Selling my OXI One MK1 sequencer—without a doubt one of my favorite pieces of gear I've ever owned.
I've used it in almost every session whenever I needed to sketch rhythmic, melodic, or pattern-based ideas and turn them into a track as quickly as possible. It has become my go-to sequencer thanks to its speed and workflow, allowing me to stay focused on making music instead of programming.

Besides the classic sequencing modes (mono, poly, chord, etc.), it offers a wide range of generative sequencing tools. That has always been its biggest strength for me, often leading to unexpected and inspiring musical ideas.

The only reason I'm selling it is that the MK2 has been released. Otherwise, I'd happily keep it. The main advantage of the second generation—for my workflow—is the increase from four to eight sequencers. If you don't need to sequence a large number of instruments simultaneously, the MK1 is still more than capable and offers virtually the same creative workflow.

The sequencer is in excellent condition, almost like new. I purchased it directly from OXI Instruments in 2025.

The sale includes:

- OXI One MK1 sequencer
- Protective transport case
- USB-to-MIDI cable
- USB-to-TRS adapter
- OXI Split MIDI expander (purchased separately), which adds additional MIDI outputs, making it easy to connect and sequence more hardware without constantly swapping cables.

Feel free to get in touch if you have any questions.
