MIDI clock, analog clock / trigger
  Clock input and output: Can convert MIDI clock to analog clock, or be used as a central clock source. Clock divider per track.
  Swing generator for every clock.
• MIDI input and output: TRS-Midi and USB-C MIDI (Host or Device), Monophonic, Polyphonic and MPE support
• Microtonal support: Load scales / tunings from the SD card
• Save / Load complete sets via SD card
• Box contents: Comes with SD card containing samples and scales, Eurorack power cable and USB C to A adapter.
