Available as an assembled Module and as a DIY project.
This Module is currently available.
A basic, 8-channel clock source with adjustable tempo, phase shift, pulse width, and swing.
If you want to do virtually anything with rhythm in your modular rack, you will need a clock source to keep all your modules in sync. This module sends out triggers on each of its 8 channels that are all different subdivisions of the same tempo. Use them to trigger samples, ping envelopes, step sequencers, or whatever else you want to happen on beat.
All modules by FreeModular are open source. To make each DIY module more accesible for beginners, designer's website also includes a manual and assembly instructions, firmware source code, quick-order CSV files for components that can be uploaded to direct-order manufacturers, and faceplate/PCB files that can be uploaded to on-demand PCB manufacturers. Some modules are also available as kits or assembled modules through designer's Etsy.
