ER-301 >> ER-301: Sound Computer for Eurorack Modular Synthesizers

The ER-301 is a voltage-controllable canvas for digital signal processing algorithms. One of the many characteristics that attracted me to modular synthesizers is that they enabled me to make the kind of music that I love away from the computer. However, not all digital audio tools can be elegantly and efficiently realized in a dedicated hardware form. So, I either had to deny myself those tools, or, go to the computer. The ER-301 is the culmination of 2 years of sweat and tears spent creating a third option. 3 panel flavors are available .







PLEASE TAKE NOTE! The ER-301 hardware is mature (revision 10) and robust, but there are a few things that you should note before purchasing: There is no manual (yet). Why? See next point. However there is a very active forum where you can get help and ask questions, as well as a wiki which is slowly growing with new content.

The software is still under heavy development which means frequent updates and bugs. The good news is that typically any bugs found are fixed within a few days. Specifications

Width: 30hp

Depth: 30mm from the back of the faceplate including the ribbon cable Power: refer to the wiki page on ER-301 Power. Latest Firmware Version: refer to the firmware page

** Some details might change without notice.

Official Manual COMING SOON: Software needs to stabilize some more before committing words to the page. In the meantime, there is a wiki that is growing and a forum dedicated to the ER-301 which I actively monitor.
