Sitka Instruments Gravity Eurorack Clock Module Now Open Source
Sitka Instruments let us know that they have open sourced Gravity, their 6-channel Arduino-based clock and trigger sequencer Eurorack module.
Combined with an optional MIDI Expander, Gravity is designed to provide a comprehensive clock solution.
“Gravity started 3 years ago as a hobby project. Back then I didn’t know much about electrical engineering and didn’t have a lot of experience in coding, and it was a huge help and inspiration for me to be able to see how more experienced people do stuff in open source projects. This helped me to learn a lot and get started pretty quickly,” explains developer Oleksiy Hrachov. “I decided that it’s time for me to give back to the community and make Gravity open source.”
The source is available now via Gitbhub.
By making Gravity open source, Hrachov is encouraging others to make DIY Gravity modules, to build and modify the code to meet their own needs and to use the code as a way of learning more about Arduino module development.
Features:
- 6 Multi-Mode Channels: Each channel can function as a steady clock, a randomly skipped clock, or a trigger sequencer.
- Clock Mode: Divide the master clock down to /128 or multiply it up to x24, perfect for driving sequencers or clocked modulations. Can be offset within a 24ppqn grid to add some movement to your sequences.
- Random Skip Mode: Adds rhythmic unpredictability to your patches.
- Trigger Sequencer Mode: Program percussive parts with a 16-step xox-style sequencer or live-record sequences by tapping the button. Store patterns in 2 banks with 8 memory slots each
- 2 CV Inputs: Freely assignable CV inputs (bipolar 5v) for modulating subdivisions, random skip chance, switching sequencer patterns, or even modulating master BPM.
- External Clock: Apart from internal clock, Gravity can be synced to other clock sources with 24ppqn or 1/16th note pulses, or MIDI clock (with MIDI expander).
- Expansion and Connectivity: Header pins on the back of the module for daisy-chaining and connecting a MIDI expander.
- MIDI Expander adds TRS MIDI clock input and output as well as extra x24 pulse output.
- Upgradeable Firmware

The Sitka Instruments Gravity Eurorack Clock Module is available for $199 USD, with the MIDI Expander.
