MIDIbox SEQ v4+ // open source karma
Dreaming up one of the best MIDI step sequencers on planet earth
Originally developed by TK. and refined between 2016-2022 by antilog devices, this newest hardware revision of the MIDIbox sequencer V4 adds several advantages:
fully open source software - modify the sequencer to meet your requirements
designed for high-performance neutral-color dual OLED screens, instant update rates, no LCD ghosting
define the superflux LED color scheme of your dreams, i.e. cyan/red or red/green
high-quality, great-feeling multicolor LED backlit Matias switches: and high reliability and no more failing switches!
workflow bonus: an additional Matias switch "selection" row, allowing for direct track access using a single button
improved "selection mode wheel" allowing for one of multiple modes to use the new selection row
a compact form-factor case, specifically engineered by Hallik Engineering just for the v4+!
case integration with "all PCBs onboard", including 8 MIDI OUTs, 4 MIDI INs, and an integrated line driver (DB25) connector.
dual USB connectivity (also USB OTG), a quickly removable SD card, footswitch support
reliable power, utilizing a sturdy USB B socket (no more flimsy micro USB port)
is optionally 19" rack mount the unit or use in standard desktop mode
choose a left-hand or right-hand orientation
most important: optimized workflow, specifically designed by TK. :)
These features extend the already outstanding "basic" functionality of the V4:
The latest firmware and hardware configuration files can be downloaded from:
Available as essential kits now:
New: Your SEQ v4+ can now be easily expanded to drive a lot of eurorack gear with 8 CV/gate outputs, 8 trigger outputs and 8 clock outputs with the midiphy SEQ v4+ eurorack expansion modules.
